Email apologies ready to go
When you have no time or inclination to craft a reply to an email, there is a website offering a list of canned responses. The site's description states: "At some point, we've all been in a situation where we didn't know what to say
or how to reply. Our website provides examples of canned responses for a variety of business situations." I particularly like the apology suggestions.
I'm sorry for what I said. I was wrong and I want to make things right.
I understand that you're upset, and I'm sorry for my part in this. Let's talk about how we can resolve this.
I can see that we're both upset. Maybe we can take a break and come back to this later.
