Omnisend MCP builds email and SMS automations inside ChatGPT
The author describes a single prompt that produced an editable email and SMS automation draft in an Omnisend account; the Omnisend MCP is listed in Claude and ChatGPT.
A few weeks ago, the AI plugged into my @omnisend account could already tell me where things were bleeding. Which segment had gone cold. Where CPA was quietly getting worse. It just couldn't do anything about any of it. That was already useful. Reports used to be the ceiling. Now it builds. I described one automation in a sentence. Trigger it off the BFCM early access signup form. One email, written as I'd actually send it, not like a template. It landed in the account as an editable draft, no build queue, no design ticket. Then I added a step. Two hours after the email, an SMS goes out to SMS-subscribed contacts only, reminding them that the code expires the moment the public sale opens. Changed the subject line and preheader by prompt too. Never opened the builder. Omnisend's MCP has been live in Anthropic's Claude Connector Directory since July 30, 2026. There's a ChatGPT listing too, if that's your stack. One thing worth saying plainly. It builds a draft, not a send. I read every word before anything goes out, and BFCM week is the worst week of the year to skip that step. If you're running Omnisend into BFCM, this is worth setting up before the week gets away from you.
