Thank you for reaching out to the Constant Contact Community. It's my pleasure to assist you today.
I'm so glad you reached out about this. The Constant Contact Branding does display on every email as long as you are in a trial account. However, should you convert to a paid account you can request that we remove that branding, in which case your footer would display the same except without the logo. Please feel free to reach out if you have further questions.
Thank you for choosing Constant Contact. Have a great weekend.
