Dear
Warm Greetings!
I wanted to take a moment to send a note of apology for missing our meeting scheduled for this past (Tuesday) at 11:00 AM.
This category of letters is for the purpose of providing “general” apology letters to help get started in the apology process. Usually, a letter may not be the best way to go, but a face-to-face meeting would be the prime way to express apology or deal with personal difficulties with others.
Refer to Matthew 18 for further guidance.
It is definitely a category you would not want to use verbatim but modify them according to your specific needs.
