Pombo review: Email platform for teams that build with AI, run by agents over MCP

What Pombo does

Pombo is an email platform that covers marketing campaigns, lifecycle sequences and transactional messages in one place, with a single contact list and one authenticated sending domain. It is built around AI agents: you connect an MCP client such as Claude, Claude Code, Cursor, ChatGPT or Codex, and the agent can set up sending, bring over a list, wire product events, draft sequences and fire test emails.

A brand page stores your voice, colours, buttons and font, and Pombo can read them from your website, so generated emails follow the same style. Everything the AI writes arrives as a draft, and the vendor states that every send waits for your approval.

Sequences can start from events posted to the API, and a dry run walks a sample contact through the steps before anything goes out. Transactional templates are sent by key from your backend. Pombo also offers a plain-English question box over your sending data, and a migration route for exports from other tools.

Our take

Pombo suits small product and engineering teams that already work with coding agents and want email handled through the same tools. The free plan is generous enough for evaluating the whole platform on a small list. Teams that want a long-established marketing suite with a published price ladder should check the vendor directly before committing.
