Send from your domain
Verify with DNS; mail is DKIM-signed as you, not as us.
Email Early access
Verify your domain, then send transactional mail over a simple API or SMTP and route inbound replies straight to your webhook. Built on hardened SES; no reputation to rent.

How it works
Add a few DNS records to prove your domain, and send with an API call or standard SMTP. Inbound mail to your domain is parsed and POSTed to a webhook you control. DKIM, suppression, and delivery events are handled for you.
What you get
Verify with DNS; mail is DKIM-signed as you, not as us.
Inbound routes parse the message and POST it to your endpoint.
Deliveries, bounces and complaints arrive as events you can act on.
Bounces and complaints suppress automatically — your reputation, protected.
Pricing
Priced per message sent, with a monthly free floor — receiving is free. Free during early access.
Metered, and free while we open it up.
Rates land as Email graduates; early-access sending is free within limits.
