Gmail is a free, advertising-supported internet message service supplied by Google. Users may get get access to to Gmail as secure webmail, as well as by burst3 or IMAP4 protocols.[7][8] Gmail primarily begun as an invitation-only beta issue on April 1, 2004 and it became accessible to the general public on February 7, 2007, though still in beta rank at that time. The service was upgraded from beta status on July 7, 2009, along with the rest of the Google Apps suite.
With an initial storage capability offer of 1 GB per user, Gmail significantly increased the webmail benchmark for free storage from the 2 to 4 MB its competitors such as Hotmail suggested at that time. one-by-one Gmail notes, encompassing attachments, may be up to 25 MB, which is bigger than many other mail services support. Gmail has a search-oriented interface and a "conversation outlook" alike to an Internet forum. Gmail is noted by world wide web developers for its pioneering use of Ajax. Gmail runs on Google GFE/2.0 on Linux. As of June 2012, it is the most widely used web-based internet message provider with over 425 million active users worldwide. 

Features
Storage
Gmail's log-in page (September 2011)
On April 1, 2005, the first anniversary of Gmail, Google announced an increase from 1 GB. Georges Harik, the product management director for Gmail, stated that Google would "keep giving people more space forever."
On April 24, 2012, Gmail announced the increase of free storage in Gmail from 7.5 GB to 10 GB ("and counting") as part of the launch of Google Drive. At the same time, Gmail users became unable to upgrade the size of their e-mail inbox beyond a 30GB limit, irrespective of their price plan.
On May 13, 2013 Google announced the merge of their free storage across Gmail, Google Drive, & Google+ Photos allowing users up to 15GB of free storage to use across their accounts.
As of September 2013, the Gmail service provides 15 GB of free storage per account. Users can rent additional storage (shared between Picasa Web Albums, Google Drive and Gmail) from 100 GB (US$4.99/month) to 16 TB (US$799.99/month).

Gmail Labs
The Gmail Labs feature, introduced on June 5, 2008, allows users to test new or experimental features of Gmail, such as bookmarking of important email messages or custom keyboard shortcuts. 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 and whether they merit developing into regular Gmail features. All Labs features are experimental and are subject to termination at any time. 

Spam filter
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. Users may tune the system to allow mail marked as spam to be handled in particular ways.

Gmail Mobile
Gmail wireless is a version of Google's Gmail email service. It was released on December 16, 2005, and is available in more than 40 dialects. It is a free service, evolved to provide get get get access to to to to Gmail from mobile apparatus such as cell teletelephones, or smartphones. Gmail wireless offers many of the characteristics as Gmail consigned competently to smaller, wireless screens. Users have the ability to create, read, archive, reply, forward, assess unread, add a celebrity, add made-to-order marks or trash email notes. On September 22, 2009 Google conveyed impel Mail support to its Gmail service using Google Sync for iPhone and iPod feel stages.
In order to use the service a client will need a Gmail account and a mobile apparatus that encounters the following requirements:
Social networking

On February 9, 2010, Google commenced their new service, Google Buzz, which integrated with Gmail allowing users to share links and media, as well as status updates.[32] Buzz was launched with an automatic opt-in, causing an uproar in the Gmail community which led Google to quickly undo its initial moves. Buzz was discontinued in December 2011 in favor of Google+.
Google+, which was launched on June 28, 2011 as Google's most recent foray into social networking, integrates further into Gmail than Google Buzz, with Google+ profile icons appearing in the headers of emails received in Gmail and Google+ circles appearing in sortings of Gmail contacts. As of August 2012, Gmail's video chat is replaced with Google+ Hangouts for multi-user videoconferencing.

Google Voice in Gmail chat
In August 2010, Google released a plugin that provides integrated telephone service inside Gmail's Google brief talk interface. This service initially lacked an authorized title, with Google mentioning to it as "Google Voice in Gmail chat" and furthermore "Call Phones in Gmail", but is now called Google Video and Voice Chat. The service allows people to make free calls from their Gmail account to U.S. and Canada, at smallest through the end of 2012. Gmail account users can furthermore call other nations on a charge cornerstone. The service logged over 1 million calls in 24 hours on 26 August 2010.
Google Voice multi-way videoconferencing (with support for document sharing) is now integrated with Google+ Hangouts. 

