I use emojis at times, sometimes it makes the entire difference between how someone will understand a gesture. Some people will see them differently than I do though, there's a bit of cultural diversity in how one understands emojis.
Like:
Maybe you should instead do this - [neutral, no emotion]
Maybe you should instead do this :/ - [disapproval, uncertainty]
Maybe you should instead do this :) - [genuine, happy input]
Maybe you should instead do this :P - [happy, silly, joking]
Maybe you should instead do this ;) - [arrogant, smartass]
Maybe you should instead do this :( - [unhappy, empathic]
It changes so much if not overused, it guides how a sentence is read, there's nothing wrong with adding a bit of flair.
But if someone starts using emojis in place of actual words, I won't even try, I am not into deciphering hieroglyphics!
You do you.
