I sent out by snail-mail several query and synopsis letters around the middle of May. I haven't heard anything back from any of the agents. How long should I wait before I re query or send more out to other agents?
^^^^^^^^^How many queries did you send out? I recommend about ten at first, and wait to see at least one response. (You should hear something from one of them within about four months. Esp. if a lot of agents are on vacation, it can be a longer wait.) Then when a rejection or request for a partial comes in, send out another query to another agency, and so forth.
If you get all rejections or no responses, you might want to see if your query needs a little work.
While waiting, work on something else.
Okay so I rewrite the query and synopsis and resend. Do I resend to the seven agents or wait another month or two to do so. Thank you for all your advice.
If no response = no interest, then how is Kaylee supposed to know the query was even received? I know most of publishers get stacks of submissions, but I find this way of working just wrong. Sending back a SASE with a form rejection or a quick standard email takes time, but at least it means you act like a professional.
if they're responding with form rejections, your query isn't doing the job.
Sending Queries in the summer is usually a waste of time. Thats when agents take their vacations and even if they're in the office, not much happens because everyone else in the industry is on vacation. I'd wait a few weeks before bothering to send queries, they're only going to gather dust anyway.
Don't send your emails in rich text. Send them in plain text. That will strip them of any odd formatting issues that might come across weird.
