ZeroBounce alternative: comparison

ZeroBounce is one of the best-known email verification services. If you are looking at alternatives, this comparison puts PricklyMails and ZeroBounce side by side, strictly on points you can check for yourself: pricing, free tier, credit expiry, uncertain results, catch-all domains, your data, the API, and the MCP server.

The comparison at a glance

Pricing

ZeroBounce bills one credit per address validated, at a price per credit that falls with the volume you buy. PricklyMails bills each check in tokens: address format 1, domain 2, mailbox 4, disposable address 1, generic address 1, free mailbox 1, catch-all 4. The tables count PricklyMails with two setups:

• Essential, 8 tokens: address format, domain, mailbox, and disposable address, on every plan.
• Full, 14 tokens: every check, catch-all included, on the Pro plan and above.

Each price stays in its vendor's currency, euros for PricklyMails and US dollars for ZeroBounce: we do not convert, since the exchange rate moves. PricklyMails charges no VAT (VAT exemption for small businesses, article 293 B of the French General Tax Code); ZeroBounce says it also accepts payment in euros.

Pay as you go

Without a subscription, ZeroBounce sells credit packs whose price per credit falls with volume, and PricklyMails sells tokens at a single rate, €1 per 1,000 tokens.

Subscriptions

ZeroBounce has one subscription, ZeroBounce ONE, from 10,000 credits a month. PricklyMails has four paid plans, each granting tokens every month.

Credit expiry

PricklyMails tokens never expire, whether they come from a plan, a top-up, or your signup, and they stay on your balance after you cancel. At ZeroBounce, credits on accounts created on or before June 1, 2026 never expire. On accounts created after that date, purchased credits expire two years after the most recent purchase; they do not expire while a ZeroBounce ONE subscription is active, and once it ends, they stay valid for two years from its last day.

What is not billed

In both cases, the real cost lands a little below these figures. At ZeroBounce, unknown results and duplicates are not charged. At PricklyMails, duplicates within one request are not charged, an address verified recently is served again for free, and tests that got no answer are refunded.

Uncertain results

Unknown results

ZeroBounce does not charge for an "unknown" result. PricklyMails refunds the tests that got no answer (the mailbox test and, when you ran it, the catch-all test) and bills the checks that completed, such as the address format and the domain. On an unknown result, ZeroBounce costs you nothing; PricklyMails costs you the checks that did answer.

Gmail, Outlook, and Yahoo

Gmail, Outlook, and Yahoo never confirm that a mailbox exists. For their addresses, PricklyMails returns valid, with a capped score and the reason shown, and bills every check you asked for, mailbox test included. We do not know how ZeroBounce bills that case: its pages do not say.

Catch-all domains

On a domain that accepts every address, ZeroBounce says it can resolve some addresses to valid or invalid during standard validation, and offers a Verify+ option to go further as well as AI scoring at one credit per address; the rest come back as "catch-all". PricklyMails does not resolve them: the address comes back "risky", with a "review" recommendation and the reason shown. Catch-all detection comes with the Pro plan and above. The guide on catch-all domains explains the approach we chose.

Your data

Both services say they process your data in the European Union. The difference is what stays, and for how long. ZeroBounce deletes uploaded files and their results 30 days after upload. PricklyMails never writes the address to disk: it stays in memory until its verification ends, 96 hours at most. All that remains afterward is a fingerprint, computed with a secret key only we hold, which does not let anyone read the address back. That fingerprint is kept with the result for as long as your account exists, for your history and for the verification cache shared across customers.

What ZeroBounce offers on top

ZeroBounce ONE bundles other deliverability tools: inbox placement tests, blacklist monitoring, DMARC monitoring, an email finder, and warmup. PricklyMails focuses on verifying addresses, through the dashboard, the API, webhooks, or an AI agent.

Which one to choose

ZeroBounce is the better fit if you want:

• A full deliverability suite from a single vendor.
• Unknown results that cost nothing at all.
• A decision on more of your catch-all addresses.
• Large one-off volumes without a subscription.

PricklyMails is the better fit if you want:

• To pay check by check.
• A subscription sized for small volumes, from €8 a month.
• Tokens that never expire, without a subscription to maintain.
• No address ever written to disk.
• To connect an AI agent over OAuth, without copying a key.

The simplest way to compare is still to try both on a few addresses from your own list: create an account and get free tokens on signup, no credit card required.
