If you’re getting so much email you can’t type five words, a button with wrong suggestions isn’t the solution either. Create your own text snippets with text expansion software and use those. They’ll always be correct and will truly save you time.
I do recommend this. Recently started making good use of one and its been a pretty cool change.
let me try a different tack - 99% of the value is in the affirmation of the response and the demnonstration of responsiveness, not the actual content value of the 5 words. you could send a thumbs up emoji, you could send a ".", just the "seen" and "acked" value is the value of that 5 word button
