My email account is blocked and I can't emails - help?

I have a large network of followers and recently sent an email to 102 of them. 

I got about 50 'failed permanently' responses and I've since learned that that the send limit is 50 which I wasn't aware of. Can you kindly unblock my email address so I can send emails again?
