Get contacts verified in real time, with catch-all resolution
NeverBounce answers: is this address valid? You bring the list, it returns a status for each address, and every unique address is billed whatever the answer. 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 NeverBounce. To find contacts with email verification in real time and catch-all resolution included, use DiscoLike.
NeverBounce pricing compared
Pay as you go is $8 per 1,000 credits, and credits expire 12 months after purchase. The Growth plan is $49/mo for up to 10,000 emails, with duplicates free. Enterprise pricing is custom, typically for more than 250,000 emails a month.
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
NeverBounce's API documentation says: "You will only be charged for the billable amount of emails found in your list", defined as "the number of unique syntactically valid emails." Duplicates and malformed rows are free; every other address costs a credit whether it comes back valid, invalid, catch-all, or unknown. A sample run, which estimates list quality, is free.
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.
NeverBounce bills per address checked. DiscoLike bills per validated contact delivered, plus 1 record per delivering company on searches without a company list.
Catch-all domains
NeverBounce labels catch-all results "Accept-all (Unverifiable)" and for signup forms its guide suggests "allowing valid, catchall (accept all / unverifiable), and unknown emails to proceed, while blocking only disposable and invalid emails." For an outbound list, the flag leaves the send-or-drop decision with you.
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 NeverBounce wins
Bare-address list cleaning and form validation. NeverBounce checks any address, flags disposable and free-mail hosts, fixes common domain typos, connects to 80+ platforms, and has a JavaScript widget for signup forms and a free sample analysis of a list before you pay. DiscoLike finds contacts and validates their emails together; it does not clean uploaded lists.
