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 write one piece of software and license it; we sell it once rather than rent it to you monthly, and everything we will not do is written down as plainly as everything we will. The company details are on this page, not buried.
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. Sheridan is our registered office and the address on every invoice, contract and legal notice; the work itself is done from wherever each of us is that week, which is why we ask you to write rather than turn up.
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.
Release history
Current version 2.14. Releases go out when something is finished rather than on a calendar, and the list below is the whole history, not a selection of the flattering parts.
| Version | Date | What changed |
|---|---|---|
| 2.14 | July 2026 | Attachment-aware drafting: PDFs, images and spreadsheets are read before the reply is written, up to 20 pages per message. Current release. |
| 2.10 | April 2026 | EU region in Frankfurt, chosen at workspace creation. Optional PII redaction before inference. |
| 2.8 | March 2026 | Two-step verification, shorter sessions, complete data export. The unglamorous release that made it sellable. |
| 2.0 | Early 2026 | Private testing with a handful of companies who put real inboxes through it and told us, at length, what was wrong. |
| 1.0 | 2025 | JC Establishment LLC registered in Wyoming. First working prototype, answering our own support mail. |
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.

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 the company’s registered address, the address printed on every invoice, and where legal notices and service of process should be sent. We are a small remote team, so please write or call rather than visit: post is answered, but email and the telephone reach us in hours rather than days.
Support hours
| Monday to Friday | 09:00 to 17:00 Mountain Time (17:00 to 01:00 CET) |
|---|---|
| Saturday to Sunday | Closed |
| US federal holidays | Closed |
| If you are in Europe | Our working day starts at 17:00 CET, so a message you send during the Polish or German working day is read the same day and normally answered the same evening. In practice an email sent before lunch gets its answer before you finish for the day. |
Klienci z Polski: wszystkie informacje przed zakupem – sprzedawca, dostawa, ceny, prawo odstąpienia od umowy w 14 dni z wzorem oświadczenia, reklamacje i bezpłatna pomoc konsumencka – są zebrane po polsku na stronie Informacje dla klientów z Polski.
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.
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.
