Thanks for letting me know
The most useful all-purpose alternative when someone has provided relevant information. Example: Thanks for letting me know about the change.
That’s helpful to know
Shows that the information is practically useful to you. Example: That’s helpful to know before we finalize the schedule.
That’s useful to know
Very similar to “helpful to know,” with a slightly more matter-of-fact tone. Example: That’s useful to know for next time.
I appreciate the update
Professional and polite when the information is a new development or status update. Example: I appreciate the update on the timeline.
That’s good information to have
Natural when the information may be useful later, even if no immediate action is needed. Example: That’s good information to have before we make a decision.
I’m glad you mentioned that
Best when the information corrects an assumption or reminds you of something important. Example: I’m glad you mentioned that—I had forgotten about the deadline.
Thanks, that clarifies things
Best when the new information resolves confusion or makes a point clearer. Example: Thanks, that clarifies things—I understand the process now.
Understood, thanks
Concise and professional when you mainly need to acknowledge the information. Example: Understood, thanks. I’ll update the document.
That’s interesting
Use when the information is genuinely interesting, but not necessarily useful or actionable. Example: That’s interesting—I didn’t realize the policy had changed.
I’ll keep that in mind
Best when the information should influence a future decision or action. Example: I’ll keep that in mind when I speak to them.
