The best conductor of customer conversations.
CopperMailer connects to your shared inbox, reads every incoming email, and drafts an accurate reply in your own voice, grounded in your help centre, your price list and your policies. You approve it, or let it send on its own. No message left to tarnish.
What you are actually buying
CopperMailer is cloud-hosted software sold as one-time purchases. You buy a licence once and keep it, and you buy credits (one credit, one reply) whenever you want more. There is no subscription, no renewal date and no physical product; nothing is shipped.
A connected inbox
You link a Gmail, Microsoft 365 or IMAP mailbox, or forward to a CopperMailer address. We read incoming mail so we can answer it.
An AI reply, drafted
Each message gets a proposed answer built from your own knowledge sources, with the sources cited so your team can check the wiring.
Send, or approve first
Auto-send on topics you trust, review queue for everything else. You choose per topic, and you can pull the plug at any moment.
Paid for in credits
One credit writes one reply, at 10 credits per dollar. Buy the size you want, once. Run out and it simply stops; nothing tops itself up.
How it works
Four steps, about twenty minutes, no engineer required.
-
Connect the wire
Authorise your mailbox over OAuth (Google Workspace, Microsoft 365) or add IMAP/SMTP credentials. We request the narrowest scopes that let us read and reply, and nothing more.
-
Feed the Patina Engine
Point us at your help centre URL, upload PDFs, or paste your macros. The model answers from these sources only, and picks up your tone the way copper picks up patina: gradually, from real contact.
-
Set the circuit
Decide which topics auto-send (order status, password resets, opening hours) and which always go to a human (refunds, complaints, anything legal). Add escalation rules and out-of-hours behaviour.
-
Watch the meter
The Ohm Meter dashboard shows resolution rate, first-response time, deflection and where your support flow still meets resistance. Export to CSV any time.
Features
Grounded replies, the review queue and routing come with every licence. The rest are one-time unlocks you buy only if you want them; see what they cost.
Grounded replies
Answers are generated strictly from the knowledge you supply, with citations. If the sources do not cover a question, CopperMailer says so and escalates instead of inventing an answer.
Patina Engine
Learns your house style from your last 90 days of sent mail: greeting, sign-off, formality, the lot. Nothing is used to train shared or third-party models.
Live Wire routing
Intent detection, language detection and sentiment on every inbound message, with rules to route, tag, snooze or escalate before a reply is ever drafted.
Human-in-the-loop
Review queue with one-click approve, edit or reject. Every edit teaches the model. Auto-send is off by default on every new topic.
Multilingual
Detects and replies in 31 languages, including Polish, German, French, Spanish and Portuguese, keeping your terminology consistent across all of them.
Circuit Builder
Visual rules: if intent is refund and order value is over a threshold, escalate to a named human. No code, no YAML, no surprises.
Ohm Meter analytics
Volume, deflection rate, median first response, approval rate, per-agent workload, and cost per resolved conversation. CSV export included.
Integrations
Gmail, Microsoft 365, IMAP/SMTP, Slack notifications, Zapier, HubSpot, Shopify order lookup, and a documented REST API with webhooks.
Copper-bottomed uptime
99.9% monthly uptime commitment, compensated in credits on the Alloy and Foundry licences. See the SLA for the exact terms.
Prices
Everything is a one-time payment in US dollars. A licence sets how many mailboxes you may connect and how many people may use the workspace; credits are bought separately and pay for the replies themselves. Nothing renews, nothing is shipped and no card is stored unless you ask us to save one.

Upgrading later costs the difference between the two licences; you are never asked to pay twice for what you already own. If we ever shut the Service down, clause 14.5 of the Terms gives you 90 days’ notice, a full refund of unused credits and a pro-rata refund of the licence over 36 months from purchase.
Credits: buy any amount you like
One credit drafts one reply. The base rate is 10 credits for USD 1.00. Type the number of credits, type a budget, or drag the slider: the price is worked out exactly, to the cent, with no fixed packages to squeeze into.
