How it works

Three steps, under a second

01

Paste the address

Enter any email address you want to check: a prospect, a lead or your own.

02

Multi-layer check

Syntax, domain, MX, live SMTP mailbox ping and catch-all detection run in real time.

03

Get the verdict

See whether it’s deliverable, invalid or risky, before it ever bounces.

Why it matters

Bounces quietly wreck deliverability

A handful of hard bounces is all it takes for mailbox providers to flag your domain. From there, opens fall and your outreach lands in spam. Verifying before you send is the cheapest reputation insurance there is, and it’s built into every PipeLime send.

  • Keep bounce rates under the 2% danger line
  • Protect your domain reputation and sender score
  • Stay off Spamhaus and provider blocklists

FAQ

Email verifier questions

Is this email verifier free?
Yes. You can verify a couple of email addresses per day for free with no signup. Create a free account to verify more, check lists in bulk and wire verification into your outreach.
How does the email verifier work?
It runs the same in-house checks PipeLime uses before every send: syntax and formatting, domain and MX records, a live SMTP mailbox ping, plus catch-all, role and disposable-address detection, all in real time.
What does “catch-all” mean?
A catch-all (accept-all) domain accepts mail for any address, so a mailbox can’t be individually confirmed. We keep that verdict honest instead of forcing it to “valid”, so you know it carries more risk.
Do you send a test email to the address?
No. The SMTP mailbox ping is a lightweight protocol handshake that checks whether the mailbox exists without ever delivering a message, so the person you check never sees anything.
How accurate is it?
By combining a live SMTP ping with domain and MX validation rather than a stale database, the engine reaches roughly 99% accuracy on deliverable mailboxes and keeps real-world bounce rates under 2%.
