Best for cheap email list checks by the credit
Proofy verifies email lists with credits that never expire and does not charge for unknowns, starting at $5 for 5,000. Only that $5 trial pack has a price on the page, there is no free plan, and risky and unknown results still come back for catch-all servers.
Who Proofy is for
- Fits if you have one list to clean and want to pay about $5
- Works for developers who want an API and a sign-up widget
Who Proofy is not for
- Tight if you want to try it free, as only a single-address checker is free
- Watch out: larger packs and subscriptions showed no prices when the page was read
- Watch out: the vendor says verification does not guarantee delivery
- Watch out: there is no desktop or mobile app

Keep Proofy, or make your own?
Keep it
Nothing Proofy does is plain enough to make in a weekend. The 5 things listed below take a company.
It costs $5, paid once.
What you could not
- Checking that an address exists without writing to it.
- An API that other software can build on.
- Hooks into the device itself: widgets.
- What a company asks for before it lets staff use something: roles and permissions.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Proofy’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Proofy?
Proofy verifies email addresses without sending a message, labeling each as valid, invalid, risky or unknown and flagging disposable, catch-all and role-based ones. Lists go in as CSV or TXT files, and a REST API, bulk and batch endpoints, a JavaScript widget and webhooks cover automated use. Credits do not expire and duplicate or unknown results are not charged.
Worth knowing
- The only price shown on the pricing page is the $5 trial pack; larger packages and subscriptions are set with a volume selector that showed no prices when read.
- Catch-all and restricted mail servers can come back Risky or Unknown, and the vendor says verification does not guarantee delivery.
- Web dashboard and API only; there is no desktop or mobile app.
Key features
- Bulk verification
- Upload a .txt or .csv file up to 65 MB; result columns are added to the original file and the data layout is kept.
- API, widget and webhooks
- Single, bulk and batch API endpoints plus a JavaScript widget and webhook support, documented at docs.proofy.io.
- Risk and type detection
- Flags disposable, catch-all, role-based and mailbox-full addresses and shows the mail provider behind each one.
- Free single checker
- A free checker takes one address at a time with no file upload.
- Credit rules
