Why You Need to Clean Your Email List?

A clean, up-to-date email list is essential for successful email marketing. Why? First, invalid and inactive emails drag down your open and click rates, damaging your campaign’s effectiveness. Second, spam complaints from bad addresses can hurt your sender reputation and delivery rates.

To boost your email marketing results, you need to verify and validate your list. That’s where a free email verification tool like ZeroBounce comes in. ZeroBounce checks each email in your list to confirm it’s deliverable and belongs to the intended recipient.

How Our Free Email Verifier Tool Works

To get started, just enter an email address in the field provided on our website. Our email verification API will then check that email against major mailbox providers like Gmail, Outlook, and Yahoo to confirm it’s valid and currently in use. If the email checks out, you’ll see a “valid” message. This means that your email is in working order and ready to receive your campaigns. Using only verified emails in your contact database helps maximize deliverability and open rates.

However, if an email bounces or is invalid, you’ll be notified right away. Our email checker provides details on the reason for the bounce, such as a full inbox, domain issues, or an inactive account. You can then promptly remove or re-confirm that email to keep your list clean. A clean, up-to-date contact list is essential for successful email marketing. Our free email verification tool makes it easy to validate new subscriber emails as well as double-check your existing database. Regularly verifying and maintaining your list helps build a strong foundation for high open and click-through rates, more sales, and happy customers.

Features of Our Email Validation Tool

Our free email verification tool offers several useful features to help you clean up your email list and boost your email marketing results.

Real-time Email Validation

As soon as you enter an email address into our email checker, it instantly verifies the email in real-time. It checks that the email structure is correct and that the domain is valid and currently active. This allows you to verify emails as you collect them or upload your list, instead of validating the entire list at once.

Catch-All and Role-Based Email Detection

Our email verifier tool can detect catch-all emails and role-based emails. Catch-all emails like ‘’ will accept any username before the @ symbol. Role-based emails contain generic roles like ‘info@’ or ‘admin@’ that could belong to multiple people. Detecting these kinds of non-personal emails allows you to remove them from your list or flag them for further verification.

Typo and Syntax Correction

Not all email addresses in your list may have been entered correctly. Our email validation solution uses algorithms to detect common typos, spelling mistakes, and syntax errors in email addresses and suggests corrections. This helps ensure emails that were simply entered incorrectly still get validated and added to your clean list.

Advanced Email Validation

For added security, enable our Advanced Email Verification. This uses a two-step process to verify that emails in your list are associated with real people. First, it validates the email structure and domain. Then it sends an email to the address with a verification link. Only once the recipient clicks the link is the email added to your validated list. This helps combat email spoofing and ensures all emails in your list represent real potential customers or subscribers.

ZeroBounce will automatically detect the format and start the verification process.

Check Email Status

Once your list has been uploaded, ZeroBounce will check each email for:

  • Valid syntax (is it formatted like an email?)
  • DNS lookup (does the domain exist?)
  • Mailbox verification (is this a real, active email?)

You’ll see the results displayed as valid (green), invalid (red), risky (yellow), or unknown (gray). Now you can confidently scrub invalid and risky emails from your list.

View Email Details

For any email, you can click “Details” to see specific information like:

  • The email provider (Gmail, Yahoo, etc.)
  • Location (country and region)
  • Date the email was first seen and last verified
