Email Subscribers?

It might mean that on your website, someone signed up to be a receiver of your email newletters. You better write an article. Maybe you got your first customer for that. LOL! And please ignore this if I'm incorrect. I really haven't a clue.

Under your profile pic it says: join email list for when and if you send out an email campaign

Here is the link where they sign up on your profile

Never sent "newsletters". lol
Oh well, hope they won't be disappointed if they never hear from me.
