Be patient and follow-up

Almost everyone has become used to expecting responses to e-mails right away, so it can be frustrating to submit your music or send a note to a writer and get no response. Be patient. "The reviewers are usually completely swamped with submissions, so it will probably take a while before they get to your CD," says Georgevich. Give them two to three weeks before your first follow-up and then follow-up weekly after that. Remember to be polite, professional and patient."
