I am preparing an email campaign via "Send via email."After moving
forward with "Prepare" and "Confirm,"I noticed that there is a gap
between registered addresses=subscribers (under “Services” on “Profiles
and Audiences") and the final delivery target number. This is the first
email and these addresses (subscribers) were registered beforehand so
they had no way to unsubscribe, and the domains are not blacklisted.Any
ideas why?Thank you.
