Dear Miss Snark,
My limited experience with agents tells me that they are pretty quick in rejecting a ms that doesn't appeal to them. Of the three agents who asked for my full ms, two sent rejection letters within a week. The third agent - veteran, reputed etc - has not uttered a squeak for over two months now. She hasn't even responded to my mail enquring about the status of her evaluation. I know of cases where she has sent rejection letters within 10 days time, so how do I interpret her silence?
Two months on a full and you're pestering her already?
You're LUCKY to have an arm left. I'd have snapped it off with the Jaws of Snark...right before I sent you briskly on your way out the door.
In case this is news to you: reading full manuscripts can take a while. Minimum 90 days is industry standard. Lots longer is normal. It doesn't mean anything. Quit trying to parse out meaning from this.
If you want to know what happened your email, she deleted it.
She has learned, as I have, that people who pester you about submissions have a tendency to keep writing back if you send them updates. I tell people how long it will be and don't give updates before that. If you email me, I delete it. Being "nice" to you is counterproductive.
I get 150 emails a day that are for projects I currently represent or am dealing with. I get another 25 or so from people like you. Today I got an email from some nitwit alerting me to the fact he was sending a query letter. I got another one from someone looking for an email address for an agent I'd recommended. I got another one telling me a novel was almost finished--a novel I'd never heard of.
Delete. Delete. Delete.
Sit down, quit emailing her, and query other agents.
