Yahoo Mail ZeroMailI have been using yahoo mail for quite some time. However, I am not really impressed with their product or their improvements. Since 2013 I had issues regarding hacking, their advertisement placement is very frustrating, their platform is very slow and these factors are some to name a few. An alternative email platform that I would recommend and I am currently using is Milfence which offers an secure email service offering end to end encryption and a protected platform.
