Email Templates - Link to Record

Is there a way if I create a email template (for eg. template is sent to the owner of a new Contact) is there a way I can make it link back to the said record.

So, Joe received a email stating

Hi Joe

A new contact - ${Contacts.First Name} ${Contacts.Last Name} - has been created. Can you please follow up within 7 days.

I would like ${Contacts.First Name} ${Contacts.Last Name} to be a link to the contact record. Is this possible?

Also, if you open the email on your iphone, is there a way for it to open via the app rather than in a browser?

Thanks
