Why Are Google and Microsoft The Best Email? Security, security security! The most important thing about email is “security” because protecting your private and personal information is critical. Simply put, email is used for personal and business data, that if hacked, could be destructive to businesses and PC users. You hear a lot about hackers collecting data from major corporations worldwide, but not from Google or Microsoft. Hackers have been successful in hacking smaller leading Email providers such as Yahoo and AOL in the past. So, what sets Google and Microsoft apart from the rest? MONEY! Google and Microsoft can afford the best security. In addition, they can also afford to provide users an endless list of Free High-Quality products.
