Email is good.

Wes Kao:

Before you hit “send,” delete these words from your writing. Your message will be stronger for it.

• fine — “Saying fine sounds like you’re not fine.”
• however — “However” is a melodramatic way to say “but.”
• unfortunately — “Don’t make things sound worse than they actually are.”

I once had my own list but it was focused on educational writing, less-so emails.
