Why you should validate your lists

User stack icon

Contact lists go bad

23% of lists go stale every year, which means you’re wasting time and money sending to bad addresses that affect your deliverability. It is industry best practice to verify lists every 90 days.

Warning sign icon

Bad contacts alert spam filters

25% of emails go to the spam folder. Sending to invalid email address increases that percentage and means that emails that you worked hard to create are never read.

Sending reputation matters

A good sending reputation is tied to lower bounce rates. Having a good sender reputation leads to an increase in open rates, which in turn, leads to an increase in revenue.
