The cheapest email verification, by list size
The cheapest email verifier depends on two things: how big the list is and how often you check it. Credit packs are usually cheapest for one small pass; flat monthly plans are usually cheapest for large or repeated lists. For one list of 10,000, the lowest published price we found is Bulk Email Checker at $9.95 (read 4 Nov 2026); SimpleVerifier costs $15 (a one-time pack of 10,000 email checks that never expires). The tables below show every vendor we price, including the ones that cost less than we do.
Every figure here is read from the vendor's own pricing page and the date it was read is on each comparison page. For a size not listed, the verification cost calculator prices any volume across the same vendors.
For one list of 2,500, the lowest published price we found is Listclean at $5 (read 4 Nov 2026); SimpleVerifier costs $9 (one month of Starter, 2,500 emails a month). For one list of 100,000, the lowest published price we found is Listclean at $35 (read 4 Nov 2026); SimpleVerifier costs $39 (one month of Pro).

Each vendor's lowest published route for one list of that size, read from its own pricing page. Ours is the cheaper of one month of the smallest plan that covers it and a one-time pack, where packs are sold. Where a vendor is below our figure, it costs less for that job. Vendor prices read 12 Oct 2026 to 5 Nov 2026. Each vendor links to its comparison page, which records the date its prices were read. Check their site for current pricing before you buy.
SimpleVerifier facts: prices, packs and limits
- 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.
SimpleVerifier facts from our pricing page and product. Last updated .
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.

Why the cheapest headline price is often not the cheapest bill
A low per-1,000 rate is usually the largest pack. On a small list you pay the small-pack rate, which can be several times higher. Credits that expire turn an unused balance into a cost, and a credit pack is bought again for every re-check of the same list.
A monthly plan has the opposite problem: if you verify once a year, you pay for months you don't use. Starter and Pro cancel anytime, so one month for one list is a real option.
Cheap is only cheap if the results are right
A verifier that only checks syntax and MX records will mark dead mailboxes as valid, and the bounces cost more than the verification saved. Test before you buy: invent an address at a real domain and check it on each tool. A real mailbox check returns invalid or risky; a syntax-only check returns valid.
Common questions
- What is the cheapest email verification service?
- It depends on the list. For one list of 10,000, the lowest published price we found is Bulk Email Checker at $9.95 (read 4 Nov 2026); SimpleVerifier costs $15 (a one-time pack of 10,000 email checks that never expires). For lists you re-check every month, a flat plan usually costs less than buying credits again.
- Is a credit pack or a subscription cheaper?
- For one pass over a small list, a credit pack often is. For a list you verify every month, or a large one, a flat monthly plan usually is. The tables on this page show both cases.
- Can I try SimpleVerifier free?
- Yes. The first 100 checks are free with a Google sign-in, no card.
Compare it on your own list
Pro is $39 a month and never cuts you off: the first 100,000 emails a month run at full speed, then big lists run slower. CSV uploads, the API (10,000 calls a month, then $1.50 per 1,000), the Google Sheets add-on and the email finder are included, and you can cancel any time. For smaller volumes, Starter is $9 a month for 2,500 emails a month.
The first 100 email checks are free with a Google sign-in, no card, on the same engine the paid plans use.
