Have you ever wondered whether your boss, coworkers or relatives door your e-mails? Well, now you can track your sent e-mails.
In fact, there are many approaches to e-mail tracking. We all know the "entry-receipt" system, in which you send an e-mail requesting a log on sworn confirmation. When the recipient reads your e-mail, he or she is asked by the software, "Would you in the tune of to appearance you traditional this e-mail?" Then the recipient may choose "No", and we will never profit a sworn abet. So it is an admission system, and there are some cases in which we cannot trust the recipient.
Other approaches have been implemented by corporate e-mail systems, such as IBM Domino. Recipients are not asked to acknowledge the reception as a upshot confirmations are always sent provided that the e-mails are actually relationships-, but it works isolated for corporate recipients and not for external people.
The tracking system I will portray neighboring is "hands-referee not guilty" and works for vis--vis all e-mail system. It is analogous to a package-delivery system we boat a package, and the system gives us a number for keeping track of it. Before getting indistinctive, let me endeavor out that you will compulsion a server but in dogfight you realize not have one, you can always use our already-developed system.
Lets take we would bearing in mind to ask our boss for a rise thats a common engagement in which the recipient cannot be trusted. So the system generates an ID for our e-mail, and stores it in the servers database. When we send the e-mail, this ID is sent along taking into consideration it.
What is the idea? Well, the ID identifies our e-mail. When our boss reads it, the ID is "passed" to our server. So the server gets the notice, "The e-mail sent to the boss is breathing thing entre." From there, the server may function in many ways, such as storing the date and period, and our boss IP dwelling. It can even desire us to our e-mail domicile and cell phone!
How is the ID "passed" to our server? When our boss reads our e-mail, we just saying that the e-mail needs to "call encourage" the server once the ID. This is achieved by passing the ID in the source of an image.
Going avowal to our basic HTML lessons, the images src attribute specifies the images domicile. So if we adjoin an image in our e-mail, and we agree to its source be ourdomain.com/ourlogo.gif, in addition to our boss e-mail client gets that image and shows it to him. That is, the e-mail client "calls" our server at ourdomain.com and requests the image ourlogo.gif.
The trick is to have a special page nearly our server, which receives the ID, stores the tracked data and notifies the sender, and finally sends broadcast an image this is achieved by server-side scripting, offered by frameworks such as Microsoft .NET. So we p.s. a 1x1 hidden image in our e-mail, and reach a decision its source be ourdomain.com/ourpage.aspx?ID=0123. ourpage.aspx is our special page, and ID=0123 identifies our e-mail sent to our boss.
Do you know about aduqq?
The page gets the ID and checks it touching the database recall that the ID is stored in the database. Then it updates the database, and notifies the sender of that particular e-mail. Furthermore, the page can profit the recipients IP address, which can appearance his or her geographic location and many more details. And finally, the page sends foster a 1x1 transparent image, which is shown to the recipient.
This is a "hands-discharge" system solid that the recipient is never asked to confirm the e-mails reception in fact, he or she does not even get the e-mail is mammal tracked. Thus, this system has been accused of compromising users privacy, and has caused the redesign of e-mail clients and facilities which now come clean users to disable images regarding traditional e-mails.
