MailPoet Team: Can you please elaborate on what this means? I run a huge site that's a magazine from 1945, and most authors are now dead with "ghost" WP users that don't correspond to a valid email address. They're eating into my 50K limit. Would I be able to disable the "WordPress users" list so only active subscribers count?

Kejda Gjermani: Hi, please get in touch with me at kim [at] mailpoet dot com. I'll assist you better for your situation.
