The best thing about hirni as far I am concerned are its various features that makes it stand out from other clients available in market today like outlook or gmail etc., such feature includes ability to check multiple mail accounts at once with one click which saves me time when working online via PC/Laptop & mobile devices while traveling abroad (especially if you use more than 1 device). Other important points include:-1) Ability of viewing all emails received over past few days2.) Easy accessability3.). User friendly interface4.), Best security system5), Fastest speed possible6); Good customer support7,) Multiple ways user can logout so they don't have worry8)."Best" means something very different depending upon who's using this platform hence my own opinion might not be shared by everyone else but what i've said above holds true only within our team environment where we're actively utilizing these tools daily.-Ability To Check All Emails Received Within Past Few Days-Easy Accessibility -User Friendly Interface The best thing about hiri is that it has a lot of features which are very useful for me as I am using it to manage my emails. It also has a wide range of filters and search options which help me in finding relevant information from my inbox quickly and easily. Sometimes it can be slow while loading but not much to worry about. Overall it is a good app and I recommend everyone to use it. I am solving all my problems by using this software.
