Thank you for posting your question to the Community!
I'm sorry to hear that you are having issues with pasting text into that email. This issue could be the result of a couple things. First, when you create an email do you make a copy of a copy of a copy etc.? If so, there may be an issue with the template. Though copying your email a couple of times is not too big of a deal we have seen issues when the email is copied a number of times. To get around this we suggest creating a template that you never send. Simply leave the template as a draft and copy that draft when you need to send a new email.
Another thing that may be creating this issue is styles within the text that's being pasted. I highly suggest clearing the styles of that text before you paste it into Constant Contact. Click Here for more information on that process.
I hope that this helps but please let us know if you have additional questions or if this issue persists. Thank you for using Constant Contact, have a great day!
