Bouncer earns 4.8/5 on G2 and 4.9/5 on Capterra — among the highest-rated email verification tools on the market — for one reason: accuracy. Here is the honest scorecard.
What real users say: Reviewers on G2 and Capterra consistently highlight accuracy, the never-expiring credits and the no-charge-for-duplicates policy, while flagging the higher per-credit pricing at low volumes as the trade-off you accept for this much accuracy.
Run Bouncer on every client list before campaigns and the accuracy is genuinely best-in-class. Hard bounce rate dropped from 6% to under 0.5% across 12 cold-email accounts. Credits never expiring is a huge deal — we stockpile during sales and use them across all clients.

Tested Bouncer head-to-head against ZeroBounce and NeverBounce on a 50k list. Bouncer caught 8% more risky emails and saved us a sender-reputation hit. Pricing is slightly higher per credit at small volumes but fair at our scale (250k+/month).

Wired up Bouncer’s real-time API on our SaaS signup form and bot signups dropped 95% overnight. The 100 free credits got us through testing. Honest gripe: per-credit pricing is steeper than EmailListVerify at low volume, but the accuracy gap justified it for us.
