First, look for a trustworthy company. Email marketing has grown in the past few years, and so has the number of email verifiers on the market. As a beginner, you may be tempted to go with the first platform you find online, but a bit of research pays off.


A well-equipped email verifier – not the ones you find online for free – should be able to offer you a suite of features to make a real difference in your email deliverability.


Not all email verifiers promise a certain accuracy rate. It’s certainly a question we advise you to ask before you make any purchase.

Money-back Guarantee

Another important aspect is to make sure your email verifier is going to provide you with a refund in case the results don’t meet your expectations.

Data protection

The General Data Protection Regulation (GDPR) has brought dramatic changes in the way businesses handle consumers’ private information. When choosing an email verifier, read their privacy policy carefully, make sure they’re GDPR compliant, and learn as much as you can about how they manage your data.

24/7 Customer Support

Let’s say you’ve made your choice and you’re getting ready to start cleaning your email list. But the platform you’re using is complicated and you just can’t figure out how the system works. In this situation, you'll need for sure customer support.
