Ask HN: Is direct mail dead?

Good folks of hacker news! I'm building a web app around mailing letters as easily as sending an email to as many people as you would like.

So naturally, I'm curious what the general sentiment about direct mail is... So how do you guys feel about it? When was the last time you mailed a letter? Do you hate mailing letters?

All of this started because I hate mailing letters and I figured other people were just like me... So tell me if I'm wrong! Thanks!
