Email and SMS marketing connectors for Claude and ChatGPT.

Marketing connectors reach the list and the campaigns: who opened, which segment is biggest, what went out last month. Some can draft or schedule a campaign.

Sending to a list is hard to take back. Connectors that can send should leave the final send to you.
