How about saving to draft? Reading the next day & then deciding.
I started doing that for work just to check spelling, grammar, complete thoughts. Was surprised how the next day that email was either a brilliant analysis of a situation (rare!!) or not even understandable to me!!!!! Then you have the option of delete, send or print. Re T stuff, I was able to pear down all the words and see the issue. My T doesn't like emails. He wants to 'see' the words. But writing something out when it happens, is definitely helpful.
