Email service provided by Google

Gmail is the email service provided by Google. as of 2019, it had 1.5 billion active users worldwide, making it the largest email service in the world. Users in need of more storage can purchase Google One to increase this 15 GB limit. Users can receive emails up to 50 megabytes in size, including attachments, and can send emails up to 25 megabytes. Gmail supports integration with Google Drive, allowing for larger attachments. Gmail has a search oriented interface and supports a "conversation view" similar to an Internet forum. The service is notable among website developers for its early adoption of Ajax. Google's mail servers automatically scan emails for multiple purposes, including to filter spam and malware and, prior to June 2017, to add context sensitive advertisements next to emails. This advertising practice has been significantly criticized by privacy advocates with concerns over unlimited data retention, ease of monitoring by third parties, users of other email providers not having agreed to the policy upon sending emails to Gmail addresses, and the potential for Google to change its policies to further decrease privacy by combining information with other Google data usage. The company has been the subject of lawsuits concerning the issues. Google has stated that email users must "necessarily expect" their emails to be subject to automated processing and claims that the service refrains from displaying ads next to potentially sensitive messages, such as those mentioning race, religion, sexual orientation, health, or financial statements. In June 2017, Google announced the end of the use of contextual Gmail content for advertising purposes, relying instead on data gathered from the use of its other services. On April 1, 2005, the first anniversary of Gmail, the limit was doubled to two gigabytes of storage. Georges Harik, the product management director for Gmail, stated that Google would "keep giving people more space forever." In October 2007, Gmail increased storage to 4 gigabytes, after recent changes from competitors Yahoo and Microsoft. On April 24, 2012, Google announced the increase of storage included in Gmail from 7.5 to 10 gigabytes ("and counting") as part of the launch of Google Drive. On May 13, 2013, Google announced the overall merge of storage across Gmail, Google Drive, and Google+ Photos, allowing users 15 gigabytes of included storage among three services. On August 15, 2018, Google launched Google One, a service where users can pay for additional storage, shared among Gmail, Google Drive and Google Photos, through a monthly subscription plan. as of 2021, storage of up to 15 gigabytes is included, and paid plans are available for up to 2 terabytes for personal use. There are also storage limits to individual Gmail messages. Initially, one message, including all attachments, could not be larger than 25 megabytes. This was changed in March 2017 to allow receiving an email of up to 50 megabytes, while the limit for sending an email stayed at 25 megabytes. In order to send larger files, users can insert files from Google Drive into the message.

The Gmail user interface initially differed from other web mail systems with its focus on search and conversation threading of emails, grouping several messages between two or more people onto a single page, an approach that was later copied by its competitors. Gmail's user interface designer, Kevin Fox, intended users to feel as if they were always on one page and just changing things on that page, rather than having to navigate to other places. Gmail's interface also makes use of 'labels' (tags) – that replace the conventional folders and provide a more flexible method of organizing emails; filters for automatically organizing, deleting or forwarding incoming emails to other addresses; and importance markers for automatically marking messages as 'important'. In November 2011, Google began rolling out a redesign of its interface that "simplified" the look of Gmail into a more minimalist design to provide a more consistent look throughout its products and services as part of an overall Google design change. Majorly redesigned elements included a streamlined conversation view, configurable density of information, new higher quality themes, a resizable navigation bar with always visible labels and contacts, and better search. Users were able to preview the new interface design for months prior to the official release, as well as revert to the old interface, until March 2012, when Google discontinued the ability to revert and completed the transition to the new design for all users. In May 2013, Google updated the Gmail inbox with tabs which allow the application to categorize the user's emails. The five tabs are: Primary, Social, Promotions, Updates, and Forums. In addition to customization options, the entire update can be disabled, allowing users to return to the traditional inbox structure. In April 2018, Google introduced a new web UI for Gmail. The new redesign follows Google's Material Design, and changes in the user interface include the use of Google's Product Sans font. Other updates include a Confidential mode, which allows the sender to set an expiration date for a sensitive message or to revoke it entirely, integrated rights management and two factor authentication. On 16 November 2020, Google announced new settings for smart features and personalization in Gmail. Under the new settings users were given control of their data in Gmail, Chat, and Meet, offering smart features like Smart Compose and Smart Reply. On 6 April 2021, Google rolled out Google Chat and Room (early access) feature to all Gmail users. On 28 July 2022, Google rolled out Material You to all Gmail users.

