Thank you for reaching out to the Community! I apologize that our website is moving slow on your computer. We would love to help troubleshoot this! Can you please try accessing Constant Contact on a different browser and a different computer to see if either of those two options make a difference? You can also actively see how our website is doing by going to our status page. Thanks!
I apologize you too are having this experience with our site. I can understand how important it is to easily work in your account. You mentioned seeing this slowness when creating your email. Are you copying a previous email or creating a brand new one? I have taken a peek at your account and can see you are still working in our previous Legacy Editor campaigns. Copying and reusing a template in this editor too often or too much can cause formatting issues. With that said, what browser are you working in? Are you seeing this happen with your campaign in any other browser or even a private/incognito window? Testing your browser like is a great step to take and helps determine if there are any 3rd party add-ons that could affect how Constant Contact works.
