Sorta unrelated, but I found myself saying “sorry about that” as a courtesy in work related emails. Like, “oh sorry about that, seems there’s been a miscommunication and…”

I started rephrasing it to thank you. Like “Oh thanks for catching that! Much appreciated”

It’s a really small thing, but a “sorry” sorta puts the onus on the person to give you forgiveness. A “thanks” shows that you appreciate the effort they put it.

Giving a legitimate thank you every now and then to someone, more than just “thanks”, can actually have a huge effect