Credits are bought in whole units, so a typed budget is rounded to the nearest one. One-time payment: no subscription is created, and your card is not stored for future charges unless you ask us to save it.
| Credits | From $0.99 for 10 credits, at 10 credits per US dollar (every purchase is a flat 1¢ under the round number, so totals read $0.99, $9.99, $99.99…), in any whole quantity from 10 to 20,000 per purchase. One credit writes one reply. Credits do not expire while your account is open. |
|---|---|
| Free to start | 50 credits on approval of your account. No card is requested at any stage. |
| Currency and tax | All prices in USD. Any VAT, GST or sales tax we must collect is calculated and shown at checkout before you confirm, and itemised on your invoice. No handling or processing fees are ever added. |
| On your statement | Once per purchase, as JC Establishment – the legal name of the company trading as CopperMailer, so the entry is never a mystery. |
| Refunds | 14 days on anything unused, and unused paid credits within 24 months of purchase. Back to the original card via Stripe, no fee deducted. See the Refund Policy. |

Payment terms in plain language
Everything here is a one-time payment
We do not operate subscriptions. There is no billing cycle, no renewal date, no auto-charge and no card kept on file waiting to be used. Every purchase here is charged once, at the moment you confirm it, and that is the end of it. If you want more credits later, you come back and buy more, deliberately.
Currency and taxes
All prices are quoted and charged in US dollars (USD) and exclude VAT, GST and sales tax. Where we are required to collect tax (US sales tax in states where we have nexus, VAT or GST on consumer sales in countries that require it), it is calculated and shown at checkout before you pay and appears on your invoice. Where a destination country requires us to collect VAT or GST on sales to consumers, we register and account for it in that country and show it separately on your invoice.
What you get, and when
Licences, unlocks and credits are applied to your account immediately on successful payment, normally within seconds and always within one hour. Reply packs are available for download straight away. Services are delivered within the working days stated in the tables above, counted from the day we agree a start date with you. Nothing is physically shipped.
The 20,000-credit cap
Because a prepaid balance is your money until we have done the work, we cap it rather than encourage you to park cash with us: the most you can buy in one purchase is 20,000 credits ($1,999.99), and your unused paid balance is refundable to your card within 24 months of purchase, not just within 14 days. If you genuinely need a larger volume, write to sales@coppermailer.com and we will invoice it against an agreed usage schedule instead of taking a lump sum up front.
Refunds
14 days to change your mind on anything you have not used, plus statutory withdrawal rights for consumers in the EU and UK. Unused credits are refundable pro rata. The complete rules are in the Refund Policy.
Payment methods
Visa, Mastercard, American Express, Discover, Apple Pay and Google Pay. Payments are processed by Stripe, Inc.; card details are entered on Stripe-hosted fields and never reach CopperMailer servers. Your statement will show JC Establishment. That is the legal name of the company you are buying from; CopperMailer is its trading name, which is why the two do not read the same. We would rather tell you now than have you puzzle over a line on a statement in three weeks’ time.
We deliberately do not offer direct debit or any other mandate-based method. Those require you to authorise future pulls from your account, and since nothing here ever charges you twice, there is nothing for such a mandate to do.
At checkout you tick a box confirming you have read and accept the Terms of Service, the Privacy Policy and the Refund Policy. Because these are one-time purchases, there is no recurring-payment authorisation to give, and none is taken.
Pricing questions
Is anything at all recurring?
No. Not the licence, not the unlocks, not the credits, not the packs, not the services. Nothing on this site creates a subscription, and we do not store your card for later use unless you explicitly ask us to.
Do you offer discounts?
Registered non-profits and accredited educational institutions get 40% off any one-time purchase. Email sales@coppermailer.com with proof of status and we will send a discounted checkout link.
Where are my invoices?
