I have a Zoho mail free account with a limitation to send 1000 mails per user. My Qs is do i get to send more mails if I sign up for a paid account? As this limitation is leading to my account getting blocked!

I get a mail saying that the account is bloacked because the number of emails sent were higher ( probably then the limit) After clicking on unblock link it starts working again.

I would like this blocking to be automatically removed in my account the next day.

Pls provide more info on the same, and the way out.

Best Regards, Vikas