Offline Google Mail
On August 31, 2011, it was announced on the Official Gmail Blog that Offline Google Mail was launched as a Chrome web app at the Google Chrome Web Store. This HTML5-powered app is based on the Gmail web app on tablets.
On April 11, 2011, Google engineer Sundar Pichai revealed that Google employees had been testing the app together with offline versions of Google Docs and Google Calendar for months and that the apps would be launched in the summer of 2011. 

Gmail Search
Gmail has an integrated search function that resembles Google Search but only searches a user's Gmail account. On May 21, 2012, Gmail improved their search functionality to include autocomplete predictions from the user's email content. As with a web search, Gmail's search functionality cannot search for word fragments, although it does perform partial-string stemming (e.g. searching for 'month' will turn up an email that includes the term 'months').

Extra security features
When creating a Gmail account, users are asked to provide a recovery email address—to allow them to reset their password if they have forgotten it, or if their account is hacked. In some countries, such as the United States, the United Kingdom and India, Google may also require one-time use of a mobile phone number to send an account validation code by SMS text messaging or voice message when creating a new account. This requirement to associate a unique recovery email and/or phone number with an account makes it difficult for would-be spammers to set up multiple accounts.
Google also offers a 2-step verification option—for extra security against hacking—that requests a validation code each time the user logs into their Google account. The code is either generated by an application ("Google Authenticator") or received from Google as an SMS text message, a voice message, or an email to another account. Trusted devices can be "marked" to skip this 2-step log-on authentication. When this feature is switched on, software that cannot provide the validation code (e.g. IMAP and POP3 clients) must use a unique 16-character alphanumeric password generated by Google instead of the user's normal password. 

Security Warnings
On June 5, 2012, a new security feature was introduced to protect users from state-sponsored attacks. Whenever Google analyses indicate that a government has attempted to compromise an account, Gmail will display a notice that reads "Warning: We believe state-sponsored attackers may be trying to compromise your account or computer".

Money Transfer
At Google I/O 2013 on May 15, 2013, Google announced a feature, which allows Gmail users to send money via Google Wallet as email attachments. Google plans to roll out the feature "over the coming months".

Interface
The Gmail user interface differs from other Webmail systems with its focus on search and its "conversation view" of email, grouping several replies onto a single page. Gmail's user-experience 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. In 2008, Fox left Gmail for a position at Yahoo. 

History
The idea for Gmail was pitched by Rajen Sheth during an interview with Google, and went on to be developed by Paul Buchheit several years before it was announced to the public. Initially the email client was available for use only by Google employees internally. Google announced Gmail to the public on April 1, 2004. IMAP support was added on October 24, 2007. 

Domain name history

As of June 22, 2005, Gmail's canonical URI changed from http://gmail.google.com/gmail/ to http://mail.google.com/mail/. As of December 2012, those who typed in the former URI were redirected to the latter.

April Fools' jokes
On April Fools' Day 2007, Google made fun of paper-based archiving by inserting "Gmail Paper", where a client could click a button and Gposted letters would purportedly posted letters an ad-supported paper exact replicate internet message archive for free.
On April Fools' Day 2008, Google introduced a false service, "Gmail Custom Time", which claimed to permit a user to drive up to ten emails per year with forged timestamps. The hoax asserted that by bending spacetime on the Google servers, the internet messages really get routed through the fourth dimension of time itself before reaching their proposed recipient.
On April Fools' Day 2009, Google introduced a service called Gmail Autopilot by CADIE. According to Google, the service purported to automatically read and reply to emails for the client. It emerged to work by investigating messages for the strong feelings expressed in the note and either providing recommendations to the client or mechanically responding to the note.
On April Fools' Day 2011, Google presented a service called Gmail shift which allowed users to navigate internet messages, drive and even dictate notes through the user's physical actions using webcams. For demonstration, to send an internet message, the client would present the activity of licking a stamp, and posting it. After the user signed up, they would be administered to an "April Fools'" message.
On April Fools' Day 2012, Google presented a service called Gmail Tap, an submission for Android and iOS which asserted to twice typing pace with a revolutionary new keyboard. The system involves a keyboard with three keys: Morse cipher "dash" and "dot", and a spacebar (along with backspace). soon before midnight, on stride 31, 2012 Gmail Tap was supplemented, an Android submission utilizing Morse cipher rather than of the onscreen keyboard. choosing Download App for Your telephone made the message: "Oops! Gmail Tap is a bit too well liked right now. We propose you try downloading it afresh on April 2nd."
On April Fools' Day 2013, Google introduced a service renowned as Gmail Blue, where an application that would allow Gmail to have added characteristics and become totally azure colored. 

