Email-channel infrastructure — sending domains, verified senders, suppression, inbound receiving, and threads.
The email resource covers the infrastructure behind email sending and receiving:
the domains you send from, the senders you send as, suppression, inbound routing,
and conversation threads. The actual send call lives on
Messages; this resource is the setup and inbound
surface around it.
What you can do
- Domains — add a sending domain, verify its DNS, check status, and enable receiving for inbound.
- Senders — register and verify the From addresses you send as.
- Suppression (blocks) — manage the suppression list and inspect why an address was blocked.
- Inbound — configure catch-all and forwarding rules for received mail.
- Threads — read inbound conversation threads and their messages.
- Stats — pull aggregate email statistics.
Before you can send from your domain
Brand-new accounts can send immediately on a shared domain. To send from your own domain, add and verify it first — see Verify your domain for the DNS walkthrough.
Shared conventions (auth, status codes, errors, pagination) are in the REST API reference. Per-operation request and response detail is in the sidebar.
