FAQ
Why should I verify my email list?
Sending to invalid or risky addresses causes hard bounces, which hurt your sender reputation and can land future emails in spam. Verification removes bad addresses before you send, protecting deliverability and improving the accuracy of your open and click metrics. It's especially important for older lists or purchased data.
What is the best free email verification tool?
Several services offer free credits to start: ZeroBounce, Truelist, and Hunter all provide free verifications so you can test accuracy before paying. Free tiers are usually enough to clean a small list or trial a tool. For larger lists, most providers use affordable pay-as-you-go or subscription pricing.
