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.
How SimpleVerifier’s flat plans compare
SimpleVerifier sells two plans, neither metered on email verification. Pro, $29.99 a month: Unlimited email verification, finder and phone format checks. Email + Phone, $49.99 a month: Everything in Pro, plus live carrier lookups for your phone lists. Re-verifying a list adds nothing to the bill, and confirmed results are cached for 14 days.
At 100,000 emails a month, Mailboxlayer’s published route is $249.99 against $29.99 for Pro, a difference of $2,640.00 over a year.
For small volumes Mailboxlayer costs less than we do. Up to 5,000 addresses can be bought from Mailboxlayer for under $29.99, so if that covers your list and you verify it once, Mailboxlayer is the better buy and a subscription to us is not.
