I work in a company. We have multiple customers signed up on our websites. Currently, we do not perform email verification of customer Sign-ups. I wanted to check whether this will be a GDPR concern. Does GDPR mandate us to do email verification during sign ups?
I came across one issue where a user could use the email id of any other random person. Our marketing team may reach out to the email with marketing emails. This can be an concern wherein the actual email id user raises an issue that he/she has not signed on our website
