Do not keep sending from a temporary onboarding address if this is a production workflow.

from: 'noreply@yourdomain.com'
reply_to: 'you@yourdomain.com'

Update the email templates in Lovable

Make sure the app uses the verified sender address consistently and sends clean transactional content.

Copy this prompt

Resend emails are reaching inboxes as spam.
Please update the email sending code to use a verified domain sender address, simplify the template markup, and avoid spammy subject lines.

Prevent this next time
