DeBounce strengths

DeBounce starts from $0.00045 a check, on tiers from 5,000 to 5,000,000 credits, read in September 2026. Credits never expire, and 100 free credits get you going. It lists native apps for HubSpot, Mailchimp, Klaviyo, Mailjet, SparkPost, Google Sheets, WordPress and WooCommerce, plus Zapier. Its 97.5% deliverability guarantee pays back in credits when a list falls short, under its stated conditions.

ZeroBounce strengths

ZeroBounce lets you start small and keep testing free. $39 buys a 2,000-credit minimum, and a business domain gets 100 free checks every month. Unknowns aren't charged, per its facts page, and each catch-all address gets a score from 1 to 10. Blacklist monitoring, inbox placement tests and DMARC tools share the same account.

What separates DeBounce from ZeroBounce

Catch-all rows set the real bill on a B2B file. DeBounce charges its base rate for the standard check, then 10 credits an address for catch-all validation, read on 24 September 2026. ZeroBounce scores every catch-all address from 1 to 10 as part of the result. Count the accept-all share of your list first, then price both, and read our catch-all glossary entry for why those rows are hard.

Speed differs by a clear margin at 100,000 addresses. ZeroBounce states 45 to 60 minutes, and DeBounce states under 2 hours, both read on 24 September 2026. For a nightly job the gap rarely matters. For a list you need back before a launch this afternoon, it might.

The rest of the choice is what sits around the verdict. DeBounce plugs into the email platform where your list already lives. ZeroBounce adds tools that watch your sending reputation after the clean. The ZeroBounce pricing breakdown and the DeBounce pricing breakdown set out each ladder.

What DeBounce and ZeroBounce both run into

Vendor accuracy percentages in this category count how often a returned verdict was right. They are calculated after the catch-alls and the servers that refuse to answer have left the denominator. Hunter tested 15 verifiers on 3,000 real business addresses (3 November 2025) and measured 31.2% to 70.0% overall. Both kinds of figure are real and they are not measuring the same thing.
