<div>A new tool for Gmail lets you revoke access to messages whenever you want. </div><div> </div><div>Dmail, a new Google Chrome plugin, gives you complete control over how long your recipient can view your email.</div><div> </div><div>When sending an email through Gmail, users can set a specific time when the message will self-destruct, ranging anywhere from an hour to a week. And even emails without a specific self-destruct timer can still be recalled by the sender at any time, making them unviewable to the recipient.</div><div> </div><div>If you don't have a predetermined time frame, pick "never" as your time frame. If you need to revoke it at a later date, you can find the email in your sent folder and do so.</div><div> </div><div>All messages are encrypted and whenever the sender restricts the right to access, the recipient will no longer be able to see the original message.</div><div> </div><div>Dmail is for those times when you're sending sensitive information, like passwords or account information meant for certain eyes only, you can set an email to self-destruct within a certain time.</div><div> </div><div>Once the message self-destructs, recipients get a message that the email is no longer available when they try to read it.</div><div> </div><div>At present, Gmail allows users to revoke sent emails. Gmail's "undo send" button only works for up to 30 seconds. Dmail gives you as much time as you like.</div><div> </div><div>Plus, Dmail claims that they will soon unlock a feature where forwarding won't work - only the intended recipient will be able to see your message.</div><div> </div><div>Although you can receive Dmail messages from any email account or client, you can only send them through Gmail on Chrome.</div><div> </div><div>Dmail only works with Gmail now, but it's likely to expand to work with other services soon, with plans to release both an iOS and Android version this fall.</div>
