3. I Appreciate Your Telling Me

Whenever you use “I appreciate” instead of “thank you,” it’s seen as a more professional alternative. Therefore, “I appreciate your telling me” is a great option to use.

We would like to highlight that you have two options here:

  • I appreciate your telling me.
  • I appreciate you telling me.

Using “your” shows appreciation for the action. It’s a more formal way to thank someone for coming to you with information.

Using “you” shows your appreciation to the person. It’s a good way to sound a bit more friendly if that’s what you’re looking for.

That’s where “thanks for letting me know” comes in handy. It’s friendly and shows you appreciate the update.

It works best when emailing coworkers. It’s a really good way to show them how much you appreciate the information they’ve provided, especially if it helps to prepare you for something.

Warnings tend to help us prepare for what’s to come. Therefore, getting a warning in the workplace is a good way to ready yourself if you need to.

“Thank you for warning me” is a good alternative to “thanks for the heads-up.” It shows you really appreciate someone coming to you to warn you of something that might negatively affect you.

It works well when a client hears about some company changes relating to your job role. If they heard about it first, they might share it with you to let you know what’s coming.
