Get contacts verified in real time, with catch-all resolution
ZeroBounce answers: is this address valid? You bring the address, it returns a status, and the check is billed whether the answer is good or bad. If the answer is invalid or catch-all, you still have no one to email.
DiscoLike finds the contact and verifies the email in real time, with catch-all resolution included. Describe who you want to reach at your target companies. Only validated contacts with an email reach your results. You pay for delivered contacts plus 1 record per company that delivers a validated contact when you search without your own company list. This avoids buying upstream contact data and then paying to check unusable addresses.
To check addresses you already have, use ZeroBounce. To find contacts with email verification in real time and catch-all resolution included, use DiscoLike.
ZeroBounce pricing compared
Pay as you go starts at $39 for 2,000 credits ($19.50 per 1,000) and falls to $2.70 per 1,000 at 10 million. Subscriptions start at $99/mo for 10,000 credits, and the free plan includes 100 credits a month. Email Finder uses 20 credits per successful search.
DiscoLike has Pay as you go and subscriptions at $99 to $1,599/mo in credits. Validated contacts cost $25/1,000 on Pay as you go, $17.50 on Starter, $15 on Pro, $12.50 on Team, and $10 on Company and Enterprise. Searching without your own company list adds 1 record per company that delivers a validated contact, at the plan rate. Validated and Validated (catch-all resolved) cost the same. Every delivery is billed, including repeats.
What you pay for
ZeroBounce's pricing page says: "You'll use one credit per email address verified", and that it will "never charge you for 'unknown' results." Invalid, catch-all, spam trap, and abuse results each use a credit, which is fair for a hygiene tool: the answer is what you bought.
You pay only for validated contacts with an email: 5 records at your plan rate, with a $10 per 1,000 floor ($10 to $17.50 on subscriptions, $25 on Pay as you go), plus 1 record per company that delivers a validated contact when you search without your own company list. Validated and Validated (catch-all resolved) cost the same. Every delivery is billed, including repeats. Validation is included only with contacts found through DiscoLike search. Company discovery retrievals have a separate reuse window of 24 hours on Pay as you go or 30 days on subscriptions; that window does not apply to contact deliveries.
ZeroBounce sells the verdict. DiscoLike delivers the contact with email verification in real time and catch-all resolution included.
Catch-all domains
ZeroBounce returns some catch-all addresses as valid when the domain is on its accept_all allow-list, based on its long-term sending data. For the rest, its documentation says they "are impossible to validate without sending a real email" and suggests segmenting them. AI Scoring adds a likelihood score for one more credit.
A catch-all domain accepts mail for any address, so acceptance by the domain alone does not prove a mailbox exists. Validated (catch-all resolved) means the mailbox was verified in real time. The domain accepts all mail; we resolved the catch-all and confirmed this address exists. Another verifier may report catch-all or unknown; you do not need to re-check it. Contacts appear only after validation. DiscoLike runs its own email engine rather than reselling a verification API.
Where ZeroBounce wins
List hygiene at scale. ZeroBounce returns a detailed status set (spam traps, abuse, role-based, disposable, do_not_mail), activity data, and typo suggestions, alongside warmup, inbox placement, and blacklist monitoring. It has 100 free credits a month and per-address prices that fall to $2.70 per 1,000 at volume. If you need to clean an existing list of addresses before a send, it is built for that and DiscoLike is not.

ZeroBounce vs NeverBounce: how do they bill?

Does ZeroBounce resolve catch-all emails?
Partly. Catch-alls on domains in its accept_all allow-list are returned as valid; others are flagged, with an optional paid score. DiscoLike delivers only validated contacts. Validated (catch-all resolved) means the mailbox was verified in real time. The domain accepts all mail; we resolved the catch-all and confirmed this address exists.
Can I upload a list of addresses to DiscoLike for cleaning?
No. DiscoLike includes validation only with contacts found through DiscoLike contact search. For bare-address hygiene, use a verifier such as ZeroBounce.
How should I compare the cost?
Divide what you paid by the number of addresses you can actually send to.
