Hope you and your loved ones are safe and sound amidst this pandemic.
We are using below syntax in the SMTP Tab of the Delivery, but are still unable to see the list unsubscribe option in Gmail.
Solved! Go to Solution.
What content you are using the the HTML body?
Can you just write a dummy text and check it again on Yahoo/Outlook(Web)?
Somtimes it might not work because of poor IP reputation even if it is set up correctly.
As suggested, we did the test on the PROD and we are now able to see the Unsubscribe option appearing on the emails.
It appears to be reputation issue in the lower environments.
Thank you very much for your kind support.
Thanks & Regards
