Your website keeps crashing when I am making a newsletter. A message will pop up every couple of minutes and say that something went wrong and asks me to refresh, leaving me with unsaved changes. Also when I transfer contacts from one list to another it doesn't actually move any except for maybe 100 out of 4000. You can reach me back at
Thank you for reaching out to the Community and bringing this to our attention. What browser are you working in? Are you having this same experience in a different browser or a private/incognito window? Testing your browser like this allows us to see if there are any add-ons that could effect how Constant Contact is working. Also, what is the name of the campaign you are working in? Is this template copied often? A template receiving this error message is an experience we are troubleshooting further. While we do not have a time estimate of when it will be resolved, recreating the email in a new campaign is a workaround we suggest in the meantime.
