There is nothing you can do. You may request a delivery or read receipt on the messages, but the receiver can block them.

i think, when i send a message is attached a link of website is named "deny or accept". if receiver select "deny" then this link will send again for us and then we could recognize it. but i couldn't do it. i want to have other way better than it.

That is the only way to do it. You cannot force people to respond to email messages, it is their choice.

right. if people don't click mail, it will notify that: that mail haven't read yet. if receiver click and get it into recycle or spam, it will notify so. also if receiver click to read mail, it will notify mail have read. i want to do so but i can not write code

There is no way to get these notifications unless the user sends you either a read receipt, or clicks some link that takes them to your website, which then sends a message to you. If you cannot write the code to handle this, then you should try a Google search to find some samples.

You can't in practice.
You can ask for a read receipt, but that request has to be honored by system which is reading the email, and some don't. Of those that do, most inform the user and ask for permission before responding.

The problem is that too many spammers used various ways to identify "live" email accounts and target them for future mailings. As a result the various ways have now been disabled one by one. Why did you think Outlook does not display images in emails by default? Because they can be used to track which messages have been opened, that's why...

Please check my answer - Track Email - Get Response when Email is Read[^]

You can follow this technique to know whether user has read your email or not.
But it's success rate is not 100%. Still you can try, if you like it.
