If you ever wondered whether mails you sent ever gets read or just sent to trash, you can use a mail tracking service like MailTracking.com which allows email tracking.
They send you a email notification whenever the recipient reads your email. Notification includes many details including following…
* Date and time opened
* Location of recipient (per their ISP city /town)
* How long the email was read for
* How many times your email was opened
* If your email was forwarded, or opened on a different computer

Now how to use this service in simplest way…

Create an account with them first.
Then next time, whenever you send mail to abc@xyz.com just add .mailtracking.com to the email address. So in this case email address will become abc@xyz.com.mailtracking.com
Now whenever abc@xyz.com read your email, you will receive notification mail from mailtracking.comHow it works…
* Basically the change in email address will route email through mailtracking.com' server.
* They add a small (around 3×3 pixel) white image which is almost invisible to human eyes in email body. The image will be hosted on mailtracking servers and a unique image is kept for each email message.
* So when someone opens email that image also get downloaded. Now mailtracking server logs the browser request for image (note that the request goes in background) and thus can mail you details which mentioned above.

Note:MailTracking.com is not free. You can start with free account as I did. You get 25 credits(1 credit = 1 email) in free account.
Till then enjoy
