Connect Claude & ChatGPT to Anypost

Ask your AI whether an email was delivered, why an address gets no mail, or to send a message through Anypost. It can read email events, templates and sending domains, publish template drafts, re-check a domain's DNS records and manage the suppression list.

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

Try asking

“Was the password reset email to [email protected] delivered?”
The AI lists recent email events and shows whether the message to that recipient was delivered, opened or bounced.
“Why is [email protected] not getting our emails?”
It checks whether the address is suppressed and why: a bounce, a complaint or an unsubscribe.
“Send a short test email from [email protected] to me.”
It sends the email right away from your verified domain. A sent email cannot be recalled.

What your AI can do

Sending and events

Send a single email with HTML or text, cc, bcc and reply-to, and read events such as delivered, opened, bounced and complained.

Templates

List and read templates, read a template's unpublished draft, publish it, or make a copy.

Domains and suppressions

Check sending domains and their DNS records, re-run verification, and look up or remove suppressed addresses.

“Is our new sending domain verified yet?”
It re-checks the domain's DNS records, updates the verification status and shows the domain with its DNS records.
“Publish the draft of our welcome template.”
It reads the template draft and publishes it, so new emails sent with that template use the new version.
“List every address on the suppression list.”
It lists the suppressed addresses that Anypost will not send to.

Questions

What can the AI do in Anypost?

The AI can read your account identity, email events, templates, template drafts, sending domains and the suppression list. It can send an email, publish or duplicate a template, re-check a domain's verification and remove an address from the suppression list.

Does the AI see my Anypost API key?

No. Your Anypost API key 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 lookups only. Sending an email reaches a real inbox and cannot be recalled, and removing a suppression lets mail go to that address again, so both 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 Anypost account.

Which API key permission should I use?

Create a key with the full permission if you want the AI to read events, templates, domains and suppressions. A send_only key can only send mail. The secret starts with ap_ and Anypost shows it only once, so paste it into HeyMyApps right after you create it.
