Connect Claude & ChatGPT to Mailtrap

Ask your AI whether an email reached a customer, what your bounce rate was last week, or what the latest test email in a sandbox looks like. It reads Mailtrap email logs, sending stats, domains and suppressions, and manages contacts, lists, templates and campaigns. Delivery questions get answered without searching through logs by hand.

It gets sending stats for those dates: delivered, bounced, opened, clicked and spam.
“Show me the latest test email in our staging sandbox.”
It lists the messages caught in that sandbox and reads the newest one, including its HTML body.

Questions

What can the AI do in Mailtrap?

It can read accounts, sending domains, email logs, sending stats, suppressions, sandboxes and their test emails, contacts, contact lists, templates and campaigns with their stats. It can create and update contacts, lists and templates, update draft campaigns, schedule, send or cancel campaigns, and delete contacts.

Does the AI see my Mailtrap API token?

No. Your Mailtrap API token is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with logs and stats only. Sending or scheduling a campaign emails all its recipients, and cancelling a campaign or deleting a contact cannot be reversed, so those can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Mailtrap account.

Which permissions should my API token have?

Only the ones you need. You choose them when you click Add Token under Settings > API Tokens in Mailtrap, and you can combine that with the tools you switch on in HeyMyApps. Mailtrap shows the token only once, so paste it into HeyMyApps right after you create it.
