Gmail is the best-known email service provider in the world, but, lately, more and more people choose its alternatives. Reasons for this are various, but mostly include, privacy and security concerns, scarce additional features, and limited storage allowance.  Gmail's basic plan still comes for free, however, the service became infamous for scanning its users' mail, targeting them for ads, and even sharing their data with third parties. In the meantime, the Gmail interface doesn't offer much customization and it seems that its storage allowance keeps shrinking. All these factors are likely to make the users look another way when searching for a secure, efficient, and reliable email service.
