Hi guy's! can anybody explain how i know that our send mail has been opened by receiver address. i am using PHP mailer in email marketing software. i am sending thousands of mail at a time. i want to trace all opening mail. please provide me information in detail's i have search a lot but nothing found helpful for me. Thank's for all of your effort in advance.
One of the most widely used methods is to include an image in the email and then you will be able to see how often that image has been downloaded by looking at the server logs. If you wanted tighter integration with your app you would have to call a script in your app that will record the IP etc and then serve up the image. There are problems with this though as lots of email clients don't show images by default when you first open an email.
Thank's for your reply. i am using this logic but some of the mail server disable image in that condition our logic is failed so if any guy's have another idea then please explain. best regard's with warm appreciation's
