Answer 1

Small images called web errors are the only direct way Szere Dyeri points out, but they are more and more unhappy and are blocked by each major email client for privacy reasons. I would not consider them a reliable way to find out if E-Mail is read more.

There is a legitimate way to request confirmation by adding the following header to your email:

Disposition-Notification-To: [e-mail] 

Sending this notification may be automatically disabled by the recipient.

Answer 2

Add a small invisible image to your email content. And let the image point to the unique URL of your site. You will find out that the email opens after accessing the URL. But this will not work in email clients, which by default do not show images in letters.

I found this web service called Get Notify . They claim they do it for free, but you need to see for yourself.

Answer 3

The only way to do this is to include the image in the email that was on your server, which includes a key for the user to whom you are sending the email. For example, I send an email to the address [e-mail]. In my database (or other storage system) I have [e-mail] , which corresponds to key 0100. In his letter I include an image, for example

 <img src="http://www.myserver.com/image/?key=0100" /> 

On your server / image / you need to return an image, even 1 pixel .png. Now you have the key to which the user has been assigned, and he can act accordingly.

Answer 4

Many responded that adding a “tracking image” is a “frowning” and “considered“ dubious “activity” method.

Out of curiosity, we can say that we did not have a separate image for tracking, but we included this method in an existing image, for example, added it to your company logo, for example:

http://mycompany.com/images/logo.png?track=2742 '>

At least with this method, your tracking image will not be blocked by any scanning application.

Answer 5

One legitimate way to do this is to only send text information by email, asking the user to follow a link that you can track. Sort of:

 //lots of good info to identify yourself/company Thank you for your request... Please follow this link: http://somewhere/ for tracking information 

Unfortunately, this leaves in the hands of users a confirmation of your request. This is considered the most respectful way to do this.

If your application is not public (i.e. an internal application for your company), then the img src method already published is a good method.
