How to send an email that links back to a created node?

Hi, I've created a rule that sends an email to a specific role when a user creates a node of a specific content type. My problem is that on the email, I want the [node:nid] to be clickable and goes to the created node when the recipient of the email clicks on it. How can I achieve this?

Example:
I tried to put on message:
A user has posted a question on [node:nid].

Email of the site:
A user has posted a question on 49.

Thanks.
