Connect Claude & ChatGPT to Mailgun

Ask your AI why a customer never got an email, how last week's sending went, or to add someone to a mailing list. It reads events, sending stats, domains, templates, mailing lists and the bounce, complaint and unsubscribe lists, and can send and resend email through your Mailgun domains. You trace delivery problems without digging through logs.

Connect Mailgun free

Free plan, no credit card. Takes about a minute.

Try asking

“Did the order confirmation to [email protected] get delivered?”
The AI lists the events for that recipient on your domain and shows whether the email was accepted, delivered, failed or opened.
“How did our email perform last week?”
It reads the sending stats for the week by day, with delivered, opened, clicked, bounced and complained counts and rates.
“Is [email protected] on our bounce list? If so, remove him.”
It checks the domain's bounce list and removes the address, so Mailgun sends to it again.

What your AI can do

Sending and events

Send email with text, HTML or a stored template, resend stored messages, and trace each email through its events.

Domains, stats and templates

Check domain state and required DNS records, read sending stats by day, domain or tag, and read templates.

Lists and suppressions

Create mailing lists and add, update or remove members. Check and clear bounces, complaints and unsubscribes.

“Add [email protected] to [email protected].”
It adds her as a member of that mailing list, or updates her if she is already on it.
“Resend yesterday's invoice email to the customer's new address.”
It finds the email in the events, fetches the stored message and resends it to the new address.
“Which DNS records does mg.example.com still need?”
It reads the domain with its state and the DNS records needed for sending and receiving.

Questions

What can the AI do in Mailgun?

The AI can read domains, events, stored messages, sending stats, templates, mailing lists and members, and the bounce, complaint and unsubscribe lists. It can send and resend email, create mailing lists, add, update and remove members, and remove addresses from the suppression lists.

Why is the username api?

Mailgun uses basic authentication with the fixed username api and your private API key as the password. HeyMyApps sends both with each call, so you only enter them once.

Does the AI see my Mailgun API key?

No. Your Mailgun private API key is encrypted at rest and never shown to the AI. Once saved, it is not shown again, not even to you. The AI only works through the tools you switch on.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. A sent email cannot be recalled, and removing an address from a bounce, complaint or unsubscribe list makes Mailgun send to it again. These actions 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, turn on Developer mode and add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link works in Claude under Settings › Connectors › Add custom connector, and in Cursor.

What does it cost?

HeyMyApps has a free plan, and you do not need a credit card to start. Paid plans bill per completed task, so you pay for work the AI actually finishes. You also need your own Mailgun account.
