Cheapest bulk email verifier: price to verify 100,000 emails

What is the cheapest way to verify 100,000 emails?

What it is

Email verification with a real SMTP mailbox check: each address comes back valid, risky or invalid with a reason. Includes an email finder on Pro and up.

Price per check

Starter $9/mo for 2,500 ($3.60 per 1,000); Pro $39/mo, 100,000 a month at full speed ($0.39 per 1,000 when used), then slower, never cut off. Business $99/mo with 300,000 at full speed; Agency $249/mo with 750,000 at full speed.

One-time packs

10,000 for $15 ($1.50 per 1,000); 25,000 for $29 ($1.16 per 1,000); 50,000 for $49 ($0.98 per 1,000); 100,000 for $79 ($0.79 per 1,000); 250,000 for $169 ($0.68 per 1,000). Credits never expire, run at standard speed, CSV verification only (no API or finder).

Free checks

First 100 email checks free with a Google sign-in, no card, once per account. Single checks on the free email checker need no account.

Billing

Monthly subscription, cancel anytime (yearly billing optional). One-time packs are listed above. Starter allowances reset monthly and do not roll over.

Speed today

One sending IP today, shared by every customer: about 13,000 mailbox checks a day in the standard lane. Bad syntax, dead domains and disposable addresses return at once; a list of 100,000 takes days, not hours, and each job shows its estimated finish time.

Catch-all handling

Catch-all (accept-all) addresses stay risky, never valid, and are graded higher, medium or lower likelihood with the reasons. Anything a mail server does not confirm is risky.

API and MCP

REST API on Pro, Business and Agency (Pro includes 10,000 calls a month, then $1.50 per 1,000). Remote MCP server with 6 tools for Claude, ChatGPT, Cursor and VS Code. No API on Starter.

Integrations

Connects to Instantly, Smartlead, HubSpot and Mailchimp by API key: verifies a campaign or list and tags each contact with its result. CSV in and out for any other tool.

Phone

Free phone format checks (country, type range). Live carrier and line-type lookups come with Pro + Phone at $49.99/mo (5,000 a month). It never says a number is in service.

What it does not do

No sending, warmup or inbox placement tests. No published accuracy benchmark against other verifiers. Catch-all domains, Yahoo and AOL cannot be confirmed, and Outlook.com and Hotmail mailboxes are not probed while Microsoft refuses checks from our server's network: all of these come back risky, never valid.

Which one should you pick?

• 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 want a low price on a one-off clean of a small or medium list, with pay-as-you-go credits that never expire.

• Pick MillionVerifier if you clean a very large list once in a while: 1,000,000 credits are $449 one-time, never expire, and there is no subscription to cancel.

• Pick EmailListVerify if you verify a steady 5,000 to 10,000 addresses a month ($16 a month for 5,000), or want pay-as-you-go credits that never expire.

• Pick Emailable if you want 250 free credits to test with and credits that never expire.

• Pick Bouncer if you also want inbox placement and blocklist tests from the same vendor (its Deliverability Kit is a separate plan).

• Pick ZeroBounce if you will use what its subscription bundles (inbox placement tests, blacklist monitoring, warmup), or want a free allowance that refills every month.

• Pick Kickbox if you want unknown results refunded as credits, or deliverability consulting alongside verification.

• Pick NeverBounce if you want verification synced inside many marketing tools: its pricing page lists 80+ integrations.

• Pick Clearout if you pay yearly and also want an email finder and prospecting on the same credit balance.

• Pick Hunter if you want to find, verify and send from one tool rather than buy a verifier on its own.

How we compared

On 27 October 2026 we read each vendor's pricing page at 100,000 credits and list it under each tool. Where only one of a plan or a pack is published, that is the one ranked. 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.

Common questions

What is the cheapest way to verify 100,000 emails?

By published prices on 27 October 2026: SimpleVerifier Pro at $39 for a month, then DeBounce ($124.20 a month or $135 one-time), MillionVerifier ($149 one-time) and EmailListVerify ($168 a month).

Is a monthly plan or a credit pack cheaper for bulk verification?

A pack suits one clean you will not repeat, because the credits never expire. A flat monthly plan costs less when you verify every month or re-check the same list, because each pass on a pack is bought again.

Do duplicates and unknown results cost credits?

It varies: DeBounce removes duplicates free, ZeroBounce does not charge for unknowns, and Kickbox refunds unknowns as credits (their pricing pages). On SimpleVerifier, duplicates and addresses we cannot check are free.

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.
