Send Email"" Button with custom text and fields

So just to explain further, Adreonna's solution will cause say Outlook or gmail to open up (what ever your default mail client is) and prefill the email for you to then manually send.

My posted solution will email from QuickBase.  Note also that you can set the "from" to come from the Last Modified by so the recipient can reply to your email.  To see that option you need to set the notification to trigger on single record changes only.
