Email verifiers with free credits: 14 compared

Which one should you pick?

• Pick Bounceless if you verify under about 20,000 addresses a month, want credits that never expire, or want sender health and inbox placement tools in the same account.

• Pick Emailable if you want credits that never expire, a larger free allowance on signup, or a verifier with SOC 2 Type II on its pricing page.

• Pick Scrubby if your list is full of catch-all or gateway-protected addresses and you will pay for each one to be resolved, or wait up to 72 hours for Deep Verification.

• Pick SimpleVerifier if you verify or re-check lists every month and want one flat monthly price instead of credits, with catch-all addresses kept risky rather than marked valid.

  Skip SimpleVerifier if you want the lowest price for one small list, where another vendor's pack can cost less (cost by list size); you need your data processed only inside the EU (our service providers process data in several countries, including the US); or your list is mostly Outlook.com, Hotmail or Live addresses, which Microsoft currently won't let us confirm, so they come back risky (why).

• Pick DeBounce if you clean small or one-off lists and want credits that never expire, with no subscription to cancel.

• Pick EmailListVerify if you verify 10,000 addresses a month or fewer, steadily.

• Pick MillionVerifier if you clean one very large list now and then and don't re-check it often.

• Pick Bouncer if EU-only data storage is a requirement, or you want its toxicity checks and form protection.

• Pick Clearout if you verify under about 10,000 addresses a month, pay yearly, and want its form guard or many native integrations.

• Pick Kickbox if you need a vendor with published SOC II certification or deliverability consulting from the same team.

• Pick ZeroBounce if you want inbox placement tests, blacklist monitoring and warmup in the same account as verification.

• Pick EmailVerify.io if you verify up to about 15,000 addresses a month and want a plan that costs less than ours at that size.

• Pick Verimail if you verify up to about 10,000 addresses a month, or clean a list now and then and want credits that never expire.

• Pick NeverBounce if you need verification wired into many marketing tools through native integrations, or you already run on ZoomInfo.

How we compared

We took each vendor's stated allowance for a new account from our dated vendor data and list the vendor page under each row. A larger allowance is not a better verifier: use it to run a sample of your own list, including addresses you know are dead, then compare the results. We did not run an accuracy benchmark, so nothing here ranks accuracy: test a shortlist on a sample of your own list, including addresses you know are dead.

Each tool in a few lines

1. 1. Bounceless

   Best for: Small monthly volumes and a monthly free allowance

   • A work email gets 1,000 free credits every month, against our first 100 free checks.
   • Its pricing page says credits never expire, on credit packs and subscriptions alike, and unconfirmed results are not billed.
   • Watch out: The allowance is a credit count, so 100,000 a month is $99 on Business and $159 as a pack, and every re-check of the same list spends credits again.

2. 2. Emailable

   Best for: Buyers who want credits that never expire and a larger signup allowance

   • Credits never expire, and on a subscription unused credits roll into the next billing period.
   • Credits spent on Unknown results and duplicates are returned when a list finishes.
   • Watch out: It is priced per credit, so the bill scales with the list: 100,000 a month is $357 even with the subscription discount, and every re-check is billed again.

3. 3. Scrubby

   Best for: Catch-all and gateway-protected addresses, resolved per address

   • Its pricing page says Quick Verification (1 credit) confirms deliverability on catch-all and SEG-protected domains, and Deep Verification (3 credits) sends a real email to each address and watches how servers respond for 72 hours.
   • Unused credits on monthly plans roll over while the subscription is active, and PayGo credits never expire.
   • Watch out: The plans stop at 100,000 credits for $497 a month, Deep Verification spends 3 credits per address, and its pricing page says all purchases are final, with no refunds for unused credits.

4. 4. SimpleVerifier(our tool)

   Best for: Lists checked every month, re-checks and campaign tools it connects to

   • Catch-all addresses come back risky, never guessed valid
   • Connects to Instantly, Smartlead, HubSpot and Mailchimp by API key
   • Watch out: The free allowance is a one-time 100 checks, not a monthly refill
   • Watch out: Starter has no API and its allowance does not roll over; 10,000 a month needs Pro

5. 5. DeBounce

   Best for: Small and one-off lists on credits that never expire

   • Pay-as-you-go credits never expire, and every feature is included on every plan, API included.
   • Duplicates are removed for free, so you never pay twice for the same address in one list.
   • Watch out: Every option is metered by the credit, so every pass over the list is billed again — the cost scales with how often you clean, not just how much.

