Here's an example of a letter using "Warmly" as a closing:
Dear Amy,

Your guidance and support have been instrumental in helping me navigate some important decisions in my life, and I cannot thank you enough for being there for me.
Your expertise and professionalism are truly admirable, and I am so fortunate to have crossed paths with you during this journey. You've provided me with a deeper understanding of the industry and the confidence to pursue my goals with renewed vigor.
As I wrap up this chapter of my life and embark on a new path, I want you to know that your positive influence will always stay with me. I sincerely hope that our connection continues, as it's been an absolute pleasure to get to know you and learn from you.
Warmest regards,
John Smith
