Practice the text you actually write
Typing drills built from novels do not prepare you for an inbox. Emails and messages are full of names, dates, numbers, punctuation and polite phrasing, exactly the things people slow down on.
Punctuation and numbers count
Times, amounts, percentages and dates appear constantly at work and sit on keys most people practice least. A few minutes on the number row pays for itself quickly.
Clear writing, typed cleanly
Typing is only half of a good message. Vocabaura's writing tools help with word choice while typing practice handles the keyboard, so the sentence and the typing improve together.
Short bursts fit work better than long sessions. Five minutes before you start the day is enough to keep your accuracy steady, and it costs less attention than trying to improve while writing something that matters.
Typing is a useful, transferable skill, and it supports many computer-based roles, but it is one skill among many, and no particular speed guarantees any outcome at work.