Settings → Billing → Invoices holds every purchase as a PDF with full tax details, and each one is emailed to you at the time of purchase.
Credits
Credits are the fuel CopperMailer burns to write a reply. You buy exactly as many as you want, priced to the cent, and they sit in your balance until you use them. No meter runs in the background, nothing tops up on its own, and nothing expires.
10 credits for $1.00
That is the base rate, and one credit writes one reply. Buy any whole number from 10 to 20,000, priced to the exact cent, with bonus credits on larger quantities. Every purchase is a flat 1¢ under the round number, so the smallest purchase is $0.99, not $1.00.
They never expire
Expiring prepaid credits is a way of charging people for nothing. Yours stay in the balance for as long as your account is open.
No automatic top-up
When the balance reaches zero, reply generation pauses and we email you. We never charge a card to keep the lights on.
What each action costs
The full price list. Anything not on it is free.
| Action | Credits | Notes |
|---|---|---|
| Draft a reply into the review queue | 1 | The generation is the cost, so a draft you reject still counts. |
| Send a reply automatically | 1 | Same cost as a draft; auto-send is not charged extra. |
| Regenerate a draft you did not like | 1 | The first regeneration of any message is free. |
| Reply that reads an attachment (PDF, image, spreadsheet) | 2 | Up to 20 pages per message. |
| Reply longer than 1,500 words | 2 | Rare outside technical support. |
| Translate a reply into a second language | +1 | Only when you ask for a second version; replying in the sender’s own language is included in the 1. |
| Index or re-index knowledge sources | 5 per 100 pages | First index of up to 500 pages is free on every licence. |
| Classification, routing, tagging, sentiment | Free | Runs on every inbound message at no cost. |
| Sandbox and test replies | Free | Foundry sandbox workspaces never consume credits. |
| Failed generation (our error or a timeout) | Free | Automatically refunded to your balance within minutes. |
A rough guide. A small shop answering 20 emails a day uses about 600 credits a month, which costs $60.00. A two-person support team on 100 a day uses roughly 3,000, or $300.00. Your Ohm Meter dashboard shows the running average so you can see it rather than guess.
What it costs, and the bonus tiers
The price is linear: 10 credits per US dollar, which is 10 cents each, whatever quantity you buy, less a flat 1¢ off every purchase so the total always reads as an ordinary price rather than a round number: $0.99, $9.99, $99.99 and so on up to $1,999.99. Nothing is bundled into fixed packages, so the amount charged always lands on an exact cent.
On top of that, larger quantities earn free bonus credits. The tiers apply marginally, to each band separately, so there is never a point where buying one more credit would have cost you less overall.
| Credits in this band | Bonus on that band |
|---|---|
| The first 500 | None |
| 501 to 2,000 | 5% |
| 2,001 to 10,000 | 12% |
| Above 10,000 | 20% |
Worked through, that produces the following. Every figure below comes straight out of the calculator above.
| Credits bought | You pay | Bonus | Total credits | Effective rate |
|---|---|---|---|---|
| 10 (the minimum) | $0.99 | 0 | 10 | $0.0990 |
| 100 | $9.99 | 0 | 100 | $0.0999 |
| 250 | $24.99 | 0 | 250 | $0.1000 |
| 500 | $49.99 | 0 | 500 | $0.1000 |
| 1,000 | $99.99 | 25 | 1,025 | $0.0976 |
| 2,000 | $199.99 | 75 | 2,075 | $0.0964 |
| 5,000 | $499.99 | 435 | 5,435 | $0.0920 |
| 10,000 | $999.99 | 1,035 | 11,035 | $0.0906 |
| 20,000 (the maximum) | $1,999.99 | 3,035 | 23,035 | $0.0868 |
Bonus credits are rounded down to a whole credit. Because credits are whole units, a budget typed into the calculator is rounded to the nearest one: ask to spend $7.43 and you buy 74 credits for $7.39.
