There is no List-Unsubscribe record in the header

[2k20films]

Hi, I don't have a List-Unsubscribe record in my header. Apparently it not inserted by Milwizz automatically as stated. I've set "List-unsubscribe header email" at /backend/index.php/settings/customers/campaigns. I've specified REPLY-TO address, but still, there is no sign of List Unsubscribe in the header. Could you please let me know, how to fix it.

What type of delivery server are you using? because that header might get removed by a 3rd-party delivery server...

Hi, thank you for your reply. I use DigitalOcean VPN and MailWizz build-in SwiftMailer

Then the header is there for sure, let's check it
Please add test-tthskkq3s@srv1.mail-tester.com to your email list and send a campaign to your list, then let me know.

Hi thank you for your reply, I eventually realized that was a problem. I sent out test emails, so it was not an actual campaign, what is why List-Unsubscribe tag is not showing up, but then I sent a real campaign and added a test email to the mailing list, and then I checked the List-Unsubscribe tag was there.
