Apology Letter For Sending Too Many Texts
Dear {Recipient},
Please accept my apologies for sending too many texts {yesterday/the other day/etc.}. You were right, I was being inconsiderate and bothersome. I should have been more patient and waited for you to reply, especially when the matter at hand was not urgent.
I promise to be more respectful of other people's time and boundaries going forward. I won't bombard you with unnecessary texts again.
Sincerely,
{Your Name}
