Symfony/amazon-mailer DNC rate

Does anyone have an issue with high unsubscribe rate while using:
symfony/amazon-mailer dependency?
When I tested it, the one click unsubscribe header disappeared…

Now I switched back to etailor’s Amazon SES plugin. I hope DNC rate will go down.

Interesting, not sure why would that be, perhaps looking into code would provide more insight. I might take a look, thanks for letting us now.