Code changes
Gmail's interface was rewritten in the middle of 2007 and was released to users starting on October 29, 2007. The new version had a redesigned contacts section, quick contacts box and chat popups, which were added to names in the message list as well as the contact list. The contacts application is integrated into other Google services, such as Google Docs. Users granted access to the new version were given a link at the top-right corner which read "Newer Version". As of December 2007, most new registrations in English (US) along with most pre-existing accounts are given the new interface by default when supported.
These coding changes mean that only users of Internet Explorer 7, Firefox 2, Google Chrome and Safari 3.0 (or more recent versions) are officially supported by Gmail and can fully use the new code. Opera 9.5 and more recent versions are not officially tested but are expected to "work with all of Gmail's features". Internet Explorer 5.5+, Netscape 7.1+, Mozilla 1.4+, Firefox 0.8, Safari 1.3 and some other browsers will give limited functionality. Other browsers may be redirected to the basic-HTML-only version of Gmail.
During the week of January 18, 2008, Google released an update that changed the way Gmail loads JavaScript. This caused the failure of some third-party extensions.
On December 12, 2008, Gmail added support for faster PDF viewing within the browser.
When Internet Explorer 10 had been available for several months, Google removed support for Google Apps for Internet Explorer 8 and older versions.
Gmail was one of the first Google projects to begin using Closure Library, part of Closure Tools, which were later open sourced. Much of the core library was developed concurrently with the 2008 update. 

Criticism
Privacy

Google mechanically scans emails to add context-sensitive advertisements to them and to filter spam. Privacy advocates increased anxieties that the design engaged scanning their individual, personal emails and that this was a security problem. permitting internet message content to be read, even by a computer, raises the risk that the expectation of privacy in internet message will be reduced. Furthermore, internet message that non-subscribers select to drive to Gmail anecdotes is scrutinized by Gmail as well, even though those senders not ever acquiesced to Gmail's periods of service or privacy policy. Google can change its privacy principle unilaterally and Google is mechanically able to cross-reference cookies over its information-rich merchandise line to make dossiers on persons. However, most internet message systems make use of server-side content scanning in alignment to ascertain for spam, and of course any internet message scheme should get get access to to internet message content merely to brandish it to the client.
In 2004, privacy supports furthermore regard the need of revealed facts and figures retention and association principles as awkward. Google has the proficiency to blend data contained in a person's internet message notes with data from Internet explorations. Google has not confirmed how long such data is kept or how it can be used. One of the anxieties is that it could be of interest to regulation enforcement agencies. More than 30 privacy and municipal liberties associations have urged Google to hover Gmail service until these matters are resolved.
Gmail's privacy principle utilised to comprise the clause: "residual copies of deleted notes and anecdotes may take up to 60 days to be deleted from our hardworking servers and may stay in our offline backup systems". However, this declaration does not appear in Gmail's present privacy principle. Less specifically, Google has stated that they will "make sensible efforts to remove deleted data from our schemes as rapidly as is practical."
Google fights back its place by citing their use of email-scanning to the user's advantage. Google states that Gmail refrains from displaying publicity next to possibly perceptive notes such as those that mention tragedy, catastrophe, or death.
Gmail accounts of human privileges activists in China were hacked in sophisticated attacks — considered to use phishing and exploit a vulnerability in Internet Explorer — in late 2009. Any (web posted letters or other) mail scheme which shops and keeps user's email contents is an attractive goal for such attacks, but Gmail is popular with security-conscious users because of its early HTTPS protected (encrypted) attachment support, and its more-recent HTTPS-only default setting.
The launch of Google Buzz as an opt-out communal network directly drew criticism for violating user privacy because it mechanically permitted Gmail users' contacts to outlook their other contacts. Buzz was discontinued in December 2011.
In stride 2011 a former Gmail user in Texas litigated Google, asserting that its Gmail service violates users' privacy by scanning e-mail messages to assist relevant ads.
In July 2012, some California inhabitants filed two class action lawsuits against Google and Yahoo! asserting that they unlawfully intercept internet messages dispatched by one-by-one non-Gmail or non-Yahoo! subscribers to Gmail and Yahoo! subscribers without their knowledge, consent or consent. A shift filed by Google's lawyers in the case accepts that Gmail users have "no legitimate expectation of privacy".
A court filing uncovered by advocacy group buyer Watchdog in August 2013 revealed that Google asserted in a court filing that no "reasonable anticipation" exists amidst Gmail users in consider to the assured confidentiality of their internet messages. In answer to a lawsuit filed in May 2013, Google clarified:
"... all users of email must inevitably anticipate that their internet messages will be subject to automated processing ... Just as a sender of a note to a business associate cannot be shocked that the recipient's assistant undoes the note, people who use web-based email today cannot be shocked if their communications are processed by the recipient's ECS [electronic communications service] provider in the course of delivery.
A Google spokesperson asserted to the media on August 15, 2013 that the company takes the privacy and security concerns of Gmail users "very seriously." 

