As the title says.
Gmail does not accept any mails from our woocommerce shop since we installed the FPD Plugin and marks them as spam.

We tried to get rid of the product thumbnail in the mails but that seems to be not the problem... The Mails still get marked as spam.
What can we do now?
Please open a support ticket so we can have a closer look at your issue.
