You should not be spending days on email infrastructure.

One tool for transactional email. Another for newsletters. Another for inboxes. Then you still have to write templates, wire automations, handle bounces, manage unsubscribes, and localize everything yourself. It adds up fast.

MailKatana puts it all in one place.

Up and running in three steps

From zero to a full email system in under two minutes.

Step 3 - Ship

Turn on automations, send your first campaign, or plug the API into your app. One platform handles transactional, marketing, and inbound.

Everything you need to send, receive, and manage email

One platform, your entire email system.

Stop gluing together a sending API, a newsletter tool, a mailbox workaround, and a translation layer. Everything below lives in one dashboard, under one API key.

Pre-Wired Automations

Onboarding sequences, trial expiration nudges, abandoned cart flows, win-backs - generated the moment you sign up and ready to turn on.

Transactional Email

Welcome emails, password resets, receipts, OTPs. Send via REST, SDK, or SMTP. Resend-compatible API, so migration is fast.

Real Mailboxes

A real inbox, not a webhook parser. IMAP, webmail, aliases, forwarding, and filters - everything support@ and hello@ actually need. $5/month per mailbox.

MCP for AI Agents

Your agents can send email, read the inbox, reply, manage contacts, and trigger newsletters over MCP.

Developer and founder focused on shipping product

Built for devs and founders who want this done already

MailKatana is for SaaS teams that want email working fast and working properly.

You should be shipping product. Not rewriting password reset emails. Not wiring together a mailbox provider. Not trying to make four separate tools behave like one system.

You build the product. MailKatana handles the email.