Technical limitations
Gmail does not permit users to drive or obtain executable documents or archives containing executable documents if it recognizes the document elongation as one utilised for executable documents or archives.
By design, Gmail does not consign all of a user's eposted letterss. When downloading posted letters through burst or IMAP access, Gposted letters falls short to deliver notes that users have sent to themselves if the client has a exact replicate of it already. It also does not consign to a user's inbox (via any get get access to to interface) those notes that users have dispatched to mailing registers and which they might expect to obtain back via the mailing list.
Gmail normally kinds internet message only by conversations (threads), which can be a difficulty for large dialogues. For demonstration, if a user sends a query to a large group of persons, all of the answers are retained in a single dialogue that is unrealistic to break apart. There is no way to seek for answers from one user without getting the entire dialogue. While deletion of one-by-one emails is possible, most procedures, such as archiving and labeling, can be presented only on whole dialogues. dialogues will not be split up or blended. As a outcome of accusations from some users, Google made dialogue outlook optional beginning September 29, 2010, but there is actually no method to divide one-by-one conversations. 

Outages
Gmail has been unavailable on several occasions. On February 24, 2009, the Gmail service was offline for 2 hours and 30 minutes, preventing millions of users from accessing their accounts. persons who rely entirely on Gmail for enterprise reasons complained about these outages. Another outage occurred on September 1, 2009. subsequent that day, a Google vice leader, Ben Treynor, explained that the difficulty, which finally produced in about 100 minutes of outage, was initiated by overloaded routers, triggered by a usual configuration change which added more router burden than expected. Treynor composed, "Gmail continues more than 99.9% accessible to all users, and we're pledged to keeping events like today's notable for their rarity."
In 2009, Google continued to experience outages over its mesh, leaving users without get get access to to to their email, calendars, and virtual documents. Gmail faced another downtime on March 2, 2013 before Noon Time for many of its users. It took 16 minutes for Google to retrieve from this outage. Gmail on mobile and Google's Apps rank Dashboard were the other two skilled the identical issue throughout the time.

Twenty-four hour lockdowns
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."[116]
  • "Sending a large number of undeliverable messages (messages that bounce back)."[116]
  • "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." 
  •  
On behalf of
Prior to July 2009, any email sent through the Gmail interface included the Gmail.com address as the "sender", even if it was sent with a custom email address as "from". For example, an email sent with an external "from" address using Gmail could be displayed to a receiving email client user as From user@gmail.com on behalf of user@OtherDomainEmailAddress.com (the display used by versions of Microsoft Outlook). By exposing the Gmail address, Google claimed that this would "help prevent mail from being marked as spam". A number of Gmail users complained that this implementation was both a privacy concern and a professionalism problem.
On July 30, 2009, Gmail announced an update to resolve this issue. The updated custom 'From:' feature allows users to send messages from Gmail using a custom SMTP server, instead of Gmail's. However, the issue is still present for users whose custom email address is a second Gmail account, rather than an account on a separate domain.
Reception
Awards
Gmail was ranked second in PC World's "100 Best Products of 2005", behind Mozilla Firefox. Gmail also won 'Honorable Mention' in the Bottom Line Design Awards 2005. In September 2006, Forbes magazine declared Gmail as the best webmail. In November 2006, Gmail received PC World's 4 star rating. 

