What is the cheapest way to verify 100,000 emails?
On SimpleVerifier, Pro is $29.99 a month and runs 100,000 emails at full speed, then keeps going in a slower lane. It is a monthly subscription you can cancel; there are no one-time packs. Other vendors' prices for 100,000 are in the table with the date they were read. The first 100 checks are free.
| 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); Growth $19/mo for 10,000 ($1.90 per 1,000); Pro $29.99/mo, 100,000 a month at full speed ($0.30 per 1,000 when used), then slower, never cut off. Business $99/mo, Agency $249/mo. |
| 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). No one-time credit packs. Starter and Growth allowances reset monthly and do not roll over. |
| 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 or Growth. |
| 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 are a $20/mo add-on (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. Outlook.com, Hotmail and iCloud mailboxes are not probed and come back risky. |

Common questions
- What is the cheapest way to verify 100,000 emails?
- By published prices on 27 October 2026: SimpleVerifier Pro at $29.99 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.
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.
