CaptainVerify is one of the few email validation services that offers free deduplication. However, the website doesn’t list many other benefits, and there is no money-back guarantee or 24/7 customer support.

Let’s check out the table below to see exactly how ZeroBounce and CaptainVerify compare.

ZeroBounce charges $5 more to validate 10,000 email addresses. When you analyze the two services, you quickly understand why.

While CaptainVerify detects bounces, spam traps and disposable emails, the email verifier isn’t able to identify abuse emails and toxic domains. Also, it has no data appending features, as opposed to ZeroBounce.

Furthermore, the company does not state the accuracy it promises and the support page says you’ll get an answer “in less than 24 hours.”

With 24/7 customer support, ZeroBounce allows you to connect with a live person, via chat, in less than 15 seconds.

What’s more, apart from email verification, ZeroBounce offers an entire suite of email deliverability tools.

Check out the website – creating an account is free and comes with 100 email validations on the house!
