ZeroBounce's free tier renews: 100 checks a month, read on zerobounce.net/pricing on 24 September 2026. That makes it one of only three vendors, out of 16 read that day, whose free credits refill monthly. The other two were emailverify.io and Hunter. ZeroBounce also runs a free single-address checker on its site.
Paid use starts with a minimum. ZeroBounce's pay-as-you-go entry was $39 for 2,000 credits on 24 September 2026, and its 10,000 and 100,000 volumes were sold on subscription. The ZeroBounce pricing breakdown lists each tier and what rolls over while a plan is active.
Billing rules decide what the free checks buy. ZeroBounce doesn't bill unknown results, and it bills catch-all addresses, which it scores separately (zerobounce.net, read 24 September 2026). That's the common market rule, and ZapBounce uses it too: valid, invalid and catch_all use a credit, while unknown and duplicates never do.
ZapBounce gives every account 100 free checks a month with no card, on any email address you sign up with. Paid checks start at $5 for 1,000 with no minimum order, $25 buys 10,000 on pay-as-you-go, and credits never expire. The ZapBounce vs ZeroBounce page sets the two price lists side by side.
The names sound alike, but the companies are separate. ZapBounce runs its own SMTP check on port 25 and isn't a reseller or a version of ZeroBounce. The answer on whether ZapBounce is the same as ZeroBounce covers the difference.
