"Excellent email verification tool and best for catch all emails."

5/5

What do you like best about Mailall.io?

MailAll.io is outstanding. With over 12 years of experience in the data industry, I have consistently faced challenges with email verification for clients. It was a huge relief when we started using MailAll. Not only did it improve our verification ratio, but it also eliminated hidden bad catch-all emails. As a result, our email deliverability rate has now reached 98%. I highly recommend it! Review collected by and hosted on G2.com.

What do you dislike about Mailall.io?

Since it employs a two-layer email verification process, even a small file takes more than an hour to verify. However, that's acceptable, as quality comes at a cost. Review collected by and hosted on G2.com.

"The most accurate and thorough email verification tool I've used"

5/5

What do you like best about Mailall.io?

Other tools I have used do not indicate clearly if emails are valid or not. There is always a grey area with many of the addresses. Mailall makes it simple to know if emails are valid or not, with no ambiguity. I use the technology very heavily, which is an integral part of our company's email workflow.

What do you dislike about Mailall.io?

The website is very simple to use. Perhaps over time, they will add more features, but I found nothing to dislike right now. Review collected by and hosted on G2.com.

"Perfect for total list verification!"

5/5

What do you like best about Mailall.io?

It easily validates my entire list in a way I trust versus only giving me a little more than half back with a confident outcomes. This is exactly what I want from data validation - answers, not more questions. Review collected by and hosted on G2.com.

What do you dislike about Mailall.io?

Nothing so far; they made a great UI update that I enjoy using. I am looking forward to even more integrations coming out so I can plug it into all my tools. Review collected by and hosted on G2.com.
