What is the tightening of the return?
return return when it comes to computer, refers to the ability of the e -mail sender to receive the notification with the date and time stamp when the recipient opened the mail. The sender might want a return confirmation of course to make sure that all e -mail actually achieves its goal, or could only decide on the announcement if the post office is associated with legal or professional matters that require a forensic record. In all cases, the recipient may block the return generation, intentionally or randomly.
Today's e -mail clients have a control element on request of the refund for the mail you send and a separate check to accept or reject the required income. First, let's look at the return request.
Although it might sound clever to know when people opened mail, you need to consider several things. First, some people consider returning income invasion of their privacy. They prefer to read and answer the post office without "return timeDiny ticking. “Secondly, if you send a lot of e -mails, you can end up with income that bombard the mailbox 6 This brings us to the second control mechanism - the ability to accept or reject the request for acceptance.
If the e-mail client is configured to accept the return request, the opening of the e-mail can generate a pop-up window asking for a notification permit. Click "OK" to automatically generate time mail without further connection. However, some people are so accustomed to closing of pop -ups that could automatically click on "no" or "close" without reading the window, thus the accisbreely denies the confirmation.
For other e -mail clients, if the reception is left allowed, the program generates the income quietly in the background without any user interaction. In many cases, this check is enabled by default and peopledo not realize that their e -mail client sends return income.
If the e -mail client is configured to reject the return requirements, it will not be generated. They can still be supplied in a more secret way, but using web errors built into e-mail interfaces with HTML support.
What is an e-mail interface with HTML support? HTML is a marking language used on the web. While the e-mail was originally designed to be only for text, e-mail clients can work in two modes today: text or HTML only. Many people choose an interface supported by HTML because it is flashes, allowing you to display embedded websites, sounds and images inside e-mail messages. In principle, it is equal to visiting the website from the internal email client.
Since it is well known that many people decide to deactivate return income, they still use e-mail interfaces with HTML support, some companies offer a service to circumvent the affected income. This method requestIt dates to use the recipient in HTML and to have an open link to the Internet while the post office is open. If both of these conditions are met, income reception is generated using a web error.
Web error is inserted into e -mail as a small, invisible image holder. When the mail is open to the recipient, the image holder requires the e -mail program to contact the web and download the image. Assuming the computer is online, the web is contacted and the invisible image is downloaded. The picture itself is several transparent pixels, imperceptible to the reader, but the process burns the function of accepting the return on the web that hosts a web error. The automatic script generates a time stamp when the image has been required and sends a return receipt to the client. If everything goes according to plan, the reader will never realize that he has just tripped the process that generated a return confirmation.
Purists tend to configure their e-mail clients to use only text because it is safetymore than e-mail with HTML support. Others decide to HTML mail, but configure their e -mail client to block built -in images to avoid arbitrarily downloading web errors, viruses or other malicious scripts. However, this also means blocking legitimate images in many cases. People who use a web e-mail (websites that offer e-mail services) may not have a choice, even if some services offer the ability to block web errors.
