FIX PLAN · STEP 1 OF 1
Add a one-click unsubscribe header
Gmail and Yahoo require it for newsletters. Add these headers in your sending tool:
List-Unsubscribe: <https://yourdomain.com/unsub>
List-Unsubscribe-Post: List-Unsubscribe=One-Click
Copy
✓ Copied
Why: without it, bulk mail to Gmail and Yahoo is increasingly filtered or rejected.
Expected after the fix: 10 / 10 — then test again in one click.