Gmail's spam filtering features a community driven system: when any user marks an email as spam, this provides information to help the system identify similar future messages for all Gmail users. In the April 2018 update, the spam filtering banners got a redesign, with bigger and bolder lettering.

The Gmail Labs feature, introduced on June 5, 2008, allows users to test new or experimental features of Gmail. Users can enable or disable Labs features selectively and provide feedback about each of them. This allows Gmail engineers to obtain user input about new features to improve them and also to assess their popularity. Popular features, like the "Undo Send" option, often "graduate" from Gmail Labs to become a formal setting in Gmail. All Labs features are experimental and are subject to termination at any time.

Gmail incorporates a search bar for searching emails. The search bar can also search contacts, files stored in Google Drive, events from Google Calendar, and Google Sites. In May 2012, Gmail improved the search functionality to include auto complete predictions from the user's emails. Gmail's search functionality does not support searching for word fragments (also known as 'substring search' or partial word search). Workarounds exist.

In October 2012, Google added over 100 virtual keyboards, transliterations, and input method editors to Gmail, enabling users different types of input styles for different languages in an effort to help users write in languages that are not "limited by the language of your keyboard." In October 2013, Google added handwriting input support to Gmail. In August 2014, Gmail became the first major email provider to let users send and receive emails from addresses with accent marks and letters from outside the Latin alphabet.

The modern AJAX version is officially supported in the current and previous major releases of Google Chrome, Firefox, Microsoft Edge and Safari web browsers on a rolling basis. Gmail's "basic HTML" version works on almost all browsers. This version of Gmail has been discontinued from January 2024. In August 2011, Google introduced Gmail Offline, an HTML5 powered app for providing access to the service while offline. Gmail Offline runs on the Google Chrome browser and can be downloaded from the Chrome Web Store. In addition to the native apps on iOS and Android, users can access Gmail through the web browser on a mobile device.

Gmail has native applications for iOS devices (including iPhone, iPad, and iPod Touch) and for Android devices. In November 2014, Google introduced functionality in the Gmail Android app that enabled sending and receiving emails from non Gmail addresses (such as Yahoo! Mail and Outlook. com) through POP or IMAP. In November 2016, Google redesigned the Gmail app for the iOS platform, bringing the first complete visual overhaul in "nearly four years". The update added much more use of colors, sleeker transitions, and the addition of several "highly requested" features, including Undo Send, faster search with instant results and spelling suggestions, and Swipe to Archive/Delete. In May 2017, Google updated Gmail on Android to feature protection from phishing attacks. Media outlets noticed that the new protection was announced amid a widespread phishing attack on a combination of Gmail and Google's Docs document service that occurred on the same day. Inbox by Gmail, another app from the Gmail team, was also available for iOS and Android devices. It was discontinued in April 2019. Third party programs can be used to access Gmail, using the POP or IMAP protocols. In 2019, Google rolled out dark mode for its mobile apps in Android and iOS.

In October 2014, Google introduced Inbox by Gmail on an invitation only basis. Developed by the Gmail team, but serving as a "completely different type of inbox", the service is made to help users deal with the challenges of an active email. Citing issues such as distractions, difficulty in finding important information buried in messages, and receiving more emails than ever, Inbox by Gmail has several important differences from Gmail, including bundles that automatically sort emails of the same topic together, highlights that surface key information from messages, and reminders, assists, and snooze, that help the user in handling incoming emails at appropriate times. Inbox by Gmail became publicly available in May 2015. In September 2018, Google announced it would end the service at the end of March 2019, most of its key features having been incorporated into the standard Gmail service. The service was discontinued on April 2, 2019.

