Is late night emailing now rude due to nightstand smartphones bleating?

[Johann Jells]

I was just about to hit send on a group email announcing an open house when I remembered my wife commenting that people now sleep with their smartphones on the bedstand and an late email alert is like a late night call, rude. Is this true, or am I an ignorant old luddite and most people are clever enough mute their email alert at night? Given that most people couldn't set their VCR clock back in the day, I'm hesitant to make assumptions. The no landline, hyperconnected trend is changing many patterns, and it's hard to keep up.

I have a great plugin called boomerang, that's let's me schedule an email I'm writing now to be sent later.

I don't like sending emails at 2am for certain purposes because they get buried behind 8 hours of spam until seine checks their email.

Also some people ask me why I'm up at 4am lol.

Better just to queue until 9 am or so the next morning.
