She logs in remotely on my email. To get her up to speed she watched what and how I replied to things for about a week, until I had her start drafting emails as replies that I would approve (or edit) and reply. After a while she just got it. She's based in the Philippines and works from 11p - 3a her local time. I proactively schedule my conflicts and times in my calendar, and then she can schedule anything in the open space.
I could just not answer for a few hours a day, but I have alot of people who expect a quick response. This solves that and gives me back my evenings to spend with the family.
