Mail is a message which may contain text, audio, image, or video. We can send mail using the internet to anyone. For sending mail, we have to provide the receiver's email address using which the mail gets delivered. We can send one mail to multiple receivers at one time.
Organizations that contain sensitive information always need data security. While communicating using emails, this organization required privacy. Gmail provides you with a secure email communication facility. The mail you sent using Gmail is encrypted or unable to read when it reaches the destination. Then it gets readable. Where servers are located by mail, the rules and regulations get strict. Proton mail is located in Switzerland, where the privacy rules are stringent. There is no fixed parameter for the secure mail approach; every approach is changed according to the provider. Every provider changes its facility as per the price calculations. Budget is one of the most significant factors which everyone has to consider because not everyone gives free services like google or outlook.
