Sending domains

Sending domains are not a Settings section yet. The spam check already looks at SPF, DMARC and MX.

ReferenceChecked 2026-10-10

What works today

  • The email spam check looks at your sending domain's SPF, DMARC and MX records. A campaign shows "Sending domain set up" with the result ("SPF, DMARC and MX found", or "Something is missing: see below").
  • The mailboxes table shows each mailbox's sending domain.

What does not work

  • Adding a sending domain and getting the DNS records to copy.
  • A custom tracking domain.

To set up DNS records for your sending domain, do it with your domain provider and then run the spam check. See Set up: connect a mailbox.
