Email Verification: SimpleVerifier against per-credit tools
Prices read from each vendor's own pricing page between 30 Oct 2026 and 3 Nov 2026: the cheapest published way to verify 10,000 emails in one month, billed monthly. Per year is the vendor's published annual price where it applies to that plan, otherwise 12 months at the monthly price; several vendors discount annual billing. Each is compared with 12 months of ours at monthly billing ($468).

SimpleVerifier checks each address with a real SMTP mailbox check (valid, risky or invalid, with a reason). Built for cold emailers, marketers and agencies cleaning lists before they send. Monthly plans: $9 for 2,500 emails, or Pro at $39 with 100,000 a month at full speed, never cut off. 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); 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.

Built for the list you send next
Clean the list before it costs you a domain
You have a list and a campaign waiting. SimpleVerifier tells you which addresses will bounce, says plainly what it can’t confirm, and costs the same every month you re-check.
Protect your sender
Bounces burn sending domains. Catch them first.
Every hard bounce counts against the domain you send from, and enough of them get campaigns paused. Each address gets a live SMTP mailbox check, and your list comes back in three piles, so dead addresses never reach your sequence.
Send
Mailbox confirmed
Your call
Catch-all, role, unconfirmed
Remove
Dead, disposable, no mail server
No fake valids
We never call a guess valid
Catch-all domains, Yahoo, AOL and mailboxes a server won’t confirm come back risky, with the reason. You decide what to send.
A “valid” that bounces costs you more than a “risky” you skip.
Readable results
Every row tells you why
Your export keeps your columns and adds a status plus the reason, so you can defend every cut to a client.

Verify where your campaigns already live
Connect by API key, pick a campaign or list, and every contact comes back tagged with its result. CSV in and out for any other tool.
Lists go stale as people change jobs. A monthly plan means checking again before the next campaign isn’t a new bill, and there are no credits to run out mid-list.

SimpleVerifier checks whether email addresses exist before you send. It runs a real SMTP mailbox check on each address and returns valid, risky or invalid with a reason; catch-all addresses stay risky, never valid. Plans start at $9 a month for 2,500 emails a month; Pro is $39 a month with the first 100,000 checks a month at full speed, then slower, never cut off. The first 100 checks are free with a Google sign-in, no card.
How does email verification work?
Verification runs in layers: a syntax check on the address, an MX lookup to confirm the domain has mail servers, then an SMTP conversation with that server asking whether the specific mailbox exists. Nothing is ever delivered — the connection names the address, reads the response and closes.
Is there a limit on how many emails I can verify?
Pro never cuts you off. It is $39 a month with no credits and nothing to expire: the first 100,000 emails each month run at full speed, then lists of 2,000 rows or more run in a slower shared lane. Business ($99) and Agency ($249) run 300,000 and 750,000 a month at full speed. For a small list there is Starter at $9 a month for 2,500 emails a month; its allowance resets each billing month and unused emails don't roll over. Checks are paced so mail servers keep answering, so a very large list queues rather than being rejected (the job card shows an ETA), and confirmed results are cached for 14 days so an overlapping list returns instantly. Re-checking an address counts as a check, the same as a first check.
What is the difference between valid, risky and invalid?
Valid means the recipient's mail server confirmed the mailbox exists. Invalid means it confirmed it does not, or the syntax is broken, or the domain has no mail server, or the domain is a known disposable provider. Risky means the domain works but the mailbox could not be confirmed — usually a catch-all domain that accepts every address. Anything unconfirmed is reported as risky, never as valid.
Why does my address come back risky instead of valid?
Because the mailbox genuinely could not be confirmed. The most common reason is a catch-all domain, where the mail server accepts every address whether it exists or not, so no verifier can tell a real mailbox from an invented one. Greylisting and servers that refuse to answer also produce risky. Reporting those as valid would inflate our accuracy figure and hand you the bounces.
What file formats do you support?
CSV files with an email column, a phone column or both, up to 100,000 rows. The columns are detected automatically, and results download as separate files for valid, risky and invalid so you can send to each differently.
Can you validate phone numbers too?
Yes. Every plan checks each number's format, country and number type and converts it to international E.164 format, with no limit. Pro + Phone, at $49.99 a month, adds 5,000 live carrier lookups a month, which name the carrier and tell mobile from landline or VoIP, including for US numbers. Neither check can confirm that a number is currently in service.
What else is included besides verification?
On Pro, the email finder, which turns a name and company domain into a verified address; website enrichment for emails, owner names and socials; and SPF, DKIM, DMARC and blocklist checks are included with no per-use charge. The API includes 10,000 calls a month, then $1.50 per 1,000. Lead search is included with a published fair-use limit of 10,000 records a month, because it is the one feature with a real per-record cost.
Can I cancel my subscription anytime?
Yes. There are no contracts and no cancellation fees. Cancel from your account and the subscription ends at the close of the current billing period.
Can I get a refund?
No. Fees are non-refundable once charged, except where the law requires otherwise. That is why your first 100 checks are free with no card: you see real results before you pay. Cancel anytime from Billing to stop future charges.
Do you store my email lists?
Uploaded files are processed and the results made available for download; we do not keep your lists as a marketing asset or share them. Confirmed verification results are cached by address for 14 days so repeat checks are instant and consume no new connections.
