First Reply Time & Using Automation to Acknowledge Tickets

Hello,

I am currently using trigger to automatically send an email to the requester of a newly submitted ticket to acknowledge that the ticket has been received.

My question is that would the trigger reflect on reporting that we've met the First Reply Time SLA?

This question also stems from another situation where my service desk team is trying to improve their one-touch ticket metrics as well.  If the agent has to use 1 reply to acknowledge the ticket and then reply again to advise the requester that the issue has been resolved, would the ticket no longer be considered as one-touch?

Thank you
