How do I respond to this email from my boss?

Apologies for the many posts on this but I’m new to the corporate world and I don’t know the best way to respond. I made the posts about making mistakes and having to be shadowed, bombing my meeting and how I said I felt overwhelmed/had personal issues. My boss sent me a recap email and listed out what my expectations are. She CC’d my supervisor. Just just for context she also notified me today they are transferring one of my two biggest clients to someone else.

I planned to send an email tomorrow as a response to the recap and thank her for meeting with me, say how much I love the job and the company and I am committed to improving.

What would you say?
