Clean your email list database with our free email checker and verifier

Some of these emails may indeed be spam — and the email recipient marks it as such.

Other times, hard-working marketers like yourself might have purchased an email list that — unknowing to them — contained spam traps (fake emails used to catch spammers).

Many email lists available for purchase are compiled by taking email addresses found on the web. That means a real person never opted in to hear from you.

Internet service providers and blacklist providers seek to prevent spammers from committing fraud. They put fake email addresses in publicly accessible digital spaces (like blogs and forums) to catch and block spammers.

Unfortunately, if you purchased a list with a spam trap, your emails could eventually get routed directly to spam or blocked entirely.

Other times, your email list may simply be outdated. People get married and change their last names in their email addresses. Or they switch jobs, and their email address becomes invalid.

Emails to fake email addresses lead to one thing - a bounce.

More bounces will hurt your sender reputation and ultimately destroy your email deliverability. Our email checker allows you to spot fake addresses so that you can remove them from your email list.

Fake addresses can pop up for a variety of reasons.

Some can be simple input errors that lead to misspellings or incorrect email syntax. Users might also intentionally enter a fraud email address to protect their privacy but still get access to your content.

Disposable email addresses also pose a problem as they are valid at the time of entry on your sign-up forms. It’s enough to get by an email checker API, but it quickly self-destructs and becomes invalid. Thus, the cycle of bouncing messages quickly resumes, and your sender score continues to suffer.

You can’t afford to have your emails sent to spam or blocked, jeopardizing your sender reputation. Whether you stick with this free email verifier tool or make the most of our system by checking your entire email list in bulk, a working list of current contacts is critical to the success of your marketing efforts.

Some of the benefits of cleaning up your list include:

At ZeroBounce, we serve more than 200,000 customers, made up of brands and businesses of all sizes. Like you, they rely on email to engage with prospects and customers. Valid email addresses are essential to getting your message to the right place.

Our free email verifier tool will never cost you anything. Feel free to enter as many of your contacts’ email addresses as needed to find out which are valid or invalid.

If you want to check emails in bulk, fill in social data, discover Activity Data, score your most active contacts, or use our real-time API, you’ll need ZeroBounce credits. Every email address you need to check consumes one credit, and your purchased credits will never expire.

For anyone sending out email campaigns regularly, we recommend verifying your email contacts at least once a quarter (every 3-4 months). This helps you stay on top of any new leads you may obtain and identify previously valid addresses that are now unused or dormant.

If you use our email verification API, you may be able to extend your cleaning schedule to once every six months. A real-time email checker helps stop fake or fraudulent addresses like disposable emails at the gate so that they never enter your email database.

ZeroBounce offers superior email validation compared to services like NeverBounce, Snov.io and Hunter.io, with an industry-leading 99% accuracy. We know the importance of connecting with valid contacts, so we only deliver validation results you can trust.

We also enhance your email checker experience by offering valuable insights regarding the person’s email behaviors. You can add Activity Data to your validation reports and score those addresses on a scale from 1-10 to determine who’s most likely to engage with your next campaign.

Our email checker also offers insights into your catch-all email addresses. Those are company email addresses that initially served to catch misplaced emails but now often serve as a haven for spam. We score those catch-all addresses to find active ones, helping you determine which are worth messaging and which you should avoid.

Finally, ZeroBounce offers superior data protection, meaning that your email and customer data is always secure. We can never view your uploaded data and supply your results directly to you with an encrypted key. We also automatically delete your uploaded data after 30 days to eliminate unnecessary risk.

ZeroBounce is AICPA, SOC 2 Type 2 and ISO 27001 certified. We also comply with state, national and international compliances, including CCPA, GDPR, India DPDP and Privacy Shield, making us the most trustworthy email validation service available.