The rules, stated plainly
Credits are units of use, not money
A credit is a prepaid unit of access to the Service. It is not currency, not a stored-value or e-money instrument, not a gift card and not a security. Credits have no cash value, cannot be exchanged for money except as a refund under the Refund Policy, and cannot be sold, transferred or moved between accounts.
They never expire
Credits remain in your balance for as long as your account is open. If you close your account, you may request a refund of the unused balance first. Credits given free of charge (the 50 starter credits, promotional grants and goodwill top-ups) are not refundable, because you never paid for them.
Nothing renews and nothing tops up
There is no subscription and no automatic replenishment. At zero balance the Service stops drafting replies, sends you an email, and waits. Inbound mail keeps being received, classified and routed; you simply answer it yourself until you buy more. Optional low-balance email alerts can be set at any threshold you like in Settings → Credits.
Refunds
Unused paid credits are refundable pro rata for 24 months from the date of that purchase, at the effective rate you actually paid, for as long as your account is open. That is a rule, not a discretion we reserve. Beyond 24 months, the credits stay in your balance and never expire for use, but stop being eligible for a cash refund. Used credits are not refundable, because the work was done.
Your balance is always visible
Settings → Credits shows the current balance, every purchase with its invoice, and a line-by-line ledger of what consumed each credit and when. Export it to CSV whenever you like. We would rather you could check our arithmetic than take it on trust.
If we get it wrong
Credits deducted in error are returned as soon as we confirm it, and we do not make you argue the point. Write to billing@coppermailer.com with roughly when it happened; the ledger does the rest.
Credit questions
Do I need a licence to buy credits?
No. Credits work on the free account too; a licence raises how many mailboxes and seats you can use, not whether the engine runs.
Can I be charged more than the amount shown?
No. There is no overage, no usage bill and no card on file being charged in the background. The figure in the calculator is the entire charge, to the cent.
What happens to credits included with a licence?
Starter credits behave exactly like purchased ones and never expire. They are treated as part of the licence price for refund purposes.
Can several mailboxes share one balance?
Yes. One workspace, one balance, drawn on by every mailbox and every seat you have.
What if I need more than 20,000 credits?
Write to sales@coppermailer.com. We cap a single purchase at 20,000 credits on purpose: a prepaid balance is your money until we have done the work, and we would rather invoice larger volumes against an agreed schedule than hold a big lump sum of yours. Purchases do stack, so you can also simply buy again when you need to.
What if I close my account with credits left?
Ask before you close it and we refund the unused paid balance to your original payment method. See the Refund Policy.
What CopperMailer will not do
We are a reply tool, not a bulk sender. CopperMailer answers mail that people send to you. It does not send cold outreach, marketing blasts, unsolicited bulk email or scraped-list campaigns, and accounts used that way are terminated. See the Acceptable Use Policy.
We also make no promise about revenue, conversion or hiring outcomes. AI-generated text can be wrong; that is exactly why approval mode is the default and why you remain responsible for what leaves your mailbox.
Frequently asked questions
Can I try it for free?
Yes. Every new account gets 50 free credits and no card is requested. Most replies cost one credit, so that is roughly 40 to 50 real replies depending on how many carry attachments or run long; the exact cost of every action is above. When they run out nothing happens automatically; you decide whether to buy more.
How am I charged?
Once per purchase, in US dollars. A licence is a single payment, credits are a single payment, and nothing renews. Full detail is in the Terms of Service and above under Credits.
Is there anything to cancel?
No. There is no subscription, so there is nothing to cancel and nothing to forget about. If you stop buying credits, you stop paying us. Your account and licence stay put at no cost.
Who processes payments?
Stripe, Inc. and its affiliates. Card details are entered on Stripe-hosted pages and never reach CopperMailer servers. We store only the card brand, last four digits and expiry date returned to us by Stripe.
What happens to my email data?
