Deliverability checklist

• Sending domain is verified in Resend. Unverified domains are far more likely to land in spam.
• Subject line looks clean. Add a subject line.
• Plain-text version included. Write a message body so a plain-text version can be generated.
• Message has real content. Very short or link-only emails are more likely to be flagged.

This is guidance, not a guarantee — final inbox placement also depends on your sending reputation and each recipient's filters.
