subscribers. This is a process wherein each person who signs up for your
list is sent an email after subscribing with a tagged link in it that

associated with that confirmation.
Where we may go to independently review your opt-in confirmation
Also, we would like to know where we may sign up for your mailing list
in order to test out its opt-in confirmation functionality.
If your bulk email usage is not in compliance with these policies, we
must ask that you cease any bulk email activity immediately until you
have become compliant. The easiest way to do that is to use our
Announcement list feature, which you can access here:

logging aspects of the policy for you, so that you don't have to.
