Six questions, asked of the real mail server.
Verifyre does not guess from a database. For every address it resolves the domain, finds the mail exchangers and opens a real SMTP conversation, stopping before anything is sent.
Syntax
RFC 5321 rules, typo detection and provider-aware normalisation (dots and plus tags on Gmail).
Domain & MX
Does the domain resolve, and which servers accept its mail? SPF and DMARC are read too.
Reputation
10,000+ disposable providers, free mailbox providers and role accounts (info@, sales@) flagged.
SMTP handshake
EHLO, MAIL FROM, RCPT TO. The server tells us whether the mailbox exists. Nothing is delivered.
Catch-all probe
A random name at the same domain is tried; if it is accepted, the domain hides its mailboxes.
Score & verdict
Every signal rolls into a 0 to 100 score and one of four verdicts you can act on.
Everything you need
One verifier for every way email reaches you.
Check one address at the counter, a million in a list, or every sign-up as it happens on your forms.
Real-time verification
A full handshake in about a second. Verify a single address from the dashboard, the API or the form widget.

Senders who stopped guessing.
“Our bounce rate went from 9% to under 1% after one clean. Mailchimp stopped warning us and open rates climbed the same week.”
“We clean every client list through the Mailchimp integration before a campaign. The tag-back feature saves us an afternoon per client.”
“The API is straightforward and the catch-all scoring is honest. It tells us what it cannot know instead of pretending.”
“Watching the SMTP conversation on the homepage sold me. It is the only verifier that shows its work.”
“Our 400k event list took under an hour, duplicates removed for free, and the risky segment was exactly the people who never opened anyway.”
“Dropped the form widget on a client's WooCommerce store and fake sign-ups fell off a cliff. Two lines of code.”
