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 the pricing overview.
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 summary for the exact terms.
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 summary.
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 in the credits overview. 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 billing terms and in the credits overview.
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 our privacy commitments and data processing terms.
Do you support customers outside the EU?
Yes, worldwide, with the exception of jurisdictions covered by applicable sanctions and export-control law. See our usage limits.
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 10.00, paid when you want them and never on a schedule.
