What is your approach to ensuring clear async communication when you work opposite hours from your client?

Situation

In my previous remote assistant role, I supported a US-based marketing consultant who was online only during my nighttime. We had almost no real-time overlap, so all communication had to be asynchronous.

Task

I needed to create a system where the client would wake up to all necessary updates and context without needing to wait for a live chat with me.

Action

I set up a shared Trello board with a daily done column where I moved all completed tasks with brief notes and links to deliverables. I also wrote a daily wrap-up email sent at the end of my shift summarizing what was accomplished, any pending items requiring the client's input, and my next day priorities. I used Slack for urgent flags, but always prefaced messages with 'Non-urgent, for review when you're online' to respect their time.

Result

The client told me the daily wrap-up email became their favorite part of the morning because it gave them full visibility without needing to dig through messages. We reduced the need for catch-up calls by 80%.
