Pricing Comparison Of Best MailboxValidator Alternatives

Before we explore each of these software and services in detail, allow me to briefly talk about MailboxValidator and why you should look for a better email verification solution.

What Is MailboxValidator?

MailboxValidator is an email validation and bulk email verification service. The company has been in business since 2013 and is headquartered in Malaysia.

Since its launch, the software claims to have cleaned over 1 billion email addresses. This is possible only because of the use of some robust email verification features. So you could clearly estimate that the software is widely used around the world. Not to forget, it proudly lists some of its notable clientele as well.

In addition to this, MailboxValidator is extremely developer-friendly. For starters, it offers direct integration with various email marketing services. Besides this, it also comes with APIs, extensions, and SDKs to connect with any third-party software.

That being said, despite such a good set of features and reputation, MailboxValidator fails to meet our expectations.

We have found some major drawbacks that you, its user have to face while using it…

Cons Of MailboxValidator – Reasons Why You Must Look For A Better Alternative

• Despite being in business for such a long time and utilizing some robust features, MailboxValidator only offers 96% email verification accuracy. At the same time, other MailbocValidator competitors offer up to 99% accuracy.
• You’d find that the software is a bit difficult to use at first. It is also notable to point out that the user interface seems a bit outdated as well.
• MailboxValidator is significantly more expensive than some of the other email verification services. Moreover, you’d find that it offers different pricing plans for bulk email verification and API.
• It was surprising to find out that your unused email verification credits will expire in 30 days, from that date of purchase. MailboxValidator is the only service that follows this absurd rule.
• We also found that (through G2 and Trustpilot) MailboxValidator support is painfully slow. You’d often get replies to your support queries in days.
