Recently, many email sign ups we’ve received, primarily through our google ads, have been suppressed and marked as “Email Bounced”. Even an email address from a friend of mine who is an email subscriber now is marked as “email bounced”. I understand that an email can bounced because it can be a fake or bad email address, but it’s a bit too big of a coincidence that many people signed up for our discount pop up form on our website (and came through a google ad) and were quickly marked as suppressed (email bounced reason) upon the first email sent to them, which is the discount code they signed up for.
Any thoughts or suggestions here on why this is happening?
