Rated 4 out of 5 stars

Although I only used the email verification - it's awesome, because this is so necessary for all address books on this planet! Sure it's not 100%, but I randomly cross-checked it and had great results! On big drawback with this great tool is though that you can't sort for columns when using the bulk email verifier - would be great if you could add that functionality! That way it's easier to double check the invalid emails or just remove the checkmark on delete when it's just a greylisting or a valid address! Thanks!

This review is for a previous version of the add-on (2.9.2). 

Click my name on the addon's page to get at my email address. I wonder if it isn't enough simply to sort the results prior to presentation rather than having the user trigger this interactively. Would like your opinion and to beta test the results. Thanks
