Email verification is different than email cleaning, although both are a part of email hygiene. 

Email verification refers to the process of verifying the validity of the email addresses in your list. It helps ensure the addresses are correct, and you can get rid of invalid or wrong emails. 

Email cleaning, on the other hand, is keeping your email list updated. It involves regularly removing invalid, inactive, and outdated email addresses from your email list that no longer provide value to your marketing campaigns. It’s done either manually or using email cleaner apps.