6. 6. EmailListVerify

   Best for: Steady lists of 5,000 to 10,000 a month

   • Smaller lists cost less there: $16 a month for 5,000 and $25 a month for 10,000, both under our $39.
   • Pay-as-you-go starts at $5 for 1,000 and those credits never expire.
   • Watch out: The allowance is the ceiling — a list past it pushes you up the tiers, and a 100,000-address clean is a $186 pay-as-you-go job.

7. 7. MillionVerifier

   Best for: Very large one-off cleans

   • For a single very large clean its published packs are low per address: 1,000,000 credits for $449 and 10,000,000 for $2,599.
   • Credits never expire, so a pack bought for one clean covers later ones too.
   • Watch out: Every pass is a fresh purchase, so a list you re-check monthly is bought again each time.

   Checked November 2, 2026: MillionVerifier pricing

8. 8. Bouncer

   Best for: Teams that also want inbox placement and blocklist tests

   • Bouncer says data is stored only in EU AWS data centres and that it is GDPR compliant by design.
   • It sells a Toxicity Check, a Deliverability Kit and Bouncer Shield for real-time form checks.
   • Watch out: Credit-based pricing means the second pass over a list costs the same as the first.

9. 9. Clearout

   Best for: Buyers who pay yearly and want a finder and form guard

   • Its yearly price is a little under ours: the 10,000-a-month Pro plan is $384 a year ($32 a month), against our $390 a year.
   • Its integrations page lists a long catalogue of apps, including HubSpot, Salesforce, Mailchimp, Gravity Forms and Make.
   • Watch out: The monthly-billed price is far above the annual one — 10,000 a month is $58 billed monthly against $32 a month billed yearly — so the low headline needs a year's commitment.

10. 10. Kickbox

    Best for: Senders who want deliverability consulting beside verification

    • Kickbox says it is SOC II certified and GDPR-compliant, with verification and support in both the US and the EU.
    • Unknown results are refunded as credits.
    • Watch out: Verification is billed per email, so cleaning a large list is a variable cost you cannot forecast from the plan price.

11. 11. ZeroBounce

    Best for: Teams that want a deliverability suite in one plan

    • ZeroBounce ONE ($99 a month) bundles 10,000 validations with 10,000 email finds, 100 inbox placement tests, blacklist monitoring and 250 warmup seeds.
    • Credits never expire while a ZeroBounce ONE subscription is active, and unknown results are not charged.
    • Watch out: Credits are the unit, so the bill scales with list size and a re-verification of the same list costs full price again.

12. 12. EmailVerify.io

    Best for: Up to about 15,000 a month

    • Its entry plan is $25 a month for 15,000 credits, or $240 a year, under a month of Pro for lists that size.
    • Every account gets 100 free credits each month, renewing for as long as the account exists, against our first 100 free checks.
    • Watch out: The allowance is a credit count, so 100,000 a month is $149 on a plan or $199 as a pack, and subscription credits reset each cycle below its 500,000-credit tiers.

13. 13. Verimail

    Best for: Up to about 10,000 a month

    • Its Starter plan is $15 a month for 10,000 credits, and packs start at $4 for 1,000.
    • Its pricing page says unknowns, duplicates and syntax errors are never charged, and pack credits never expire.
    • Watch out: It has no plan between 10,000 and 100,000 a month, so 25,000 a month is a $40 pack or the $79 Professional plan, and 1,000,000 a month is $299.

    Checked November 5, 2026: Verimail pricing and FAQ

14. 14. NeverBounce

    Best for: Teams that want verification synced into many marketing tools

    • Its pricing page says it works with 80+ integrations, including Zapier, n8n, HubSpot and Mailchimp.
    • Sync cleans lists inside connected tools automatically, and Growth only bills new, unique emails.
    • Watch out: Credits expire, so an allowance bought for a campaign that slipped a quarter is simply gone.

Common questions

Which email verifier gives the most free credits?

Bounceless gives 1,000 credits a month with a work email, no card. Among one-time allowances, Emailable gives 250 credits on signup and most others give 100.

Are free credits enough to test a verifier?

Enough to run a small sample, not a full list. Use a sample that includes some addresses you know are dead and some real ones, then compare how each tool labels them, especially catch-all and risky results.

Do I need a card to use free credits?

It varies by vendor; where a vendor's page says no card is needed we say so in its row. SimpleVerifier needs a Google sign-in and no card.

Is the cheapest verifier the most accurate?

We did not run an accuracy benchmark, so nothing here ranks accuracy: test a shortlist on a sample of your own list, including addresses you know are dead.
