Connect Claude & ChatGPT to Sender

Ask your AI how your last newsletter did, who clicked, or to add a new signup to the right group in Sender. It can list and add subscribers, manage groups, read segments, create draft campaigns and send or schedule them, and send a single transactional email. Email marketing questions get answered without opening reports one by one.

Try asking

“How did last week's newsletter do?”
The AI finds the sent campaign and reads its stats, then lists who opened it, which links were clicked and who unsubscribed.
“Add [email protected] to the Customers group without starting any automations.”
It finds the group and adds the subscriber with trigger_automation set to false.
“Create a group called Workshop 2026 and add everyone from the Waitlist group to it.”
It creates the group, lists the subscribers in Waitlist and adds their email addresses to the new group.

Questions

What can the AI do in Sender?

The AI can read subscribers, groups, segments, custom fields, campaigns with their stats, opens, clicks and unsubscribes, and automation workflows. It can add subscribers, create groups, add or remove subscribers from groups, create draft campaigns, send or schedule campaigns and send a single transactional email.

Does the AI see my Sender API token?

No. Your Sender 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 reports and lookups only. Sending or scheduling a campaign emails every recipient and cannot be undone, and 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 Sender account.

Will adding subscribers start my automations?

It can. In Sender, joining a group can trigger automations. The AI can set trigger_automation to false when it adds a subscriber or adds people to a group, so ask for that when you do not want automations to start.
