sammy said "I just assume everyone gets a notification whether it’s fb messenger, email or text so either way, no matter what time it is, it’s gonna be an alert if the person doesn’t have their volume off?
I send a message when I see the ad. I’m a night owl so I usually browse the classifieds and fb marketplace then. If I don’t send a message then, I’d forget by morning lol or I’d lose the contact info/ad "
Maybe I'm in minority but doubtful...I have all sound alerts for fb and emails turned off regardless if volume is on. Unfortunately my Samsung doesn't allow for just turning off sound for texts unless ringer is turned off as well. So I definitely am with OP that it is rude to send text messages thru the night time hours and would not like to be woken for frivolous things.
