Bring your AI.
Sendly speaks Model Context Protocol — the open standard for AI tool use. Connect Claude, Cursor or any MCP-aware agent, over OAuth or with a secret key. You choose what it may do, one permission at a time: the ones that cannot be undone — sending mail, revoking API keys — arrive unchecked, behind a warning.

One dashboard, everything you need.
Most email tools weren't built for agents.
Everything you need. Nothing you don't.
Visual workflows that branch on opens, clicks, and custom events. Drag, drop, ship.
Filter your audience on any property. Segments update in real time as contacts change.
Schedule, A/B test, and track marketing broadcasts alongside transactional sends.
Delivery, opens, clicks, bounces. Per domain, per tag, per template — drilled all the way down.
Receive at a verified address, route to a webhook, and treat replies like any other event.
Separate identities for transactional and marketing mail, suggested when you add a domain. Each gets its own DKIM, SPF and DMARC — so a campaign's complaints never reach the reputation your password resets go out on.
Replace your email stack.

Questions, answered.
- What is Sendly?
- Sendly is an email platform for developers: one REST API for transactional email, marketing campaigns and visual automation workflows, built on AWS SES, with contacts, segments, templates, webhooks and an event stream in the same account.
- Can I move from Resend, SendGrid, Postmark or Mailgun without rewriting my code?
- For transactional sends, yes. Sendly's API also accepts the send requests of Resend, SendGrid, Postmark, Mailgun and Plunk, so an existing SDK keeps working once you change its base URL and API key. Each migration guide names the one setting to change.
- Is there a free tier?
- Yes: 5,000 emails per calendar month, with no card required and the full API, SDKs and webhooks included. Email sent on the free tier carries a small "Sent with Sendly" footer. Above that you pay per email sent, with no monthly fee.
- Can AI agents use Sendly?
- Yes. Sendly runs an MCP server at https://app.sendly.now/api/mcp. An MCP client such as Claude or ChatGPT connects over OAuth, and you choose the permissions it gets when you approve it.
- Where are the docs and the API reference?
- On docs.sendly.now, which also publishes llms.txt and llms-full.txt for AI tools and the OpenAPI document the official TypeScript and Python SDKs are generated from.
