Email Etiquette

I sent some emails out last week and got no reply. Nothing.

There is a difficult etiquette issue here. Do I assume that the message has not got through? Do I assume that the person who received it does not think the message worthy of reply or would rather not talk to me?

This is tricky. If I send a further message saying "Did you get my email?" I force them into responding when they'd probably rather not. If I do nothing, and the mail didn't get through, then they might think me rude for not getting in touch, or I miss out on a conversation which may benefit both of us.

In the end I solved the problem by checking my junk email folder. Which of course is where the responses had ended up. I'm no further forward on the etiquette issue, but I'm going to check through my junk email more frequently....
