I apologize for any confusion there may with these charges on your account! Have you recently upgraded to our Email Plus or uploaded a large list of contacts? Taking either of these actions are reasons why your monthly bill would increase. With that said, the good news is we have billing support available who can help look into this charge further for you. Due to account security we are unable to share your billing details or authorize any billing changes here in the Community. Our Billing Support can however be reached by phone at these hours and numbers.
