My account doesn't let me send any email, it says limit reached

i have not reached 100 subsmissions yet, why is it not letting me send emails. please help.

I think you are referring to sending the form through email in the publish wizard or forward/reply submission through the form submissions page. If yes, please note that we have a limit for this features. Free account is limited to only 20 outgoing emails per hour. You should resume the action on the next hour or share the form manually through your email account. 

If the above is not correct, please clarify so we can assist you further.
