How to approve sharepoint workflow directly from email

Hi,

Created sharepoint designer approval workflow. In email task notification body provided Approve and Reject options.

For "Approve" text provided [%Task:URL%] link. When i click on Approve link in the mail it's redirecting to task item and there i have to approve.

But i want to reduce extra action, directly from mail i want to approve that task or reject the task.

Please help me, how to provide the link in mail

Thanking You, Nagendra.
