- On these published prices SimpleVerifier costs less at every volume Abstract API's page prices (1,000, 10,000, 50,000, 100,000 a month), with a tie at 10,000.
- SimpleVerifier’s metered plan (Starter at $9 a month for 2,500 emails a month) resets every billing month, with no rollover, and cover email verification only, without the API, finder or phone lookups. Pro includes them.
- Pro is never cut off: the first 100,000 emails a month run at full speed, then lists of 2,000 rows or more run in a slower shared lane. Large lists queue rather than fail, with an ETA on the job card.
- “Not published” means Abstract API’s page did not price that volume; we do not extrapolate. Run your own numbers in the cost calculator.
Abstract API cost per 1,000 emails at 10k, 100k and 1M a month

|---|---|---|
| 10,000 | $3.90 | $3.90 |

How Abstract API meters usage
In Abstract API’s own framing: monthly request allowance. What to watch: the plan is a request quota, so a bulk clean and your live sign-up checks compete for the same allowance.
What it does well: Abstract API is worth keeping if you already use Abstract's other APIs, such as IP geolocation or phone validation, and want one key and one bill.
For small volumes Abstract API can cost less than Pro: up to 5,000 addresses can be bought from Abstract API for under $39. If that covers your list and you verify it once, Abstract API may be the better buy.
When to pick Abstract API instead
- Pick Abstract API if you already use Abstract's other APIs, such as IP geolocation or phone validation, and want one key and one bill.
How to work out what Abstract API will cost you
- 1
Count how many addresses you verify in a typical month, including re-checks of lists you already cleaned.
- 2
Find the smallest Abstract API tier whose allowance covers that number in the plans table, and compare it with buying a pay-as-you-go pack of that size, if Abstract API sells one.
- 3
Check whether unused Abstract API credits expire before you would use them, and whether the plan meters finding and verifying from the same pool.
- 4
Compare the result with SimpleVerifier: Starter at $9 a month for 2,500 emails a month, or Pro at $39 a month, never cut off: the first 100,000 emails a month run at full speed, then big lists run slower.
Before you buy Abstract API credits, test an address here
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.
