Connect Claude & ChatGPT to SendX

Ask your AI how a campaign did, which list a contact is on, or to tag everyone who signed up at an event in SendX. It can search, create and update contacts, manage lists, tags and email templates, create campaigns and read their reports. Tools that send email are separate, so you decide whether they are on.

Try asking

  • “How did the April product update campaign do?”

    The AI finds the campaign and reads its delivery, open, click and unsubscribe numbers.

  • “Add [email protected] to the Webinar list with the tag trial.”

    It creates the contact with the list and tag, or updates the contact if it already exists.

  • “Tag these five contacts as vip and remove the tag lead.”

    It adds and removes the tags on each contact by email.

What your AI can do

Contacts, lists and tags

Search, create and update contacts, add and remove tags, create and rename lists, and unsubscribe or delete contacts.

Campaigns and reports

List and read campaigns, create new ones for lists or tags, and read delivery, open and click statistics.

Templates and sending

Read and create email templates, and send one-off or template emails when you switch those tools on.

  • “Create a list called Beta testers.”

    It creates the new contact list and returns its ID.

  • “Which email templates do we have for onboarding?”

    It searches your saved templates and can open one to show its subject and HTML.

  • “Unsubscribe [email protected].”

    It unsubscribes the contact so they stop receiving campaigns.

Questions

What can the AI do in SendX?

It can search and read contacts, lists, tags, campaigns, campaign reports, senders, email templates, custom fields and team members. It can create and update contacts, add and remove tags, create and rename lists, create tags, templates and campaigns, unsubscribe or delete contacts, and send transactional or template emails.

Does the AI see my SendX credentials?

No. Your SendX credentials are encrypted at rest and never shown to the AI. After you save them, they are 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. Creating a campaign set to send immediately, sending an email and deleting a contact cannot be undone, so those tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open 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 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 SendX account.

Can the AI send a campaign by itself?

Only if you let it. A campaign is created with a schedule setting that either sends it right away or schedules it, and sent emails cannot be recalled. You can keep create_campaign, send_email and send_template_email switched off, or require your approval so you see each one before it runs.
