What is Mailly?

Mailly is a complete email platform built for AI agents: sending, receiving and marketing in one place, with every step visible in your workspace.

Agents connect through

  • MCP
  • CLI
  • HTTP API
  • SMTP
  • Webhooks

Free to start. No card needed.

  • Send

    Send notifications and transactional email over the API or SMTP, with versioned templates, your own domain and a delivery record for every message.

  • Receive

    Every agent gets its own address. Each back-and-forth stays in one thread, so your agent can follow the conversation and draft a reply.

  • Campaigns & automation

    Manage contacts and audiences, run campaigns, and chain triggers, sends and waits into workflows, with results for every recipient.

  • You stay in control

    Give agents only the permissions they need. Hosted agents draft, and nothing goes out until you approve it.
