Hello everyone. I am trying to add the Unsubscribe button to my header while sending with my Amazon SES account, but it doesn't appear on Yahoo emails. Can please someone help me?
List-Unsubscribe: <https://nutrition.co/?address=x&topic=x>, <mailto:unsubscribe@ nutrition.co?subject=TopicUnsubscribe>
List-Unsubscribe-Post: List-Unsubscribe=One-Click
I tried to add this to parameters on my header, but the Unsubscribe button didn't appear.
