Gmail is a massive mailbox provider operated by Google. It currently stands as the largest email service in the world. It serves approximately 1.8 billion users across the globe.

People can access the service through webmail in a browser. It is also available via mobile apps on iOS and Android. Some users connect through third-party email clients using POP and IMAP protocols. These protocols allow different software to communicate with the Gmail servers.

The service manages how users receive and store digital information. When a message arrives, Google's servers automatically scan it. This process helps filter out spam and malware. Spam is unwanted or harmful email. Gmail uses a community-driven system for this protection. If a user marks a message as spam, the system learns from that action. This information helps the system identify similar messages for all other users.

Storage is a central part of the Gmail experience. Individual users receive 15 gigabytes of storage for free. This storage is shared among Gmail, Google Drive, and Google Photos.

Users can receive emails up to 50 megabytes in size. This limit includes any attachments. However, users can only send emails up to 25 megabytes in size. To send larger files, users can insert files directly from Google Drive. If a user needs more space, they can subscribe to Google One. This paid service offers personal plans up to 2 terabytes.

The Gmail interface has evolved significantly since its launch. The designer, Kevin Fox, created an interface focused on search and conversation threading. Conversation threading groups several messages between people onto a single page. This approach was later copied by many competitors. Instead of traditional folders, Gmail uses labels. Labels act like tags to organize messages flexibly. The interface also includes importance markers and filters. Filters can automatically organize, delete, or forward incoming emails.

In 2013, Google added tabs to categorize the inbox into Primary, Social, Promotions, Updates, and Forums.

Gmail has a long history of technical development. It launched as "Google Mail" in a beta version on April 1, 2004. At that time, it offered one gigabyte of storage. This was much higher than what competitors offered. On April 1, 2005, the storage limit doubled to two gigabytes. In October 2007, it increased to 4 gigabytes. By 2012, the limit rose to 10 gigabytes. The service finally moved out of its beta stage in 2009. Gmail was also notable for its early use of Ajax. Ajax is a technology that helps web pages update smoothly.

Modern Gmail includes many advanced security and smart features. Users can use two-factor authentication to secure their accounts.

This adds an extra layer of identity verification. The service also includes a Confidential mode. This allows senders to set expiration dates for sensitive messages. They can even revoke a message entirely. Google also provides "Smart Reply." This feature uses machine intelligence to scan messages. It offers three responses that a user can edit and send. In 2020, Google gave users more control over these smart features and personalization settings.

Accessibility is a major focus for the service. Gmail supports 72 different languages. This includes languages like Arabic, Chinese, Hindi, and Zulu. In 2012, Google added over 100 virtual keyboards and input methods. This helps users write in languages not limited by their physical keyboard. In 2013, handwriting input support was added. Gmail was also the first major provider to allow emails with accent marks. It also supports characters from outside the Latin alphabet. This makes the service a truly global tool for communication.
