Best when you are going to do something and will report the outcome afterward. Example: I’ll let you know how it goes after the meeting.
I’ll keep you informed
More formal and suitable for professional or official communication. Example: I’ll keep you informed of any changes to the timetable.
I’ll share any updates
Neutral and concise when you do not yet know when new information will arrive. Example: I’ll share any updates as they become available.
I’ll let you know if anything changes
Specific and reassuring when the current plan is stable unless circumstances change. Example: I’ll let you know if anything changes before Friday.
I’ll update you as things progress
Useful for ongoing work, applications, projects, or cases with several stages. Example: I’ll update you as things progress with the review.
I’ll keep you in the loop
Conversational workplace wording that emphasizes continued inclusion. Example: I’ll keep you in the loop on the discussions with the supplier.
I’ll send you an update when I know more
Sets a sensible expectation when you are waiting for further information. Example: I’ll send you an update when I know more about the start date.
I’ll follow up with any developments
Professional and useful when developments may require another message. Example: I’ll follow up with any developments after the committee meets.
I’ll make sure you’re kept informed
Reassuring wording when responsibility for communication matters. Example: I’ll make sure you’re kept informed throughout the process.

Set a Useful Expectation
If possible, say what will trigger the next update. “I’ll send you an update when I hear from the supplier” is more informative than an open-ended promise to keep someone updated.
For frequent project communication, “I’ll keep you in the loop” is natural but informal. In formal correspondence, “I’ll keep you informed” or “I’ll follow up with any developments” is safer.
