Here is one way to use Notification emails.
1. Make a new form, call it the Survey form and customize it with the fields you want.
2. Make a new checkbox field, call it Survey Sent
3. Make a new email Notification, when a ticket is modified and the additional criteria can be when a specific field Survey Sent changes AND Survey Sent is equal to Checked. Choose the Survey form to send with the notification and customize the email.
4. Make a new formula url button, this can be placed on the form which will mark the checkbox and trigger the notification
URLRoot() & "db/" & Dbid() & "?a=API_EditRecord" &
"&rid=" & [Record ID#] &
"&_fid_305=1" &
"&rdr=" &
URLEncode(URLRoot() & "db/" & Dbid() &
"?a=dr&rid=" & [Record ID#])
*replace fid_305 with your new checkbox fid
