Email verification is the validation and authentication process where emails sent to customers are tested to know how genuine they are and if they are received by real people, not robots.

Every three months, it’s a good idea to double-check your email list. You may check each email as it arrives before (or as soon as) it enters your CRM. However, if you already have an email list that you haven’t checked, it’s a good idea to go ahead and do so.
