Set up Resend
Verify your domain (Resend recommends a subdomain, such as news.example.com), then create an API key with Sending access, limited to that domain if you like.
Set the outgoing mail
On Settings › Outgoing mail, set up an SMTP server: the Server is smtp.resend.com, the Port 587, the Username resend and the Password the API key. Port 587 uses STARTTLS; port 465 is TLS from the first byte. Every setting is in the mail guide.
# Or from the CLI
mailpiece settings sending smtp update --address smtp.resend.com --port 587 \
--username resend --password API_KEY
# The app's sign-in mail, optional

Set a from address on your verified domain in Settings › Sending and send a test issue from any post. If it does not arrive, look in Resend's email log.
