MailCode Support

Help, bug reports, and feature requests

Every message is read by a human. Expect a reply within two business days.

The fastest way to report a bug is from inside the app: Help → Report a Problem. That attaches recent technical details automatically, which usually saves a round of questions.

When reporting a problem

Including these makes a fix far quicker:

Your macOS version and MailCode version (MailCode → About MailCode)
Account type — Exchange, Microsoft 365, or IMAP
What you did, what you expected, and what happened instead
Whether it happens every time or only sometimes

Please don't send passwords or full message contents. They are almost never needed, and never necessary to diagnose a problem.

Common questions

Which mail accounts does MailCode support?: Microsoft Exchange via EWS, Microsoft 365 with modern sign-in (OAuth), and any standard IMAP/SMTP provider — Gmail, iCloud, Fastmail, Yandex and others.
Where is my mail stored?: On your Mac, in a local archive that makes search and reading work offline. Nothing is stored on any server operated by the developer. See the Privacy Policy.
Does Send Later work when MailCode is closed?: In the Mac App Store version, scheduled messages are delivered while MailCode is running — including when it is hidden in the menu bar. If the app is fully quit at the scheduled time, the message goes out at the next launch. The direct-download version delivers via a background helper even when the app is closed.
Is the AI assistant required?: No. It is off until you turn it on, and it only ever sends text when you explicitly invoke an action. In the Mac App Store version it runs solely on a provider API key you supply. The direct-download version additionally offers MailCode AI credits, which relay requests through the developer's server — see the Privacy Policy for what that records.
Can I try it before connecting an account?: Yes. Launch MailCode without adding an account and it opens in Demo mode with a sample inbox and no network access.
How do I get my mail out?: Messages can be saved as standard .eml files, which any mail client can read. Your mail also remains on your own mail server throughout — MailCode never removes it unless you ask it to.

Feature requests

Send them to the address above. Requests that describe the problem you're trying to solve, rather than a specific solution, tend to produce better results.