It stays yours. We process it to run the service, never sell it, and never use your customers’ emails to train shared or third-party models. Details in the Privacy Policy and the Data Processing Addendum.
Do you support customers outside the EU?
Yes, worldwide, with the exception of jurisdictions covered by applicable sanctions and export-control law. See clause 16 of the Terms.
A small company that answers email for a living.
CopperMailer is made by JC Establishment LLC, a Wyoming company with no investors, no sales team and no growth targets to hit by Friday. We sell software once, we do not rent it to you monthly, and everything we will not do is written down as plainly as everything we will.
Who we are
JC Establishment LLC, organised under the laws of the State of Wyoming, United States, trading as CopperMailer. One entity, one bank account, one set of books. Nothing offshore, no holding structure, no other brands.
How we are funded
By customers. We have taken no venture capital and no outside investment, which is why the pricing is a one-time payment rather than a subscription designed to compound. If revenue stops, we stop; nobody is subsidising this.
How we work
Remotely, in a small team, in English and Polish. The Sheridan address is our registered office and handles post; it is not a staffed building, and we would rather say so than photograph someone else’s lobby.
Why this exists
Shared inboxes rot in a particular way. The first fifty messages a day are answerable from a help centre page that already exists; the last ten need judgement, patience and somebody who knows the account. Teams end up giving equal attention to both, then giving up, and the good questions get the same tired paragraph as the ones about opening hours.
CopperMailer takes the first fifty. It reads what arrives, finds the answer in sources you gave it, cites them, and puts a draft in front of a human until you trust it enough to stop looking. It is deliberately not a bulk sender, not a chatbot on your website, and not a system that decides anything about a customer. It replies to mail people chose to send you, which is a smaller idea than most AI products claim, and a lot more useful.
What we will not do
- Send cold outreach or bulk campaigns. Accounts that ask for it are declined; accounts that try it are closed. This is in the Acceptable Use Policy and it is not negotiable at any price.
- Train shared models on your customers’ email. Our model providers are contractually barred from training on data we submit, and we do not do it ourselves.
- Sell, rent or broker personal data. Not to advertisers, not to data brokers, not as “anonymised insights”.
- Invent social proof. There are no customer logos, testimonials or user counts anywhere on this site, because we are not going to make them up and we will not publish a customer’s name without a signed reason to.
- Claim certifications we do not hold. We have no SOC 2 report and no ISO 27001 certificate. See Security for what is actually in place, including the gaps.
How we got here
| 2025 | JC Establishment LLC registered in Wyoming. First working prototype answering our own support mail. |
|---|---|
| Early 2026 | Private testing with a handful of companies who put real inboxes through it and told us, at length, what was wrong. |
| March 2026 | v2.8: two-step verification, shorter sessions, complete data export. The unglamorous release that made it sellable. |
| April 2026 | v2.10: EU region in Frankfurt, optional PII redaction before inference. |
| July 2026 | v2.14: attachment-aware drafting, the most recent release. |
Accounts are still opened by hand, one at a time, after a short conversation. That will stop scaling at some point and we will deal with it then; for now it is the main reason our delivery reputation is intact.
Talk to us
Product and setup questions go to support@coppermailer.com, commercial ones to sales@coppermailer.com, and anything about this page to legal@coppermailer.com. Every address below reaches a person, Monday to Friday, 09:00 to 17:00 Mountain Time.
Copper doesn’t corrode. Neither should your trust.
You are handing us your inbox, the single most sensitive system in most companies. Here is exactly what we do to deserve that, described plainly enough that your security reviewer can check it.
Encryption
TLS 1.2+ for everything in transit, HSTS enforced. AES-256 at rest for databases, object storage and backups. Keys managed in our hosting provider’s KMS with automatic rotation, in the same region as the data they protect.
Least-privilege access
Mandatory MFA on every administrative account. Role-based permissions and immediate revocation when someone leaves. Support engineers reach production Customer Data only against a specific support request from you.
