Our email campaigns that come from me also show an email address that doesn't exist. It's similar to mine but has a slightly different first name and then also has this at the end of it: ccsend.com
I believe this is why some people don't receive our emails as this is an email address that isn't recognized and doesn't exist.
Any thoughts on why this happens?
