The best thing about this is that it's free of cost! I don't think there exists anything like its benefits in any other service provider out here - especially for business owners who want their organization email communication under some sort safety from all types or threats mentioned above (spamming etc.). It just needs more features being added which will definitely make our life easier as an admin person at my office!! Nothing specific can be said abour janumail yet but once we get enough requests by users then surely they'll add those things so people would feel satisfied with them instead having doubts over quality stuffs provided through such services only.
