Try asking

“How did yesterday's newsletter perform?”
The AI finds the message by send date and reads its delivery, open, click and sales statistics.
“Which emails has [email protected] received from us?”
It lists the messages sent to that subscriber, optionally for one publication.
“Subscribe [email protected] to the Daily Brief with the tag webinar.”
It finds the publication and creates the subscription with the tag.

What your AI can do

Messages and stats

List and read email and SMS messages, see delivery, open, click and sales stats, and create, schedule or cancel messages.

Subscribers and segments

Look up subscribers and their history, manage subscriptions and tags, and add or remove people from segments.

Publications, campaigns and billing

Read publications, campaigns, auto-responders and billing transactions, and send an auto-responder as a transactional email.

“How many subscribers are in the Lapsed buyers segment?”
It finds the segment and returns its subscriber counts.
“Move tomorrow's promo email to 9:00.”
It finds the message and sets the new send time. The message goes out to its recipients at that time.
“Show declined transactions from last week.”
It lists billing transactions in that date range that were declined, with customer email and publication.

Questions

What can the AI do in OptiPub?

The AI can read publications, messages and their stats, subscribers, subscriptions, segments, tags, campaigns, auto-responders and billing transactions. It can create subscriptions, update subscribers and subscriptions, add and remove segment members, create, schedule and cancel messages, and send transactional emails.

Does the AI see my OptiPub credentials?

No. Your OptiPub 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 or scheduling a message sends it to subscribers at the set time, a transactional email goes out at once, and cancelling a message or removing someone from a segment changes what people receive. These 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 PipMCP 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?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own OptiPub account.

What permissions does the OptiPub API key have?

An OptiPub API key has the permissions of the user who created it. Create it with a user whose access you are comfortable giving the AI, then switch on only the tools you want in PipMCP.
