I received an email this morning from my Gmail account telling me to change my password because this person (reth1.p2-fw.constantcontact.com) tried to gain access to my account. Does this person work for constant contact?
Thanks for posting. It sounds like you may be using the Gmail tool for adding contacts to your account. Does this sound familiar? If so, this email could have sent because you will have to authorize the app to access your Constant Contact account.
