From Address & Sending Domain

The address your recipients see in the From line is built from two parts:

• Display name — set per campaign in the From Name field. Left blank, it is your organization's name.
• Email address — picked per broadcast in the From address field on the broadcast's Settings tab: one of your org's verified Sending Domains, or the shared CauseVox address newsletter@mg.causevox.com.

Three states you might see

• Verified domain — the From address picker lists each verified domain and the shared CauseVox address. A broadcast nobody has picked for sends from your most recently verified domain. Mail ships authenticated by DKIM with bounces routed back via your Return-Path.
• Pending verification — your org has added a domain but hasn't completed verification. Broadcasts send from the shared CauseVox address until DKIM and Return-Path both pass. Click Finish DNS setup to finish.
• No domain — broadcasts send from the shared CauseVox address. Click Send from your own domain to add one in Organization Settings.

The part before the @

When a broadcast sends from one of your own domains, you choose the part before the @ in the Part before the @ field — for example rob for rob@yourdomain.org. It defaults to newsletter. It can use letters, numbers, and . _ - +, with no dot at the start or end and no two dots in a row.

The shared CauseVox address is always newsletter@mg.causevox.com; the part before the @ can't be changed on it.

What happens if my domain regresses

Once a campaign is queued to send, the chosen domain is locked in. If verification regresses between compose and send (DNS records edited), the campaign fails with a clear error rather than silently falling back to the shared address — that way the deliberate choice you made isn't undone without warning.

If you delete a domain, broadcasts that haven't sent yet send from your next verified domain, or from the shared CauseVox address if there is none. Broadcasts that already went out keep showing the address they were sent from.
