Pombo

Email platforms assume a person sits in the dashboard and writes each campaign. Teams that build with agents want the opposite: a tool an assistant can operate, with a human approving what goes out.

Pombo works that way. Connect an MCP client and it sets up sending, moves your list over with unsubscribes intact and drafts campaigns and sequences from a single sentence. It reads your voice from your website, so the result sounds like you rather than a template. Nothing is sent until you approve it, and you can ask about your own data in plain English and get a ready sequence back.
