This email address thing is making me nutso!
First, I pull all my email into an inbox on my computer with a mail management program called Entourage. If your email arrives in my Entourage in box, I read it. I don't inspect every email address to make sure it's not spam. Entourage does that for me.
The inspection happens when I log on to gmail directly at the website and look at those emails left in the spam folder. That's Priscilla's domain. That's when I inspect email addresses and try not to open email that's sent by someone who's email name doesn't seem to match their email address.
The reason I bring this up is not to add a new rule, or a new hurdle. It's to illuminate that if you do NOT hear back, it may be that your email didn't survive Priscilla.
Honest to helvetica I'm not trying to make your life or the query process more difficult.
I'm simply trying to tell you what happens on THIS side of the query process so you can avoid the Desert of No Response (particularly from those of us who do respond to every email query)
