It really works! Unlike other mail merging add-ons, it doesn't limit its users with specific functionalities with paid ad unpaid plans... Gives a lot cool stuffs to surf and experiment with it. Thank you GMass for giving a wonderful experience to experimental users

Being able to create an e-mail list from already filtered e-mails (GMail can not do this on its own), with one click, saved me hours.
