No matter where you get your data from (ZoomInfo, Apollo, or one of the other many database providers) email verification is an important step in cold outreach. It ensures that the emails you are sending are actually reaching the intended recipient, not bouncing and not being sent to the spam folder.
An email verification service goes deeper than many email validation tools that are embedded in your email marketing software. Those tools often check simply to see if an email address exists. But today, that’s not enough information to determine if you should be sending emails to an address. Email verification tools give you an understanding of the quality of your email data and protect your sender's reputation, limiting your emails that end up in spam.
