Yes -- "chime in" is natural and common in informal asynchronous channels like Slack, Teams, and conversational internal email, especially for a short confirmation, added context, or a suggestion. It's less natural in a highly formal or legalistic written record.
The written, asynchronous cousin of the meeting sense
This use covers the written cousin of the spoken meeting sense: adding a brief comment to a thread rather than an in-person conversation. "Just chiming in to confirm..." is a common, natural opener for exactly this kind of message.
"Just chiming in to confirm the deploy went out clean overnight." -- Slack, a brief confirmation
"Chiming in here to add the client's timezone before we lock the call time." -- an internal email thread, added context
Register still matters here, though. A casual chat comment shouldn't be read as completing a step that actually requires a documented, formal approval or sign-off. Treating a Slack message that says "chiming in to say this looks good" as if it were the documented sign-off a formal change process actually requires is a real overreach -- the tone is casual, but the process behind it isn't.

A peer Slack thread or an internal status update is a good fit for this use. A compliance record or a formal external letter is not. The distinction isn't about how important the content is -- it's about whether the channel itself is built to carry a required, documented step.
The mistake: treating a chat comment as a formal record
The mistake is using an informal chat contribution as if it satisfied a requirement that needs a formal record. A quick "chiming in" in Slack is a fine way to confirm or add context. It is not the same thing as a required written approval, and treating it that way can leave a real gap in a process that actually needed a paper trail.
Practice scenarios
Practice using chime in in situations like:
- adding a brief confirmation or piece of context to a Slack or Teams thread
- opening an async message naturally with "just chiming in to..."
- recognizing when a thread comment isn't enough and a formal record is actually required
Useful practice phrases:
- "Just chiming in to confirm..."
- "Chiming in here to add..."
- "This is a quick note, not a formal sign-off -- we'll still need..."
A thread comment travels fast and costs little.
A formal record still has to exist somewhere else.
