So your manuscript is perfect and you’re ready to query.
So you think, “Maybe I should order a dozen cookies to send with my query letter. That will definitely get [Insert Agent’s Name]’s attention!”
While getting your query letter some attention is the ultimate goal, and everyone likes cookies, we will need to file this under “Bad Idea”.
You don’t need to offer money or send baked goods or hire a singing telegram or do anything strange/weird. These gimmicks will just come off as awkward or creepy rather than fun.
Let your weapons be the usual ones — a good, strong query letter and a well-written manuscript (or nonfiction book proposal).
Gimmicks are never advised when sending a query. It’s just going to hurt your chances.
