Privacy

Google automatically scans emails to add context-sensitive advertisements to them. Privacy advocates raised concerns that the plan involved scanning their personal, private emails and that this was a security problem. Allowing email content to be read, even by a computer, raises the risk that the expectation of privacy in email will be reduced. Furthermore, email that non-subscribers choose to send to Gmail accounts is scanned by Gmail as well, even though those senders never agreed to Gmail's terms of service or privacy policy. Google can change its privacy policy unilaterally and Google is technically able to cross-reference cookies across its information-rich product line to make dossiers on individuals. However, most email systems make use of server-side content scanning in order to check for spam.

In 2004, privacy advocates also regard the lack of disclosed data retention and correlation policies as problematic. Google has the ability to combine information contained in a person's email messages with information from Internet searches. Google has not confirmed how long such information is kept or how it can be used. One of the concerns is that it could be of interest to law enforcement agencies. More than 30 privacy and civil liberties organizations have urged Google to suspend Gmail service until these issues are resolved.

Gmail's privacy policy used to contain the clause: "residual copies of deleted messages and accounts may take up to 60 days to be deleted from our active servers and may remain in our offline backup systems". However, this statement does not appear in Gmail's current privacy policy. Less specifically, Google have stated that they will "make reasonable efforts to remove deleted information from our systems as quickly as is practical."

Google defends its position by citing their use of email-scanning to the user's benefit. Google states that Gmail refrains from displaying ads next to potentially sensitive messages such as those that mention tragedy, catastrophe, or death.

Gmail accounts of human rights activists in China were hacked in sophisticated attacks — thought to use phishing and exploit a vulnerability in Internet Explorer — in late 2009. Any (web mail or other) mail system which stores and retains user's email contents is an attractive target for such attacks, but Gmail is popular with security-conscious users because of its early HTTPS secure (encrypted) connection support, and its more-recent HTTPS-only default setting.

The launch of Google Buzz as an opt-out social network immediately drew criticism for violating user privacy because it automatically allowed Gmail users' contacts to view their other contacts. Buzz was discontinued in December of 2011.

In July 2012 Some California residents filed a lawsuit against Google and Yahoo! claiming that they illegally intercept emails sent by individual non-Gmail and non-subscribers to Gmail and Yahoo subscribers without their knowledge, consent or permission.

Technical limitations

Gmail does not allow users to send or receive executable files or archives containing executable files if it recognizes the file extension as one used for executable files or archives.
By design, Gmail does not deliver all of a user's emails. When downloading mail through POP or IMAP access, Gmail fails to deliver messages that users have sent to themselves if the client has a copy of it already. It also does not deliver to a user's inbox (via any access interface) those messages that users have sent to mailing lists and which they might expect to receive back via the mailing list.

Before September 29, 2010, Gmail sorted email only by conversations (threads), which can be a problem for large conversations. For example, if a user sends a query to a large group of people, all of the responses are stored in a single conversation that is impossible to break apart. There is no way to search for responses from one user without getting the entire conversation. While deletion of individual emails is possible, most operations, such as archiving and labeling, can be performed only on whole conversations. Conversations cannot be split up or combined.[83] As a result of complaints from some users, Google made conversation view optional starting September 29, 2010.

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. People who rely entirely on Gmail for business purposes complained about these outages.[85][86] Another outage occurred on September 1, 2009. Later that day, a Google vice president, Ben Treynor, explained that the problem, which ultimately resulted in about 100 minutes of outage, was caused by overloaded routers, triggered by a routine configuration change which added more router load than expected. Treynor wrote, "Gmail remains more than 99.9% available to all users, and we're committed to keeping events like today's notable for their rarity."

In 2009, Google continued to experience outages across its network, leaving users without access to their email, calendars, and virtual files.
