How to Check if an Email Address is Valid and Exists

How do you know if an email address exists or not? The easy option would be that you send a dummy mail to that email address, wait for an hour or so and if your message bounces, it is very likely that the particular email address does not exist. The approach works but wouldn’t it be nice if you could check any email address instantly without even sending that test message?
The other slightly technical option to verify an email address is by querying the mail server. You connect to the mail server through telnet (see video), enter your email address and the other email address that you are trying to verify. If the server response is an error code, the email address is probably not valid.

How to Check Email Addresses Instantly

Let me share an extremely simple method for checking if an email address is valid and exists or not.

Go to the login page of the email service and pretend that you no longer remember the password of your email account. The service will ask for your email address where they can send the password recovery instructions. Here if you enter an email address that does exist, the service is mostly likely to tell you that the particular user name does not exist. I have tested this with Google Apps, Yahoo Mail and Outlook (Hotmail) and the method works with them all.

For Gmail and Google Apps Accounts

Go to Google’s password assistance page at google.com/accounts/recovery and choose the I don’t know my password option. Enter the email address that you are trying to verify – it could be an @gmail address or a Google Apps address – and choose Continue. If that address is not valid, Google will throw an error saying No account found with that email address.

Alternatively, you can go to the Gmail Sign-up page ataccounts.google.com/SignUp and try creating a new Gmail account with the address that you are trying to verify. For valid email address, the error would saySomeone already has that username.

For Outlook, Hotmail and Live.com Addresses

Go to account.live.com/ResetPassword, choose the I forgot my password option and enter the Outlook email address. You will get an error saying The Microsoft account is incorrect. for addresses that do not exist.

For Verifying Yahoo Email Addresses

Go to Yahoo’s account recovery page at edit.yahoo.com/forgot, enter the @yahoo.com email address that you are checking for validity and click the Next button. Yahoo will say We couldn’t match the Yahoo ID you entered with information in our database if the email address does not exist.

Speed Index :: A localized app to check internet speed by location [Enriching Srilanka]

Speed Index by Mobyle, is a localized android application (for Srilankans) developed by its founder Hameedul Aqeel.  This application provides an updated average speeds of localized network providers by its location. Which means; either a user needs to key-in their preferred place to obtain DATA from or by letting the GPS track down current location (enabling GPS will track only the current location of the device).

As per the app author, He mentioned that; “This app takes all user inputs and then produce and average speed calculation of a respective service provider when a user requests the speed DATA of a location”. For example; 10 users who resides withing Mt. Lavinia submits their inputs. The app itself gather all DATA’s and produce only the average of all 10 inputs.

One advantage I see is that, none can actually complain about the inaccuracy of the displayed DATA’s since the records are mostly submitted by its end-users. Yes! you’re right, the application is not only to view results, it also has the ability to collect speed DATA’s submitted by users and produce it accordingly.

To make this more interesting, I’m sharing a tiny bio about the app author. Yes, Aqeel, is a well-known fellow colleague of mine whom I met in twitter long time ago. It may sound bit cocky.. But, trust me… he was one of the best guys whom I came across. Further, this proves that all characters (or you may call strangers) who you meet online (especially in twitter) aren’t actually bad as we think. All you have to do is put on a trust and have a chat.

How I see Aqeel is that he always comes up with crazy ideas to build and develop applications, websites.. etc. The reason is that he sees the technology in different aspects and loves combining them together to produce something creative. Another great quality that I find within him is that he loves user feedback’s before he finalize a project though he don’t socialize in deep. But I must confess that he’s a good friend & trustworthy fellow to be around with. Aqeel is also a grad who’s currently reading for his degree program in Computer systems and networks at SLIIT. A lad who has good potential into designing & developing web/software contents.

Shoot him an e-mail or keep in touch with him via available social networks. I’m sure he’ll help you out with anything and everything related to his developments. You can reach him via his web portfolio here.

All images which were posted on this page are owned by it producer Mobyle. These aren’t the screen taken by myself as the app isn’t available for non-srilankan fellows. I couldn’t test it for myself as I’m not residing currently in Srilanka. But I can assure that the app does its magic as I got positive feedback’s from my fellow colleagues.

Geek Opinion: Over-all app is fascinating & working great without any leakage. Even the app performs promising as we heard some positive feedbacks. Speed Index is on its early stage as per the app author (mentioned while on a hangout) where he promised on new features such as upload speed, tab support, cross platform support & many more.
