Follow up emails are pegged to an event, like product purchase or subscription renewal, which occurs at a specified hour of the day. If a subscription expires at 11:30 p.m. or 1:00 a.m., that's when the follow up email is sent. It's unprofessional at best. There needs to be an option that allows emailing at a specified time of day, say 11:00 a.m., or a specified period, like 10:00 a.m. to 5:00 p.m.

Virtually the same request was made previously and is marked "Completed" but I am told that it was never done. http://ideas.woocommerce.com/forums/133476-woocommerce/suggestions/16040521-have-option-to-send-follow-up-emails-at-chosen-tim
