Free email verifier
Check whether an address can receive mail before you send to it. No account, no card, no limit worth mentioning.
Sending to addresses that bounce is the fastest way to lose your sender reputation. One bad list can take a domain months to recover from.
What gets checked
Syntax and domain
The address is parsed properly, and the domain is resolved to see whether it exists at all.
MX records
We look up the mail exchangers for the domain. No MX record means nothing can be delivered there, whatever the address looks like.
Disposable and role accounts
Throwaway inbox providers are flagged, as are addresses like info@ and sales@ that reach a rota rather than a person.
A score you can act on
Every result carries a 0-100 confidence score and says plainly what the check could and could not establish.
Questions
- Does this prove the mailbox exists?
- Not on its own. A DNS-level check confirms the domain is set up to receive mail; it does not open a connection to the mail server, so it cannot confirm one particular mailbox. Every result tells you which kind of check produced it rather than presenting both as the same thing.
- Why does a valid-looking address come back as risky?
- Usually a catch-all domain, which accepts mail for every address whether or not the mailbox exists. That makes a positive result meaningless there, and pretending otherwise would cost you deliverability rather than the address.
- Is it really free?
- Yes, and it stays free inside the product too. Verification is unlimited on every plan including the free one, because it costs a DNS lookup and gating it would be theatre.
- Do you store the address I check here?
- No. This page runs the check and returns the result. Nothing is written to an account, because there is no account attached to it.
Verification is the easy half
Prospexly finds the companies worth contacting, the people inside them, and sends the sequence from your own mailbox. Verification is built in and unlimited on every plan, including the free one.
