Easy user interface with many options available such as filtering out emails from junk folders or using regular expressions/regular expression search option when extracting data is extremely useful! It's free software so there are no costs involved but I would love if they had an API that allowed other developers access to their source code which could potentially make development easier at some stage too :) Have been able extract all required fields like names addresses etc without any issues though sometimes certain characters might get through into my results list - not sure why? But you have filters built-in so hopefully thats what its doing anyway :). Great tool overall especially once we've got everything working correctly within our system & ready to go live via Zapier integration!
