Hey there @JerryS542 !
To protect your account's security, I cannot discuss billing information on the community page. However, I can definitely understand how it can be confusing to see a charge that you might have not expected. Looks like you are on one of our email plans, here's a great article explaining How and When You're Charged for Constant Contact.
If this still doesn't quite answer your question, I advise calling into our billing team. We would be more than happy to discuss this charge with you! You can reach our billing support team here.
