Client Group - Error in the settings of the Sending tab


New Member

I'm setting up a Customer Group and when I go to the Sending tab and I put the values:

Sending quota: Any value
Time value: 1
Time unit: Monthly

MAILWIZZ stops sending any email from this group and returns me the error message.

Changing the values of Time value or Time unit to any other value the sending of emails returns to work.

How do I solve this problem?
