Emails going to spam
Verify your sending domain in Resend and ensure SPF/DKIM records are correctly set. Avoid using free email addresses (@gmail.com, @yahoo.com) as the from address.
API key invalid
Ensure you copied the full key (starts with re_). Keys are only shown once — if lost, generate a new one.
Domain verification stuck
DNS changes can take up to 48 hours. Use resend.com/domains to check record status. Try clicking Verify DNS Records again after waiting.
