We've used the most recent list of addresses we had to send an email to the whole class, but we know some emails must no longer be active since some are 10 years old (we missed a reunion during the pandemic, unfortunately). Is there a way to find out which emails have not gone through?

Because the bounceback system does not seem to be properly functioning, there is not a way via Class Creator to reliably know which emails have not gone through.

Some administrators send emails to all classmates via the administrator's private email as a check to see which ones go through.

Thank you. I may just have to do that.
