Service Entity Question regarding emails sent to client

Hello,

I was wondering if the following is possible:

I currently have a workflow that when a case is resolved, it sends out an email to the client.

In the email I would like to add something like the following:

Your incident INC00001 has been resolved and will automatically close in 24 hours. If you feel the issue is not resolved, please click the following link to reopen your incident:

Click here if your issue was not properly resolved. INC00001

Is it possible to have the client reply/click a link to re-open the case in CRM and alert someone that the case has been re-opened?
