Transactional email

Send transactional email — welcome messages, receipts, password resets — from your own verified domain. Orizon gives you a clean REST API, automatic DKIM signing, suppression handling, and delivery tracking.

How it works

Verify a domain. Add a sending domain and publish the DKIM, SPF, MX and DMARC records Orizon generates. See Domains & DKIM/SPF.
Create an email API key.Generate a send key in the dashboard's email section.
Send. POST to /v1/emails with a from on your verified domain, recipients, a subject, and HTML or text.
Track. Every send is logged with a status timeline — sent, delivered, bounced, complained.

Suppression & compliance

Hard bounces and spam complaints automatically add the recipient to a suppression list, and suppressed addresses are silently dropped from future sends. You can also add or remove suppressions manually. This keeps your sender reputation healthy.