In August 2010, Google released a plugin that provides integrated telephone service within Gmail's Google Chat interface. The feature initially lacked an official name, with Google referring to it as both "Google Voice in Gmail chat" and "Call Phones in Gmail". The service logged over one million calls in 24 hours. In March 2014, Google Voice was discontinued, and replaced with functionality from Google Hangouts, another communication platform from Google. On February 9, 2010, Google commenced its new social networking tool, Google Buzz, which integrated with Gmail, allowing users to share links and media, as well as status updates. Google Buzz was discontinued in October 2011, replaced with new functionality in Google+, Google's then new social networking platform. Gmail was integrated with Google+ in December 2011, as part of an effort to have all Google information across one Google account, with a centralized Google+ user profile. Backlash from the move caused Google to step back and remove the requirement of a Google+ user account, keeping only a private Google account without a public facing profile, starting in July 2015. In May 2013, Google announced the integration between Google Wallet and Gmail, which would allow Gmail users to send money as email attachments. Although the sender must use a Gmail account, the recipient does not need to be using a Gmail address. The feature has no transaction fees, but there are limits to the amount of money that can be sent. Initially only available on the web, the feature was expanded to the Android app in March 2017, for people living in the United States. In September 2016, Google released Google Trips, an app that, based on information from a user's Gmail messages, automatically generates travel cards. A travel card contains itinerary details, such as plane tickets and car rentals, and recommends activities, food and drinks, and attractions based on location, time, and interests. The app also has offline functionality. In April 2017, Google Trips received an update adding several significant features. The app now also scans Gmail for bus and train tickets, and allows users to manually input trip reservations. Users can send trip details to other users' email, and if the recipient also has Google Trips, the information will be automatically available in their apps as well.

Google has supported the secure HTTPS since the day it launched. In the beginning, it was only default on the login page, a reason that Google engineer Ariel Rideout stated was because HTTPS made "your mail slower". However, users could manually switch to secure HTTPS mode inside the inbox after logging in. In July 2008, Google simplified the ability to manually enable secure mode, with a toggle in the settings menu. In 2007, Google fixed a cross site scripting security issue that could let attackers collect information from Gmail contact lists. In January 2010, Google began rolling out HTTPS as the default for all users. In June 2012, a new security feature was introduced to protect users from state sponsored attacks. A banner will appear at the top of the page that warns users of an unauthorized account compromise. In March 2014, Google announced that an encrypted HTTPS connection would be used for the sending and receiving of all Gmail emails, and "every single email message you send or receive —100% of them —is encrypted while moving internally" through the company's systems. Whenever possible, Gmail uses transport layer security (TLS) to automatically encrypt emails sent and received. On the web and on Android devices, users can check if a message is encrypted by checking if the message has a closed or open red padlock. Gmail automatically scans all incoming and outgoing e mails for viruses in email attachments. For security reasons, some file types, including executables, are not allowed to be sent in emails. At the end of May 2017, Google announced that it had applied machine learning technology to identify emails with phishing and spam, having a 99.9% detection accuracy. The company also announced that Gmail would selectively delay some messages, approximately 0.05% of all, to perform more detailed analysis and aggregate details to improve its algorithms. In November 2020, Google started adding click time link protection by redirecting clicked links to Google in official Gmail clients.

In Google's Transparency Report under the Safer email section, it provides information on the percentage of emails encrypted in transit between Gmail and third party email providers.

Gmail supports two step verification, an optional additional measure for users to protect their accounts when logging in. Once enabled, users are required to verify their identity using a second method after entering their username and password when logging in on a new device. Common methods include entering a code sent to a user's mobile phone through a text message, entering a code using the Google Authenticator smartphone app, responding to a prompt on an Android/iOS device or by inserting a physical security key into the computer's USB port. Using a security key for two step verification was made available as an option in October 2014.

