A representative scenario showing how a sales team verified prospect lists before outreach to protect their domain and lift reply rates.

The challenge
Sourced and aged prospect lists carried 20 to 40% invalid addresses. Sending cold outreach to them caused hard bounces, triggered spam filters, and threatened to get the team's sending domain blacklisted, hurting deliverability for everyone.
The solution
The team verified every prospect list before the first send, removing invalid, catch-all and disposable addresses, and used the confidence score to prioritize the most reachable contacts.
Frequently asked questions
Does verification contact prospects?
No. It confirms a mailbox exists using DNS and SMTP without delivering any message, so prospects are never emailed during the check.
