Deliverability standards have tightened dramatically entering 2027. With Google Workspace, Microsoft 365, and cold outreach sequencers like Instantly and Smartlead enforcing strict 2% bounce ceilings, choosing the right email verification platform determines whether your campaigns land in the Primary Inbox—and whether you pay $59 or $649 per 100,000 leads.

Head-to-Head Breakdown of Top Providers
- 1. MailVeri (Best Overall Value & Developer Stack): Delivers 99%+ verification precision starting at $0.0002/check ($59 for 100K, $299 for 1M). Includes Universal Credits that never expire, 100% automatic refunds on
UNKNOWNresults, native Clay HTTP API support, and an official MCP server for AI agents. - 2. ZeroBounce: Offers data append and scoring add-ons, but increased Pay-As-You-Go prices to $129 for 10K and $649 for 100K (more than 10x MailVeri's rate). Read our MailVeri vs ZeroBounce comparison.
- 3. NeverBounce: Enterprise batch cleaner owned by ZoomInfo, but charges $400 per 100K, expires unused credits after 12 months, and bills credits on inconclusive
UNKNOWNchecks. See MailVeri vs NeverBounce. - 4. BounceBan & Scrubby.io: Marketed to cold emailers for catch-all verification, but BounceBan charges $350 per 100K (6x more than MailVeri) and Scrubby.io charges ~$3,000 per 100K while waiting 48–72 hours to send live burner emails into prospect inboxes.
- 5. Hunter.io & Snov.io: Built primarily for email finding; bundling verification into recurring monthly subscriptions ($299/mo on Hunter or $738/mo on Snov.io for 100K) quickly burns lead-finding quotas.
