I am using Zoho mail for a non-profit group, a 4-H organization, in which often I have to send out information to members in a group email.  Last night I received an error message when trying to send out a message.  The error message reads " Unable to send message;Reason:550 5.4.6 Mail rate exceeded limit".  Is there a way to get this limit removed?  I really have like zoho mail, but if I am unable to send the group emails, I will have to switch providers.

Thank you,

Kelly Allgeier
