Connect Claude & ChatGPT to SMTP.com

“How did our email do yesterday?”
The AI gets sending statistics for the last day: delivered, failed, opened, clicked and more.
“Which messages on the transactional channel failed since this morning?”
It lists messages on that channel from the start time you give, filtered to failed events.
“Which recipient ISPs had the most failures yesterday?”
It gets the stats for the last day grouped by recipient ISP.

What your AI can do

Send email

Send an email through one of your channels with from address, to, cc and bcc, subject and text or HTML parts.

Stats and messages

Read delivered, failed, opened and clicked counts by channel, domain, recipient domain or ISP, and list sent messages with their events.

Reports, channels and domains

Request and read CSV event reports, and look up channels with their quota and the sending domains on your account.

“Send a test email from our main channel to me.”
It sends an email with a subject and a text or HTML body through the channel. The email goes out right away.
“Make a CSV report of all events on the newsletter channel for March.”
It requests a report for that period. When it is ready, the AI can fetch the download link.
“Which sending domains do we have, and are they enabled?”
It lists the domains registered on your account and whether each one is enabled.

Questions

What can the AI do in SMTP.com?

The AI can read your account details, channels, sending domains, sending statistics, sent messages with their delivery events and reports. It can send an email through a channel and request a one-off CSV report of email events.

Does the AI see my SMTP.com credentials?

No. Your SMTP.com 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 read-only. Sending an email reaches a real recipient right away, so send_email can require your approval before it runs. 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 SMTP.com account.

Which SMTP.com plan do I need?

Your SMTP.com plan must include the Email API, because that is what HeyMyApps connects to. You also need an API key from the API keys section of the SMTP.com dashboard.
