Expert writing Tips

Best practice

Use "I'll let you know as soon as" to set clear expectations for when someone will receive information, especially when dealing with uncertain timelines. This assures the recipient that they haven't been forgotten and creates goodwill.

Common error

Avoid using "I'll let you know as soon as" repeatedly without following through in a timely manner. If delays occur, provide updates to maintain trust and manage expectations. Instead of "I'll let you know as soon as I have any updates" try "I'll keep you posted".
