Good tool for email id validation

What do you like best? Its a decent tool to validate email ids thought with some glitches. What do you dislike? Nothing much to dislike. However, the results were very similar to some free versions available. Would have expected more. What problems are you solving with the product? What benefits have you realized? We used it to check validity of email addresses to decrease chances of high bounce rates.

Decent but I find it bit expensive

What do you like best? Email validators have one job to do and I think mailboxvalidator does it really well. I never had any complaint about the quality. What do you dislike? I find it a bit expensive. They should re-evaluate their pricing. What problems are you solving with the product? What benefits have you realized? While running an email marketing campaign we often need to check the overall quality of the emails to increase the deliverability.
