ZeroBounce Pricing and Catch-All Visuals

Use these visuals to connect ZeroBounce's published credit table with its second-pass catch-all workflow.

Pricing and Total Cost

For teams that mostly need to clean lists or verify addresses through an API, the biggest difference is not whether both tools can validate emails. They can. The difference is what you are paying for around the validation call. ZeroBounce prices verification as part of a larger deliverability platform. VeriMails prices verification as the primary product.

Credit-pack costs at common volumes

ZeroBounce also publishes a $39 minimum purchase for 2,000 credits. ZeroBounce ONE is a separate subscription at $99/month, or $79/month when billed annually, with 10,000 monthly verification credits and other deliverability tools.

ZeroBounce one-time credit pricing tiers

Computed pack costs are rounded to the nearest dollar where the pricing table publishes a per-credit figure. ZeroBounce also states that it does not charge for duplicate addresses or unknown results, and that credits never expire.

VeriMails credit pricing

VeriMails credits never expire. New accounts receive 100 free credits on signup.

Catch-all Handling

ZeroBounce no longer looks like a simple binary catch-all workflow. ZeroBounce now describes Verify+, a second phase that runs when at least 10 catch-all emails appear in a bulk validation. ZeroBounce says the additional phase can reclassify some catch-alls as valid or invalid, while the remainder stay catch-all. The same guidance says this can take up to 48 hours, and include a caution that catch-all domains are among the hardest addresses to validate.

VeriMails keeps the signal simpler: detect catch-all domains during verification and return that flag clearly. That is useful when the operational decision is segmentation. A cold outreach team may exclude catch-all addresses from high-reputation sends, test them in smaller batches, or route them to a different risk policy.

API and Developer Experience

ZeroBounce's API is mature and well documented. The single email validator has default, US, and EU URLs; returns structured fields such as status, sub_status, domain, MX record, SMTP provider, and optional appended data; and the API reference says most domains return in 1 to 5 seconds, while the endpoint can take 1 to 30 seconds depending on mail server behavior. The same API reference lists a high validation rate limit of 80,000 requests in 10 seconds, with 100,000 for ZeroBounce ONE customers.

VeriMails is less expansive, but easier to reason about for a verification-only build. The API and bulk workflow are priced from the same credit pool, and the output focuses on deliverability status, role/disposable risk, and catch-all detection. If you need enrichment fields and deliverability monitoring in the same vendor account, ZeroBounce has the broader platform. If you want a lower-cost verification layer inside your signup flow, CRM cleanup, or cold email prep, VeriMails is the leaner fit.

Who Should Choose Which?

Run the Next Check in VeriMails

After comparing pricing, credits, API behavior, and catch-all handling, the practical next step is to verify a real sample from your own list.

Verification Accuracy

Both VeriMails and ZeroBounce can help reduce bad addresses before a campaign. The difference is how clearly the result fits your next send: VeriMails keeps valid, invalid, disposable, role-based, catch-all, and unknown rows separate for decision-making.

Use a recent sample from your own CRM, not a perfect test list. The addresses that matter are the ones you plan to mail this week: old leads, imported contacts, role inboxes, catch-all domains, and records from mixed sources.

Who VeriMails Is Best For

Choose VeriMails when verification is the job and you want the result before the send.

• You already have a list and need to clean it before a campaign.
• You want prepaid verification credits that never expire.
• You need API and CSV verification without paying for a larger sales platform.