Tenant isolation
Every record carries a tenant identifier enforced at the data-access layer, with automated tests that fail the build if a query can cross tenants.
Narrow mailbox scopes
OAuth scopes are limited to reading and sending mail in the mailboxes you nominate. We never request access to Drive, calendars, contacts or admin directories. Revoke access from your provider at any time.
Testing
Automated dependency and secret scanning, static analysis in CI, and peer review on every change. We have not yet commissioned an external penetration test; when we do, the summary goes to any customer who asks.
Backups and recovery
Encrypted automated daily backups, retained 30 days, running across multiple availability zones at our hosting provider. Restores are tested before we rely on them, not on a published schedule we would rather not invent.
Audit logging
Logs of every administrative and data-access action, retained 12 months and exportable by your administrators on any licence.
AI-specific controls
Prompt-injection defences, output filtering and optional PII redaction before inference. Your customers’ email is never used to train shared or third-party models: we use commercial API terms that prohibit it, and retention at the model provider is governed by that provider’s published API policy, which we link from Annex B of the DPA rather than paraphrase.
Payment scope
Card data is captured in Stripe-hosted fields and never touches our servers. That keeps us in PCI DSS SAQ A scope, the narrowest there is. We store only a token and the last four digits.
Data residency
Our default hosting region is the United States. Customers who require their Customer Data to be stored at rest in the European Union can have their workspace provisioned in our EU region (Frankfurt, Germany) at no extra cost: ask before you connect a mailbox, because we cannot move a workspace between regions afterwards. The complete list of third parties, their locations and the transfer mechanisms is in Annex B of the DPA.
Compliance posture
This is the section where most vendors put badges. We would rather tell you exactly where we are, including the parts that are not finished:
| Item | Status |
|---|---|
| PCI DSS: SAQ A via Stripe-hosted payment fields | In place. Card data never reaches our servers. |
| GDPR: Article 28 DPA and Standard Contractual Clauses, offered to every customer | In place. See the DPA. |
| Data Protection Officer | Not appointed. We are not required to appoint one at our size and scope, so we have not pretended to. Privacy questions go to a named human at privacy@coppermailer.com. |
| External penetration test | Not yet commissioned. Planned once we are out of early access. We will publish the date here when it is booked, and not before. |
| ISO/IEC 27001 | Not certified and no audit currently scheduled. We follow the control families as a checklist, which is not the same thing and we will not imply that it is. |
| SOC 2 Type II | Not certified and no observation period under way. |
| HIPAA / PHI workloads | Not supported. Do not route protected health information through the Service. |
| PCI cardholder data in mailboxes | Not supported. Do not route full card numbers through the Service; the PII redaction unlock masks card-like numbers but is not a compliance control. |
Incident response
We run a documented incident-response plan with defined severities. If a personal data breach affects your data, we notify you without undue delay and in any event within 72 hours of becoming aware of it, with the facts we have and updates as the investigation continues, as committed in clause 7 of the DPA. We are a small team and do not staff a 24×7 rotation; incidents are worked as soon as they are detected and we will not claim a response time we cannot hold. For major incidents we publish a written post-incident review to affected customers within ten business days.
Responsible disclosure
If you have found a vulnerability, we want to hear from you and we will not send lawyers after you for telling us.
- Report to security@coppermailer.com. Our contact details and disclosure policy are published at
coppermailer.com/.well-known/security.txt. If you need to send something encrypted, ask us and we will agree a channel with you. - We acknowledge within 2 business days and give an initial assessment within 10.
- Please test only against your own account, do not access, modify or exfiltrate other customers’ data, do not run denial-of-service or spam tests, and give us reasonable time to fix an issue before disclosing it publicly.
- Researchers who follow this process act with our authorisation and we will not pursue legal action. We credit reporters who want credit, and pay discretionary bounties for high-impact findings.
- Out of scope: findings that require a compromised device, social engineering of our staff, missing best-practice headers with no demonstrable impact, and automated scanner output without a proof of concept.
