Email verification service is a key component to any marketing or outreach program. It prevents undeliverable emails from lowering your sender reputation and depressing your deliverability metrics.

An email verification service  full of bad addresses is a waste of time, money and energy for your team. Not only does it hurt your performance metrics, but it also makes your email campaigns more likely to end up in the spam folder for many major ISPs. And worse yet, those useless addresses can also depress your sender reputation and cause your emails to stop getting delivered at all.
