Marketing → Settings has four fields.
- From Email: the sender on every campaign email. While it is empty or an example address (example.com, .org or .net) the page warns "Campaigns will not send" and every send or schedule is refused.
- From Name: shown as Name <address>.
- Track email opens and Track link clicks: read when a campaign is sent. Changing them does not affect mail already queued.
The unsubscribe link is always added to every campaign email and cannot be turned off. A daily-send limit exists in the data but has no screen and is not used.
