I agree with @CharlieStarDust I think it depends what is in the email and if there are time constraints in the email. Like for example if it were an email to see if she has any scheduled openings this week, and today is Tuesday, you might want to send a follow up by the end of today, or call the office, because there are only three days left in the week. Email conversations tend to be slow. I would think more time rather than less time. HUGS Kit
