Thank you for contacting the Constant Contact Community. It's my pleasure to assist you today.
I'm sorry you are seeing a difference in your account billing. Due to account security, we can't discuss billing via the Community. However, you can reach out to our Billing Department directly and they will be able to tell you why your billing increased and why sales tax is now being added. In the meantime, if you have further questions you can always feel free to reach out to us here.
Thank you for choosing Constant Contact. Have a great day!
