Verifying an email address before sending a campaign is one of the easiest ways to protect your sender reputation and improve deliverability. With Proofy free email checker, you can instantly test any email address and find out whether it’s valid, risky, or disposable - no registration required.
The process is simple: enter an email into the checker, click Validate, and in a few seconds you’ll see accurate results powered by Proofy real-time checking tool. Our smart verification engine analyzes multiple signals to confirm whether an address is valid and active - safely, instantly, and without sending any emails.
Why does this matter? Sending emails to outdated or fake, disposable addresses increases your bounce rate and can damage your domain’s reputation. By verifying each address in advance, you ensure that your messages reach real inboxes, improve open rates, and maintain a clean mailing list that supports your marketing ROI.
For teams managing large databases, Proofy also provides bulk verification, API access, and widget integration - so you can scale from a single free check to a full enterprise-grade solution.

It’s fast, accurate, and completely free for single email checks.
Proofy Free Email Checker connects to mail servers in real time to check if an address is valid and deliverable — without sending a message. It detects typos, inactive domains, and fake or temporary emails. You just enter an email, click Validate button, and instantly get results showing if it’s safe to use or not.
Proofy Free Email Checker delivers 99%+ accuracy on valid and invalid results. It checks email syntax, confirms MX records and domain health, then performs an SMTP handshake - all without sending an actual message. Catch-all domains are the only exception where results may be uncertain.
Yes. Proofy Free Email Checker works with all major email providers including Gmail, Yahoo, Outlook, iCloud, and corporate domains. It connects directly to each provider's mail server to confirm whether the specific mailbox exists and can receive messages.
After running a free check, you’ll see one of the following statuses:
Valid — the email address exists and can receive messages.
Invalid — the address doesn’t exist or will bounce.
Risky — catch-all or role-based email, might deliver inconsistently.
Disposable — a temporary address used for one-time registrations.
These results help you keep only real and safe emails in your list.
If you want to check multiple addresses at once, you can use Proofy Bulk Email Verification Service or Email Validation API. They work with the same accuracy as the Free Email Checker but allow you to verify entire lists automatically. You can upload a CSV file, integrate with your app, or connect Proofy API for real-time validation at scale.
Yes, it's completely safe. Proofy does not store, share, or log the email addresses you check using the free tool. Your data stays private. The verification process is performed in real time and no information is retained after the check is complete.
A disposable email is a temporary address created for one-time use, often through services like Guerrilla Mail or Temp Mail. These addresses expire quickly and are commonly used to bypass sign-up forms. Proofy detects disposable emails automatically and flags them separately so you can remove them from your list.
