Email that lands

Transactional mail on our own deliverability layer.

Authenticated sending, automatic suppression handling, and inbound parsing — on infrastructure we run. DKIM, SPF, and DMARC are handled for you, and every send emits delivery events you can act on.

Transactional email

Preview

Fast, authenticated sending with a delivery event for every message.

A type-safe send API with idempotency keys means a retried request never double-sends, and every message emits delivered, opened, bounced, and complained events you can act on. Per-message and aggregate analytics come built in, so deliverability isn't a black box you only inspect after something goes wrong.

Templates

Coming soon

Versioned, type-safe templates with a live preview.

Templates are versioned with typed variables checked at build time, so a renamed field fails the build instead of shipping a broken email. A live preview renders against real sample data, so what you review is what the recipient receives.

Deliverability

Live

Automatic DKIM/SPF/DMARC and ongoing reputation monitoring.

Domain authentication is a single step, and DKIM, SPF, and DMARC are handled for you rather than hand-assembled in a DNS console. Warm-up and ongoing reputation monitoring keep sending healthy, with dedicated IPs available as volume grows.

Suppression & bounces

Live

Automatic bounce, complaint, and unsubscribe handling.

Hard bounces are suppressed automatically, and complaint and unsubscribe lists are maintained for you, so you stay compliant without writing the plumbing yourself. The result is a sender reputation that doesn't quietly erode from re-sending to addresses that already said no.

Inbound routing

Live

Parse inbound mail straight to a webhook or handler.

Inbound mail is parsed — headers, body, and attachments — and routed straight to your own webhook or handler, so receiving email is as programmable as sending it. It's what makes reply-to-app threads, ticketing, and email-driven workflows simple instead of a parsing project.

Mail — frequently asked questions

Do I have to configure DKIM, SPF, and DMARC myself?

No. Domain authentication is one step and we handle DKIM, SPF, and DMARC for you, plus warm-up and ongoing reputation monitoring.

What happens to bounces and complaints?

Hard bounces are suppressed automatically and complaint and unsubscribe lists are managed for you, so you stay compliant without writing the plumbing.

Can I receive email, not just send it?

Yes. Inbound routing parses incoming mail — headers, body, and attachments — straight to your own webhook or handler.

Do I get delivery events for each message?

Every send emits delivered, opened, bounced, and complained events, with per-message and aggregate analytics you can act on.

Are email templates type-safe?

Yes — templates are versioned with typed variables checked at build time, and you can preview them against real sample data.
