Unlimited email verification, and what the limit really is
SimpleVerifier Pro is $29.99 a month with no cap on email verifications: no credits, no allowance, nothing that expires. The real ceiling is throughput, which we publish: up to 45 addresses a minute per account and 100,000 rows per CSV. Larger lists queue rather than being refused or billed extra.
"Unlimited" is used loosely in this market, so it is worth saying exactly what it means here. There is no monthly number of verifications after which you pay more or get cut off. There is a speed limit, because mail servers throttle verifiers that probe too fast, and a fair-use clause in the terms for use that threatens the service for other customers.
What that changes is how you plan. A credit-based plan makes you size a tier and ration re-checks. A flat plan lets you verify a list, verify it again before the next send, and run sign-up checks through the API without watching a balance.

Each vendor's lowest published route for verifying that many addresses every month, read from its pricing page. Pay-as-you-go vendors are priced as buying the covering pack again each month. Where a vendor is below our figure, it costs less at that volume. Each vendor links to its comparison page, which records the date its prices were read. Check their site for current pricing before you buy.
When unlimited is the wrong choice
If you verify a few thousand addresses a month and never re-check, a small metered plan can cost less than $29.99, and several vendors in the table below are below us at 10,000 a month. Buy one of those, or our one-time packs, and do not pay for capacity you will not use.
The flat plan pays off when volume is large, uneven, or repeated: a 100,000-row CRM, weekly lead imports, or lists you re-check before every campaign.
What is included
Bulk CSV uploads, the email finder, website enrichment, phone format and line-type checks, the API with no per-call fees, the Google Sheets add-on and the Instantly and Smartlead campaign integrations. Lead search is the one part with a fair-use limit, of 10,000 records a month.
Common questions
- Is the email verification really unlimited?
- There is no monthly cap on email verifications on Pro. The limits are throughput (up to 45 addresses a minute per account), 100,000 rows per CSV, and a fair-use clause in the terms.
- How many emails can I verify in a month?
- At 45 a minute, an account can process tens of thousands of addresses a day. A 100,000-address list takes about 38 hours.
- Is unlimited verification more expensive than paying per email?
- At small volumes, often yes: a metered plan for a few thousand addresses can be under $29.99. At larger or repeated volumes the flat price is usually lower. The table on this page shows both cases.
- Can I cancel?
- Yes, at any time from your account, and there is a 7-day money-back guarantee.
