Verify an email list free
You can verify the first 100 addresses of an email list free on SimpleVerifier: sign in with Google, paste the addresses or upload a CSV, and each one gets a syntax check, an MX lookup and a live mailbox check where the provider allows it, with valid, risky and invalid results to download. No card is needed. Larger lists continue on a plan from $9 a month.
The free checks run on the same engine as the paid plans, so what you see on 100 addresses is what you would get on the whole list. Each address you check uses one; duplicates in the same file are not counted.
If you only want to see what is in a file before checking anything, the email list health check reads a CSV in your browser and reports duplicates, role addresses, free-mail share and broken syntax, without sending the addresses anywhere and without an account.

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. 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.
By continuing you agree to our Terms and Privacy Policy.
What the free checks include
Every check: syntax and normalisation, the domain's MX records, 9,913 disposable domains, role addresses such as info@ and sales@, catch-all detection and, where the mail server allows it, an SMTP conversation that asks whether the mailbox exists without sending an email.
Some large consumer providers accept every address, and Microsoft is currently refusing checks from our server's network. Addresses there are returned as risky with the reason, not as valid, so the valid file only holds addresses a server actually confirmed.

After the free checks
Starter is $9 a month for 2,500 emails a month; unused emails don't roll over. Pro is $39 a month, never cut off: the first 100,000 emails a month run at full speed, then big lists run slower, and includes the API (10,000 calls a month included, then $1.50 per 1,000) and the email finder. Every plan is monthly, cancels anytime, and you can try 100 checks free before you pay; fees are non-refundable once charged.
Common questions
- Can I verify an email list for free?
- Yes, the first 100 addresses. Sign in with Google, paste or upload the list, and those addresses get the full check with results to download. No card is needed.
- Are the free checks the same as the paid ones?
- Yes. They run on the same engine with the same mailbox check, and return the same valid, risky and invalid results.
- What happens to the rest of my list?
- The first 100 addresses are checked and the rest wait. If you choose a plan, the rest of the list is checked on it; if not, nothing else happens and you are not charged.
- Do you send an email to the addresses?
- No. The mailbox check talks to the recipient's mail server and stops before any message is sent.
Check 100 addresses free
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.
