Pombo

What Pombo is

Pombo is an email platform for marketing, lifecycle, and transactional email, with tools that let teams work alongside AI agents. From a brief, AI can prepare an audience, email, and campaign, but the result stays in draft form until someone reviews and sends it. Multi-step sequences can begin when someone signs up, an event occurs, or a chosen date arrives. Pombo can also derive a brand voice and style from a website and use them in emails, templates, and campaigns.

Users can ask plain-English questions about sending data and get suggested campaigns, sequences, or list-cleanup actions. For agent access, Pombo provides an MCP server with OAuth for Claude, Cursor, ChatGPT, Codex, and other MCP clients. Agent actions are logged, and sending requires approval. Its REST API supports contacts, events, and transactional email; listed integrations and services can send events through a webhook or API. Pombo says it can help move contacts, templates, and sequences from services such as Mailchimp and Klaviyo, while carrying unsubscribes over. The free plan allows up to 1,000 contacts and 1,000 sends each week, with a Pombo-branded footer. Paid plans start at $29/mo, bill monthly, and include unlimited sending and seats.

Who it suits

Pombo suits teams handling marketing, lifecycle, or transactional email that want to use AI agents while retaining approval over sending. It may also fit teams connecting email activity to services such as Stripe, Segment, Clerk, Supabase, Zapier, or Make through webhooks or the API.

Limits

The free plan is limited to 1,000 contacts and 1,000 email sends per week, and includes a Pombo-branded footer. Paid plans start at $29/mo and include unlimited sending and seats.
