Email Verification Flat Rate: One Monthly Price, No Credits
Flat-rate email verification means one monthly price instead of buying credits per address. SimpleVerifier Pro is $39 a month: the first 100,000 checks a month at full speed, then slower, never cut off. You can try 100 free checks first, with no card.
The attraction is predictability. You stop doing arithmetic every time you load a list. Here is how to judge a flat rate, and when it is the wrong choice.
Read the fine print
- The full-speed volume. A flat rate with no stated volume hides a limit somewhere. SimpleVerifier states it: 100,000 checks a month at full speed.
- What happens past it. Some plans stop. Pro keeps going in a slower lane.
- What is excluded. API calls and phone lookups are separate allowances on Pro. See pricing.
- Cancel terms. Look for a monthly plan you can end without a call.
Our unlimited email verification page explains the fair-use mechanics in detail.
Who benefits
Teams that load new lists every week: cold email senders, agencies, recruiters, and anyone cleaning a CRM on a schedule. They stop buying packs and stop worrying about credits that expire. See the subscription comparison for other monthly plans.
How SimpleVerifier fits
Sign in with Google at the verify page, run 100 free checks, no card, then move to Pro for $39 a month. Pro does real SMTP mailbox checks, labels catch-all and risky addresses, takes CSVs up to 100,000 rows and exports valid, risky and invalid separately. Agencies handling many client lists can look at the agencies page.

When another vendor is cheaper
Flat rate loses when you rarely verify. MillionVerifier's 100,000 pack at $149 never expires, so if you clean 100,000 addresses twice a year, you pay less than twelve months of Pro. A pack of 10,000 at $39 matches one month of Pro and does not recur. Flat rate wins as soon as you clean more than a few times a year. The MillionVerifier and Emailable pages show break-even points, and the pay as you go page covers the packs side.
Bottom line
Choose flat rate if you verify regularly and want a fixed bill. Choose a pack if you verify rarely. Read the fair-use line either way.
Common questions
What is flat-rate email verification?
A plan with a fixed monthly price instead of per-address credits, so a bigger list does not raise that month's bill.
Is SimpleVerifier really flat rate?
Pro is $39 a month. The first 100,000 checks a month run at full speed; past that, lists run slower but are never cut off. Email finder and API calls are separate allowances, with API calls past the included 10,000 billed per 1,000 on monthly billing.
When is a flat rate not worth it?
If you verify a list a few times a year, a prepaid pack costs less than twelve monthly payments.
Can I cancel?
Yes, Pro can be cancelled anytime.
Check your list before you send
Real mailbox checks over SMTP, and nothing is sent to the address. Sign in with Google and your first 100 email checks are free, no card. Plans for bigger lists are on the pricing page.
