Build a Better Email List With ZeroBounce’s Free Email Validity Checker

Verify up to 100 emails per month, free.

Nearly 16 percent of emails go missing or get caught by spam filters. Before an email can be opened, it has to be received.

If you haven’t conducted an email validity check, you could be reaching out to email addresses that are fake or no longer working. That means you’re talking to an audience filled with empty chairs.

Make sure your message is delivered and received by real people.

Try It Free

ZeroBounce offers free, fast and accurate email validation.

Verify emails online using our free email validity checker. This allows you to:

Check new emails as you go.

Maybe someone submitted a contact form on your site and you want to ensure the email address isn’t spam. Or you’ve identified a prospect on LinkedIn and want to ensure their email address is current before reaching out. Use our free email address verifier to check emails as you go — and keep your list clean from the start.

Test email validity for up to 100 emails monthly.

Already have an email list? Upload a batch of up to 100 contacts and we’ll verify them for you. We’ll also go a step further and tell you if it’s toxic (a bot-created, spam or abuse email address) or disposable (temporary email that will eventually expire and bounce). When available, we’ll also share the name, gender and location of the email holder, which is key for creating personalized email content. Roughly 80% of customers are more likely to make a purchase when brands personalize an experience, according to Epsilon research.

The benefits of conducting a free email check include:

Improved bounce rate:

Weed out invalid emails from your list with our bulk email validity system. It also removes temporary email addresses, which will eventually bounce. The lower your bounce rate, the more effective your emails will become at reaching real people and converting them to customers.

Fewer spam complaints:

Separate out abuse emails from your database. Abuse email addresses belong to people who are known to flag messages as “spam,” which can negatively impact your inbox placement. By removing people who often mark messages as spam from your list, you ensure your marketing messages only reach people who want to hear from you — and are more likely to become customers.

Stronger sender reputation:

Your sender reputation is like the credit score for your email address. The more invalid, spam or abuse email addresses you contact via email, the worse your emails perform and the lower your score. By removing bounces, spam traps and other risky emails, ZeroBounce improves your reputation and helps you stay in good standing.

Better engagement:

You want people to see, open and act when they receive your marketing emails. Before that engagement can occur, the email has to be delivered. Use our email verifier for a free email check, which improves deliverability. Creating a clean list of working emails also increases open rates, click-through rates and — most importantly — conversions.