Trademark disputes
Germany

The present Google Mail logo
On July 4, 2005 Google announced that Gmail Deutschland would be rebranded as Google posted letters. The domain gmail.com became unavailable in Germany due to trademark disputes, in which cases users must use the domain googlemail.com. From that issue ahead, tourists originating from an IP address determined to be in Germany would be forwarded to googlemail.com where they could obtain an internet message address encompassing the new domain.
The domains are interchangeable so users obliged to use the googlemail.com domain are unable to select addresses currently selected by gmail.com users. Inbound emails dispatched to either googlemail.com or gmail.com locations will come to the client. When listing for an online service, Google Mail users should use the googlemail.com pattern of their internet message address to double-check that any administrative internet messages they send to the service, such as confirmation notes, are recognized.
The German calling topic is due to a trademark dispute between Google and Daniel Giersch, who owns a German company called "G-mail" which provides the service of printing out email from senders and sending the print-out by postal posted letters to the proposed recipients. On January 30, 2007, the EU's Office for Harmonization in the Internal Market directed in favor of Giersch.
Google spoofed proposing" the identical service in the Gmail Paper April Fool's Day antic in 2007.
On April 13, 2012, Google obtained the right to the Gmail trademark in Germany. On this day the gmail.de domain and the Gmail trademark were moved to Google. 

Poland
In February 2007 Google filed legal action against the owners of gmail.pl, a poet group known in full as Grupa Młodych Artystów i Literatów abbreviated GMAiL (literally, "Group of Young Artists and Writers"). This lawsuit was lost but the website no longer exists. 

Russian Federation
A Russian paid mail redirect service called gmail.ru owns the "Gmail" trademark in the Russian Federation.
The gmail.ru domain name dates from January 27, 2003. 

United Kingdom
On October 19, 2005, Google voluntarily altered the joined Kingdom type of Gmail to Google posted letters because of a dispute with the UK business unaligned International buying into study.
Users who registered before the swap to Google posted letters were adept to keep their Gmail address, whereas the Gmail logo was replaced with a Google Mail logo. Users who marked up after the title change obtain a googlemail.com address, whereas a reverse of either in the dispatched email will still consign it to the same location.
In September 2009 Google began to change the branding of UK anecdotes back to Gmail following the tenacity of the trademark argument.
On May 3, 2010, Google announced that they would start to stage out the googlemail.com domain in the UK. living users will get the option to switch to gmail.com, while new users will be given a gmail.com address by default. This furthermore needed Android phone users to perform a manufacturer reset (requiring a back-up to prevent facts and figures decrease) to refurbish phone functionality. 

Competition
After Gmail's primary development and launch, numerous living web mail services quickly advanced their storage capability.
For demonstration, Hotmail advanced space for some users from 2 MB to 25 MB, with 250 MB after 30 days, and 2 GB for Hotmail in addition to anecdotes. Yahoo! Mail went from 4 MB to 100 MB and 2 GB for Yahoo! posted letters in addition to accounts. Yahoo! posted letters storage then advanced to 250 MB and in late April 2005 to 1 GB. Yahoo! posted letters broadcast that it would be providing "unlimited" storage to all its users in March 2007 and started supplying it in May 2007.
These were all glimpsed as moves to stop existing users from swapping to Gmail and to capitalize on the newly renewed public interest in world wide web posted letters services. The yearn to catch up was particularly noted in the case of MSN's Hotmail, which upgraded its email storage from 250 MB to the new Windows reside Hotmail which includes 5 GB of storage that elaborates if essential. In November 2006, MSN Hotmail upgraded all free accounts to 1 GB of storage.
In June 2005, AOL begun providing all AIM computer display names with their own internet message anecdotes with 2 GB of storage.
Google may terminate a Gmail account after nine months of inactivity. Other webmail services have distinct, often shorter, times for marking an account as inactive. Yahoo! posted letters deactivates dormant anecdotes after four months.
As well as increasing storage limits following the launch of Gmail, Yahoo! Mail and Hotmail furthermore enhanced their internet message interfaces. During 2005, Yahoo! posted letters and Hotmail agreed Gmail's addition dimensions of 10 MB. Following the footsteps of Gmail, Yahoo! commenced the Yahoo! posted letters Beta service and Microsoft commenced Windows reside Hotmail, both incorporating Ajax interfaces. Google advanced the maximum addition dimensions to 20 MB in May 2007 and to 25 MB in June 2009.
