- On these published prices SimpleVerifier costs less at every volume Mailboxlayer's page prices (1,000, 10,000, 50,000, 100,000 a month).
- 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 Mailboxlayer’s page did not price that volume; we do not extrapolate. Run your own numbers in the cost calculator.
Mailboxlayer cost per 1,000 emails at 10k, 100k and 1M a month

|---|---|---|
| 10,000 | $7.50 | $3.90 |

How Mailboxlayer meters usage
In Mailboxlayer’s own framing: monthly api request quota. What to watch: it is an API quota, not a list tool, so cleaning a CSV means writing the batching yourself and every row counts against the month.
What it does well: Mailboxlayer is worth keeping if you only need a validation call inside your own code and are comfortable building the upload, de-duplication and export around it.
For small volumes Mailboxlayer can cost less than Pro: up to 5,000 addresses can be bought from Mailboxlayer for under $39. If that covers your list and you verify it once, Mailboxlayer may be the better buy.
When to pick Mailboxlayer instead
- Pick Mailboxlayer if you only need a validation call inside your own code and are comfortable building the upload, de-duplication and export around it.
How to work out what Mailboxlayer 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 Mailboxlayer 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 Mailboxlayer sells one.
- 3
Check whether unused Mailboxlayer 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 Mailboxlayer 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.
