LONG Email Notifications and Templates

Hello,

Will you please confirm the exact triggers for the following emails templates:

Schedule Phone Screen
Email sent to interviewer for an Interview
Invite Candidate
Send Offer Letter
Initiate Offer Approval
Candidate not shortlisted
Interview evaluation submitted
Candidate response on offer letter
Job Position Closed
Cancellation of interview scheduled
Interview evaluation pending
Interview Acceptance Status: Pending

Is there any way to edit any of these templates prior to it being sent to a candidate by the Admin?

Can you please provide a list of the items that can be inserted into each emails to customize using the brackets? For example: [candidatename], [candidateemail]

Is it possible to add custom email templates and triggers into a specific client's account (without affecting any other accounts)?

Thank you,
Veronica
