Bulk Email Validator Free
Clean your email list before sending campaigns. Paste or upload emails to detect invalid, duplicate, disposable, role-based, risky, and bounce-prone addresses for free.
Private by design
Your file is read inside your own browser. Only the email addresses are sent for validation, and they are not stored after the check completes. We never send emails to your contacts, never use your list for marketing, and never sell it.

What Our Free Bulk Email Verifier Checks
Every address runs through multiple validation layers so you know exactly which contacts to keep, remove, or review before sending.
Email syntax validation
Checks whether each address follows a valid email format, catching missing @ symbols, broken domains, spaces, and invalid characters before they enter your campaign tool.
Domain check
Checks whether the email domain exists and appears usable, helping detect typos, expired domains, and addresses connected to domains that cannot receive mail.
DNS and MX record check
Looks up real mail exchange records to understand whether a domain is configured to receive email. A domain without working mail records is far more likely to bounce.
SMTP verification
Uses server-side verification signals to estimate whether an address can receive mail, without sending an actual message to the recipient.
Disposable email detection
Flags temporary and disposable email domains often used for one-time signups, fake leads, and low-quality contact lists.
Role-based email detection
Detects shared addresses such as info@, sales@, support@, admin@, and noreply@. These can be valid but often perform worse for outreach and personalized campaigns.
Duplicate removal
Finds repeated email addresses in your list so you can avoid sending multiple messages to the same contact and keep your data clean.
Bounce risk labels
Labels likely hard and soft bounces where signals are available, helping you understand which addresses to remove, review, or retry later.
Email score
Assigns a score to each address based on validation checks, risk signals, and deliverability indicators, so prioritising is simple.
CSV export
Export all results, valid emails, invalid emails, risky emails, or a cleaned list, ready for your next campaign.

Validation vs Verification, Bounces Explained
A quick, plain-language guide to the terms behind list cleaning.
Bulk validation vs verification
People often use these terms interchangeably. Email validation usually checks whether an address is properly formatted and connected to a real domain. Email verification goes deeper by checking mail server and mailbox-level signals where possible. This tool combines both approaches to help you clean email lists before sending. This free bulk email verifier also works as a bulk email checker free, email list validation free, and bulk email validation tool for cleaning campaign lists. You can use this bulk email validator free online without installing software.
Hard bounce vs soft bounce
A hard bounce is a permanent delivery failure. It usually means the address does not exist, the domain cannot receive mail, or the mailbox is permanently unavailable, and these should normally be removed. A soft bounce is usually temporary, caused by a full inbox, a server issue, greylisting, or rate limiting, and should be monitored and retried cautiously.
Email validation can help reduce invalid-address bounces, but it does not guarantee inbox placement or compliance with sender requirements.
Clean Your List Before You Send
Sending to invalid or risky addresses can increase bounce rates and damage sender reputation. List cleaning is one important part of deliverability, but not the only one.
For the strongest results you should also send only to people who expect your emails, authenticate your sending domain with SPF, DKIM, and DMARC, include a clear unsubscribe option, and monitor spam complaints. Google recommends keeping spam rates below 0.1% and avoiding 0.3% or higher. Yahoo also requires senders to keep spam complaint rates below 0.3%. Email validation helps reduce invalid-address bounces, but it does not guarantee inbox placement.
