Currently, to approve any salesforce record through email, you have to reply to approval email using Approved/Yes and it gets approve.

I just want to skip the step of writing "Approved/Yes" for approving records. Instead of this, I would like to create a HTML template and provide some button or link into that. When user will click the button or link, then it should approve that salesforce record ( make sure that button or link doesn't open a new salesforce window).

I don't know whether it's achievable or not, but I would like some positive response for this problem. Can anyone please suggest something ?
