Startup Idea : Email delaying service

I am on managerial position in one middle-sized company. I receive a lot of emails that I forward to my team members or even other managers to work on it. But sometimes I need them to focus on something more important at the moment than reading my emails and finding out how quickly they should reply. Would be great if I can just schedule the email to be sent one or two days later so I don't need to think about it any more and I am not disturbing my colleagues either. Best way would be to send it to specific email address that would automatically remove itself from the list of recipients before re-sending the message on scheduled time. I am sure there is many more opportunities to use such service.
