Before you send out any manuscript, make sure to take the time to look over that manuscript one more time for any silly little mistakes. We won't kill you for the small stuff but like Hallmark says, "when you care enough to send the very best." That statement is so true.
Common things I have seen coming in submissions?
- Writers have used the "review function" but forgot to take out the notes to themself for later research.
- Page numbers messed up
- Missing the basics in the cover letter (i.e. the title, word count or genre)
- Do you have an accurate email?
- People have forgotten to insert the material in an e-query.
Sure these are small, but you don't want to mess with small stumbles like this when you have a one shot deal.