Your side of the wire
Security is shared. Enable MFA on your workspace, review who has admin rights, keep auto-send restricted to topics that genuinely do not need judgement, and rotate API keys when someone leaves. We provide the controls; the configuration is yours.
Security questionnaires and a signed DPA are available to every customer, including free accounts, and we do not gate either behind an enterprise contract. Write to sales@coppermailer.com. If your procurement process requires a SOC 2 report or an external penetration test summary, we do not have one yet and would rather tell you now than at the end of your review.
Drop us a line. A real one.
Every address below reaches a person, not a queue that swallows things. We answer support mail ourselves, using CopperMailer, naturally, with a human reading every reply before it goes out.

United States
A limited liability company organised under the laws of the State of Wyoming, United States.
CopperMailer is a trading name of JC Establishment LLC, which is the seller, the invoicing entity and the merchant of record for every purchase.
This is our registered address and where legal notices should be sent. We work remotely and this is a mail-handling address, not a staffed office, so please write rather than visit: email reaches us far faster than post.

We are a small team and we do not run a night shift, so we are not going to sell you one. Outages are alerted to us automatically and worked as soon as someone is awake to work them; everything else is picked up the next working morning. If round-the-clock cover is a hard requirement for you, tell us before you buy rather than after.
Languages
We answer in English and Polish. The Service itself replies to your customers in 31 languages.
Before you write about billing
Most billing questions are answered instantly in Settings → Billing: invoices as PDF, your credit ledger line by line, licence upgrades and removal of any saved payment method. There is no subscription to cancel, so there is nothing to chase us about. If the answer is not there, write to us and we will sort it.
How to buy
Every purchase is a single payment: a licence, a feature unlock, credits, a reply pack or a setup service. There is no subscription to sign up for and nothing renews, so buying is deliberately unremarkable:
-
Ask for an account
Accounts are opened by hand rather than by self-service: send the account request form and we answer within one business day. No card is requested, and approval brings 50 free credits to test the quality on your own mail before you spend anything.
-
Pick what you need
Choose a licence, and set the number of credits you want in the calculator above. If you are not sure how many you will use, start small: purchases stack, and credits never expire.
-
Pay once, through Stripe
Card details are entered on Stripe’s own payment page. You confirm acceptance of the Terms, Privacy Policy and Refund Policy with a checkbox, and the charge is taken once. Your statement shows
JC Establishment, the legal name of the company behind CopperMailer. -
It is applied immediately
Licences, unlocks and credits appear on the account within seconds, and an invoice reaches your inbox at the same time.
Prefer to be invoiced, need a purchase order, or want a volume above 20,000 credits? Write to sales@coppermailer.com and a person will answer within one business day.
Complaints
If something has gone wrong, write to legal@coppermailer.com with “Complaint” in the subject. We acknowledge within 2 business days and give a substantive answer within 14 days.
Data protection complaints can be sent to privacy@coppermailer.com. If you are in the EEA or the UK, you may also lodge a complaint with your national supervisory authority.
Getting an account
There is no instant sign-up button here, and that is on purpose. CopperMailer reads and answers real customer mail, so every workspace is opened by a person after a short check. It takes us a few minutes and it is the reason our delivery reputation is intact.
-
Send the request
Six fields on the account request form: who you are, which mailbox you want answered and roughly how much of it there is.
-
We check it, by hand
We confirm the domain is yours, that you want inbound replies rather than outbound campaigns, and run a standard sanctions and watchlist screen on the applicant. Answered within one business day, normally the same morning.
-
Your workspace opens
A sign-in link, an owner account, 50 free credits, and a 20-minute setup call if you want one. US region by default, EU region on request.
Ready to close the circuit?
Start with 50 free credits and no card. The Wire licence is USD 39.99 once, and credits start at USD 0.99, paid when you want them and never on a schedule.
