Blending Leadership: Schedule Send

I'm finding myself more and more using the "schedule send" feature in Gmail to get things off my to do list when it is best for me, but to send the message on a date and/or at a time that might be better for the intended recipient. For example, I knew I was going to be off-site one day last week teaching a course at Columbia, but I wanted to send an email in advance of some other work happening that week. I could have sent it immediately after writing it (at like 5 am on a Monday), but instead scheduled for it to send at 9 am on a Tuesday.
