Hello @teresat942 ,
Are you needing to have a Constant Contact online marketing account to perform your class functions? As in, do you need to be able to build and send emails, make ads, make social media posts and track engagement, build a website, etc.?
If you're needing to sign up with a specific school or class's system, I'd suggest reaching out to them by replying to one of their emails, or by reaching out whomever your educator or college's dean is. Once you've confirmed all that with them, you can just let your current trial account with us expire on its own.
