Why use this email verifier?

Invalid emails kill your deliverability. Every bounce hurts your sender reputation, and too many bounces can get you blacklisted. Our free email verifier tool checks if an email address is real before you hit send.

Whether you're cleaning a prospect list, verifying a lead form submission, or checking individual emails before outreach, this tool gives you instant validation without the expensive monthly subscriptions.

Email validation isn't optional anymore. Email service providers track your bounce rate religiously. Exceed 2% bounces and you're flagged. Exceed 5% and your emails start hitting spam folders. At 10%, you're done — blacklisted across major providers.

The fix is simple: verify before you send. Our email verifier checks syntax, domain existence, MX records, and mailbox validity in seconds. We also flag disposable email services (those temporary inboxes people use to avoid your follow-ups) and role-based addresses like info@ or support@ that rarely convert.

Frequently asked questions

Everything you need to know about the email verifier

How does the email verifier work?

We perform multiple checks: syntax validation, domain existence, MX record lookup, and mailbox verification. We also check against known disposable email providers and identify role-based addresses.

Is this email verifier free?

Yes! You get 3 free verifications with no signup. Enter your email to unlock 10 more. No credit card required.

What does the email score mean?

The score (0-100) represents overall email quality. 80+ is excellent and safe to send. 50-80 is acceptable but verify manually for important sends. Below 50, avoid sending.

What is a disposable email?

Disposable emails are temporary addresses from services like Guerrilla Mail, 10MinuteMail, or Mailinator. People use them to avoid follow-ups. We flag these so you don't waste outreach on them.

What is a role-based email?

Role-based emails like info@, support@, sales@, or admin@ go to groups or shared inboxes, not individuals. They typically have lower engagement rates for sales outreach.

Why does "mailbox exists" sometimes fail?

Some email servers are configured to not reveal whether a specific mailbox exists (catch-all domains). In these cases, we mark mailbox existence as uncertain.

How accurate is the email verifier?

We achieve 95%+ accuracy for most business domains. Catch-all domains and some enterprise email systems may return uncertain results.

Do you store the emails I verify?

No. All verification happens in real-time and we don't store the email addresses you check. Your data stays private.

Can I verify emails in bulk?

This tool is designed for single email verification. For bulk list cleaning, check out dedicated email validation services.

Why is sender reputation important?

Your sender reputation determines if your emails reach the inbox or spam folder. High bounce rates damage reputation. Email providers track this across all major ESPs.

Should I verify before every cold email?

For purchased lists or scraped emails, always verify. For direct signups or business cards, verification is less critical but still recommended for important outreach.

What's the difference between syntax and domain checks?

Syntax checks if the email format is valid (has @, proper characters). Domain checks if the domain actually exists and can receive email (has MX records).
