I don't know why it's happening can anybody tell me how I can resolve this issue

I dont see that actual email has been sent from your application. Did you setup devise confirmable model correctly? Also make sure that your mailer configuried properly. In order to recieve confirmation emails you need to set up :confirmable model to your user model. Here is the instructions on how to set up :confirmable model in devise gem: https://github.com/heartcombo/devise/wiki/How-To%3A-Add-%3Aconfirmable-to-Users
