Improved
✅ What’s New
Previously, the Dedicated Header (From Name and From Email) was always used as the primary identity when sending emails through a dedicated domain.
With this update, we’ve changed how and when this header is applied:
🆕 Changes Introduced
1. Fallback Header Activation Only on DMARC Failure - The dedicated header will now only apply when DMARC alignment fails (based on SPF/DKIM logic).
2. Fallback Triggered When No Custom Header is Provided - If users do not specify a custom "From Name" or "From Email", and DMARC fails, the system will automatically apply the fallback header.
