How much does it cost to verify 100,000 emails?
On SimpleVerifier Pro is $39 a month and covers 100,000 checks at full speed, with no per-email fee. Other vendors' published prices for 100,000 addresses run from $35 (Listclean) to $1,699 (Enrichley). Prices differ a lot by vendor and change often, so read the live pages before you buy.
What 100,000 costs on SimpleVerifier
One month of Pro at $39: the first 100,000 a month run at full speed, then slower, never cut off. A list of 100,000 fits inside that volume, so it runs at full speed and the price does not change if you re-check the list.
That is $0.39 per 1,000 if you use the whole allowance. One-time packs from $15 for 10,000 checks up to $169 for 250,000; the credits never expire and run at standard speed (CSV verification only).

What the price leaves out
Expiry, whether catch-all and unknown results are charged, minimum purchases and speed all change the real cost. Ask each vendor three questions: does an unused credit expire, is a catch-all result charged, and how long will 100,000 rows take.
How long 100,000 takes
No verifier is instant on a big list, because each check is a conversation with another company's mail server. Each job shows an estimated finish time before you commit; see how long bulk verification takes.
What SimpleVerifier costs and what it cannot confirm
- 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
- Unlimited email verification on Pro means the first 100,000 checks a month at full speed, then slower, never cut off. It is not instant: checks are paced and capacity is shared by all customers, so small lists finish sooner, a very large list queues and can take days rather than hours, and every job shows its estimated finish time. Bad syntax, dead domains and disposable addresses return at once.
- 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 7 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.
- Privacy and GDPR
- Data processing agreement countersigned on request (/dpa). Results files deleted 7 days after a list is submitted; confirmed results cached by address for 14 days. Lists are not used for marketing, sold or shared. Verification runs on a US server. No GDPR certification is claimed.
- 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.

Related questions
- Is 100,000 emails one month of Pro?
- Yes. Pro is $39 a month and its full-speed volume is 100,000 checks, so a list of 100,000 fits in one month.
- Can another vendor cost less for 100,000?
- Yes, some credit-pack vendors publish a lower price for a single pass at this size. The cost page lists them with the date each price was read.
- Do I pay again to re-check the list?
- Not on a SimpleVerifier plan. A re-check is not a new bill, only a new pass at the same flat price.

Figures marked as ours come from SimpleVerifier’s own dated tests on made-up addresses, published with their data on the research page. No customer data is used, and we publish no accuracy percentage because we have no independent measurement to back one.
Do it now
Test it on a real address first
Type any address. It gets the same check the paid plans run: syntax, the domain’s mail servers and, where the provider allows it, a live mailbox check. Nothing is sent to the address.
Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.
Have a list? Sign in with Google and the first 100 addresses are checked free, with results to download. No card.
