I hate writing emails and I welcome services like this. The emails I sent are usually to higher-ups and need to be super polite, precise, and without errors, so they take a while to write. ChatGPT is excellent for this purpose. I give it a summary of the email I want and some info about the recipient. Its responses are largely spot on. I slightly edit them, run them through Grammarly and Language Tool and I am usually done in 1/5 of the time it would take me to write it myself. It is much less stressful too.
