Activate Email Sending

Registers the domain with Resend and turns on open/click tracking through trackingSubdomain, defaulting to links. Does not start verification — call Verify Email DNS after the records exist. Sets sending status to PENDING.

Disable Email Sending

Turns sending off and clears tracking state. If inbound still uses the same Resend registration, that registration is kept and only sending is disabled. Otherwise the domain is removed from Resend. Re-activating issues a new record set rather than reusing a stale one.
