Mailsurity vs Clearout
Clearout covers email and phone verification plus a lead-finder tool, with a free disposable-email checker offered on the side. Mailsurity narrows to one question: is this signup email disposable or temporary, answered in real time with an AI fallback for domains a static list hasn't seen yet.

Which one should you use?
Pick Clearout if…
You need general email and phone verification, or lead-finding, with credits that never expire, and a free disposable-checker tool covers the rest of what you need there.

You're stopping disposable/burner signups at the moment they happen, and want a real-time endpoint with an AI fallback for brand-new domains and per-team allow/deny rules, not a general-purpose verification bundle.
FAQ
Is Clearout’s free disposable-email checker enough, or do I need Mailsurity too?
Clearout runs a free, standalone Disposable Email Checker, useful for a quick manual lookup. It isn’t wired into Clearout’s paid verification plans as a named feature, and the detection method isn’t published. Mailsurity’s free tier (500 credits, no card) runs the same AI-assisted cascade paid customers use, including an AI fallback for brand-new domains, which makes it a closer fit for checking real signups in production rather than one-off lookups.
How does Clearout’s pricing compare to Mailsurity’s?
Clearout’s pay-as-you-go pricing starts around $21 for 3,000 credits, or a monthly subscription from about $31/mo for 5,000 credits, with credits that never expire. Those credits cover Clearout’s broader email/phone verification, not disposable detection specifically. Mailsurity’s plans are priced for disposable-email detection alone; see the current figures below.
Does Clearout specialize in disposable-email detection?
No, Clearout is built around general email and phone verification, plus a lead-finder tool, with disposable checking offered as a free add-on tool rather than the core product. Mailsurity is the reverse: disposable/temporary detection is the only thing it does, with an AI fallback and per-team rules built for that use case.
