Hey Guys, I have got this hidden features from an article. So, I thought it may help for few people who are not fully aware of Gmail. 1.) Handling spam in Gmail: Did you know that the dots within your Gmail address have no significance? So if your address is [email protected], it means that any emails which are sent to [email protected], or [email protected], or even [email protected] will also land in your inbox. So, what's the use of this 'Gmail glitch'? Well, you can use it to set up filter rules for your internet subscription services or one-time online registrations. For example, if you do not want to provide your real email address to sign up for an online service, simply use an alias like [email protected] and then create an email filter to delete all messages that come to this ID. 2.) Sorting through email subscriptions If you want to create a filter for your various internet subscriptions, you can use the '+' feature. Say you want to subscribe to a newsletter from The Onion, you can use [email protected]. The newsletters will still come to your inbox, but you can now use 'theonion' as a keyword to search for all your tagged emails, and even set filters. 3.)Managing contacts Did you know that you can have your smartphone contacts synced automatically with your Google account? In effect, you will only need to maintain the 'Contacts' on Gmail for your whole address book to be updated on your smartphone and tablet where you've signed-in with your ID. 4.)To sync your contacts On an Android device, go to Settings > Add Account > Google and follow the steps to add your ID. After this, every time you add a new contact, make sure you it is added to your Google account and not saved locally to your smartphone. After you save the number to your Google ID, it will be synced to your Gmail address book and will be reflected on all other devices that have the same account. Similarly, you can sync contacts on iOS, Windows Phone and BlackBerry devices, though the steps will differ slightly. 5.)Google 18 Click Gmail in the top left corner, choose Contacts, then More > Find & Merge Contacts. You will get a list of all the double entries in your address book. Choose the ones you would like to combine and click Merge. 6.)Restore addresses When you delete contacts from your mobile device, they will be removed from your Google account as well. But you can still recover them within 30 days of deleting. Go to Contacts, click More > Restore contacts. Choose the time you would like to revert to, and click Restore. 7.)To create an email filter Click on the gear symbol in the top right corner of your Gmail inbox, then, go to Settings > Filter tab > Create a new filter. Choose your criteria (From, To, Includes the words, Has attachment etc) for the filter. Click Create Filter with this search and you can then choose an action like Skip the Inbox (Archive it), Apply the Label, Delete It and more. There! Now, all your emails will be sorted and dealt with according to the filter actions you have chosen. 8.)Labs Programmers at Google have created experimental stuff that can do wonders for your email experience. For example, you could use a Labs option called Right-side chat to move your chat list from the left pane to the other side. 9.)Managing your dates Using your Google ID you can create a planner using its calendar feature at calendar.google.com. Here, you can add and view events and meetings you have scheduled by day, week, month, or as an easy-to-read list of your daily agenda. As these are Hidden Features I am posting it in the Black Hat section. Please make a view and try these features too.
