How MailboxValidator meters usage
In MailboxValidator’s own framing: bulk plans and api plans, each with 30-day validity. MailboxValidator's purchased credits carry a limited validity, so unused credits do not wait for you.
What to watch: every plan, including one-time bulk plans, is listed with 30-day validity, so queries you bought and did not use do not wait for you.
What it does well: MailboxValidator is worth keeping if you want separate bulk and API plans, so a one-off list clean does not touch the quota your sign-up form relies on.
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, MailboxValidator’s published route is $199.95 against $29.99 for Pro, a difference of $2,039.52 over a year.
For small volumes MailboxValidator costs less than we do. Up to 3,000 addresses can be bought from MailboxValidator for under $29.99, so if that covers your list and you verify it once, MailboxValidator is the better buy and a subscription to us is not.
