Proofy alternatives
If you are shopping away from Proofy, it is unlikely to be about candour or price, because they are strong on both. The gap is elsewhere.

Read from each vendor's own pricing page in September 2026. Vendors who block automated checks are shown without figures rather than with numbers we could not confirm. We are one of the options listed, and you should read this knowing that.
Why people look elsewhere
Not price, and that is worth stating plainly: at a hundred thousand addresses they are $89 and we are $139. If the deciding factor is the per-address rate, this comparison does not go our way.
$5 for a thousand, $18 for ten thousand, $89 for a hundred thousand, with a 15% discount on the monthly subscription version of the same tiers. New users get 5,000 checks for $5 as a one-off, which is the best value entry in this category. Credits never expire and survive cancellation.
What Proofy does that we do not
Migrating a verification workflow costs real time, so these are the capabilities to weigh against it.
- They never charge for unknowns or duplicates, printed on their own pricing page rather than buried in terms. That is the rule this category should have adopted years ago.
- Their accuracy wording hedges itself: designed for up to 99% on conclusive Valid and Invalid results, with catch-all and restricted servers named as returning Risky or Unknown. A vendor writing the denominator into its own claim is rare enough to credit.
- Credits survive cancellation and remain available indefinitely, which goes further than never expiring.
- At a hundred thousand addresses they list $89 against our $139. They are cheaper and we are not going to hide the row.
Before you move off Proofy
Run the same sample through two vendors and the interesting number is not how many came back valid.
Hold the replacement to the unknowns rule
Proofy prints it: no charge for unknowns or duplicates. Ask every alternative the same question in writing and treat a vague answer as a no.
Compare against $89, not against incumbent pricing
That is their published rate at a hundred thousand addresses. Most of the expensive end of this market is three to five times it.
Check what happens to credits on cancellation
Theirs remain available indefinitely. Several vendors expire credits at period end and a few expire them in thirty days.
Read their accuracy sentence in full
It names catch-all and restricted servers as the cases returning Risky or Unknown. Use that sentence as the standard when you read anyone else's claim.
What switching actually involves
Simple. The one thing to carry across is the expectation about unknowns, because Proofy sets a good one. Any vendor you move to should refuse to bill non-answers in writing, and most of this category still will not.
What no alternative to Proofy fixes
Questions about moving off Proofy
Is there an honesty reason to leave Proofy?
No. They hedge their accuracy claim, refuse to charge for unknowns and duplicates, and keep credits alive after cancellation. Inventing a complaint would make this page worse.
What is the entry actually like?
Five dollars for five thousand checks as a new user, then standard tiers afterwards. That trial is the best value entry point in this category and it is a paid one, so there is no free allowance to fall back on.
Why do people leave Proofy?
Not price, and that is worth stating plainly: at a hundred thousand addresses they are $89 and we are $139. If the deciding factor is the per-address rate, this comparison does not go our way.
How hard is it to switch verifiers?
For bulk cleaning, no harder than uploading the file somewhere else. For real-time checks on a signup form it is an API swap, which is an afternoon.
Proofy is one of the more honest vendors in this category. If you leave, do it for a specific reason and not because a comparison page implied one.
