How to choose

  1. Price per 10,000 checks

    Price the pack you would really buy, not the smallest one. Check whether credits expire and whether a subscription changes the rate.

  2. Catch-all and unknown results

    A catch-all domain accepts mail to any address, whether or not that mailbox exists. See how each tool reports these and whether unknowns cost a credit.

  3. Upload, API and integrations

    Most take a file upload and an API call. Check for a direct link to the CRM or email tool you already use.

  4. What you get back

    A file of results to clean up yourself, or a clean list already in your CRM. The second saves a step on every list.

The tools

  1. 1. NeverBounce

    Best for: Real-time checks through an API

    Verifies lists and single addresses through its API, with code samples for PHP, Node, Python, Go, Ruby, .NET and Java. Each address comes back valid, invalid, disposable, catchall or unknown. Pay-as-you-go credits expire 12 months after purchase.

    Price
    $8 per 1,000 credits; Growth $49 a month for up to 10,000
    Keep in mind
    Catch-all addresses come back as catchall, which it calls unverifiable.

    Operelio vs NeverBounce

  2. 2. Bouncer

    Best for: Verification plus a deliverability kit

    Each address comes back deliverable, undeliverable, risky or unknown. Bouncer doesn't charge for unknown results or for duplicates in a list. 100 free credits to start.

    Price
    $8 for 1,000 checks; 10,000 for $60
    Keep in mind
    Catch-all addresses come back risky, so you decide whether to send.
  3. 3. Clearout

    Best for: Resolving catch-all addresses

    Deep Verify tries to resolve catch-all and gateway-protected addresses into valid or invalid. Unknown results cost nothing, credits never expire, and new accounts get 100 free credits.

    Price
    From $40 for 5,000 credits; 10,000 for $65
    Keep in mind
    Deep Verify is charged by its Safe to Send outcome, not one flat credit.
  4. 4. Kickbox

    Best for: Small packs to start

    Each address comes back deliverable, undeliverable, risky or unknown, with a reason. If Kickbox can't give a definitive result, it refunds the credit.

    Price
    100 free, 500 for $5; 10,000 for $70
    Keep in mind
    Accept-all, disposable and role addresses are all grouped as risky.
  5. 5. Emailable

    Best for: Monthly credits at a lower rate

    10,000 for $60, or $51 a month subscribed
    Keep in mind
    The smallest purchase is 5,000 credits.

  7. 7. Operelio

    Our tool

    Best for: Lead lists that go into a CRM

    Verification sits inside cleanup and the CRM push. Each row costs one credit, even when a catch-all, risky or unknown address gets a deeper second check. Then the list goes to HubSpot, Salesforce or Pipedrive.

    Price
    Starter from $39 a month, with 1,000 credits; 10,000 more for $100
    Keep in mind
    No verification on the Free plan, which runs the free checks only.

Frequently asked questions

What is ZeroBounce?

An email verification and deliverability platform. It checks whether each address can receive mail, one credit per address, and adds AI scoring, an email finder, warmup, inbox placement tests and blacklist monitoring.

How does ZeroBounce work?

You upload a list or call its API. Each address comes back with a status such as valid, invalid, catch-all, unknown, spamtrap, abuse or do_not_mail.

Is ZeroBounce worth it?

If you also want its deliverability tools, such as warmup and inbox placement tests, yes. For verification alone, Bouncer, Clearout, Kickbox, Emailable and MillionVerifier all charge less for 10,000 checks, from $39 to $70.

Which is better, Emailable or ZeroBounce?

For verification alone, Emailable costs less: $60 for 10,000 credits against ZeroBounce's $129, and neither charges for unknown results. ZeroBounce adds AI scoring, an email finder and deliverability tools.

What does catch-all mean in ZeroBounce?

A catch-all domain accepts mail to any address, whether or not that mailbox exists. ZeroBounce marks these catch-all, because they can't be validated without sending a real email, and suggests sending to them as a separate group.