If an algorithm detects what Google calls "abnormal usage that may indicate that your account has been compromised", the account can be automatically locked down for between one minute and 24 hours, depending on the type of activity detected. Listed reasons for a lock down include:
"Receiving, deleting, or downloading large amounts of mail via POP or IMAP in a short period of time. If you're getting the error message, 'Lockdown in Sector 4,' you should be able to access Gmail again after waiting 24 hours." "Sending a large number of undeliverable messages (messages that bounce back)." "Using file sharing or file storage software, browser extensions, or third party software that automatically logs into your account." "Leaving multiple instances of Gmail open." "Browser related issues. Please note that if you find your browser continually reloading while attempting to access your Inbox, it's probably a browser issue, and it may be necessary to clear your browser's cache and cookies."

Google combats child pornography through Gmail's servers in conjunction with the National Center for Missing & Exploited Children (NCMEC) to find children suffering abuse around the world. In collaboration with the NCMEC, Google creates a database of child pornography pictures. Each one of the images is given a unique numerical number known as a hash. Google then scans Gmail looking for the unique hashes. When suspicious images are located Google reports the incident to the appropriate national authorities.

The idea for Gmail was developed by Paul Buchheit several years before it was announced to the public. The project was known by the code name Caribou. During early development, the project was kept secret from most of Google's own engineers. This changed once the project improved, and by early 2004, most employees were using it to access the company's internal email system. Gmail was announced to the public by Google on April 1, 2004, as a limited beta release. In November 2006, Google began offering a Java based application of Gmail for mobile phones. In October 2007, Google began a process of rewriting parts of the code that Gmail used, which would make the service faster and add new features, such as custom keyboard shortcuts and the ability to bookmark specific messages and email searches. Gmail also added IMAP support in October 2007. An update around January 2008 changed elements of Gmail's use of JavaScript, and resulted in the failure of a third party script some users had been using. Google acknowledged the issue and helped users with workarounds. Gmail exited the beta status on July 7, 2009. Prior to December 2013, users had to approve to see images in emails, which acted as a security measure. This changed in December 2013, when Google, citing improved image handling, enabled images to be visible without user approval. Images are now routed through Google's secure proxy servers rather than the original external host servers. MarketingLand noted that the change to image handling means email marketers will no longer be able to track the recipient's IP address or information about what kind of device the recipient is using. However, Wired stated that the new change means senders can track the time when an email is first opened, as the initial loading of the images requires the system to make a "callback" to the original server.

In June 2012, Google announced that Gmail had 425 million active users globally. In May 2015, Google announced that Gmail had 900 million active users, 75% of whom were using the service on mobile devices. In February 2016, Google announced that Gmail had passed 1 billion active users. In July 2017, Google announced that Gmail had passed 1.2 billion active users. In the business sector, Quartz reported in August 2014 that, among 150 companies checked in three major categories in the United States (Fortune 50 largest companies, mid size tech and media companies, and startup companies from the last Y Combinator incubator class), only one Fortune 50 company used Gmail – Google itself – while 60% of mid sized companies and 92% of startup companies were using Gmail. In May 2014, Gmail became the first app on the Google Play Store to hit one billion installations on Android devices.

Before the introduction of Gmail, the website of product and graphic design from Gamil Design in Raleigh, North Carolina, received 3,000 hits per month. In May 2004, a Google engineer who had accidentally gone to the Gamil site a number of times contacted the company and asked if the site had experienced an increase in traffic. In fact, the site's activity had doubled. Two years later, with 600,000 hits per month, the Internet service provider wanted to charge more, and Gamil posted the message on its site "You may have arrived here by misspelling Gmail. We understand. Typing fast is not our strongest skill. But since you've typed your way here, let's share."

Gmail is noted by web developers for its early adoption of Ajax.
