Email verification subscription

Monthly cost at three volumes

Lowest published route for that many verifications every month, read from each vendor's pricing page. Subscriptions are priced at the first tier whose allowance covers the volume; pay-as-you-go is priced as buying the covering pack each month. Vendor prices read 12 Oct 2026 to 5 Nov 2026.

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 October 31, 2026.

Monthly or yearly

Pro is $39 billed monthly, or $390 billed yearly, which is ten months' price for twelve. Live carrier lookups are a $20 a month add-on (Pro + Phone is $49.99). Business ($99) and Agency ($249) raise the full-speed volume to 300,000 and 750,000 a month. All cancel from your account.

What to compare between subscriptions

The headline price is the least useful number. Compare the allowance at your actual volume, whether unused credits roll over or reset, whether finding and verifying draw on the same pool, and what a second pass over the same list costs.

Our every vendor we price pages record each of those from the vendor's own pricing page, with the date it was read.

Common questions

How much is an email verification subscription?

SimpleVerifier Pro is $39 a month or $390 a year, never cut off: the first 100,000 emails a month run at full speed, then big lists run slower. Credit-tier subscriptions from other vendors are priced by monthly allowance; this page compares them at 10,000, 50,000 and 100,000 a month.

Do unused verifications roll over?

There is nothing to roll over on Pro: it never cuts you off, and its 100,000 full-speed emails reset each month. The Starter allowance resets and does not roll over. On credit-tier plans from other vendors it varies; some roll over, some reset each month.

Is a subscription better than pay as you go?

For one small list a year, pay as you go is usually cheaper. For lists you verify every month, or re-check before each send, a subscription usually is.
