Another way to say “in case you are not aware” is “if you haven’t been informed.”

It’s great to use professionally, as it shows you don’t want to take someone’s knowledge for granted.

It suggests that you have a valuable update to share. However, it also suggests that you appreciate someone might have already heard the information from another party.

We recommend using it when emailing your boss. After all, it’s polite and respectful.

Therefore, it’s a great way to let your boss know you value them and their knowledge, and you don’t want to insult their understanding by assuming they don’t know something.

If you’re still unsure, check out this email example:

If you haven’t been informed, our client has pulled out of the deal. What do you think we should do moving forward?

Just in Case You Haven’t Heard (Informal)

You should try “just in case you haven’t heard” as another way to say “in case you are not aware.”

We’ve kept “in case” in the phrase because it’s already an effective way to check if the recipient knows something.

However, this time, you can use “haven’t heard.” It suggests that someone else might have updated the recipient before you.

We like this one when emailing a coworker. It shows you’re happy to update them, but you’d also understand it if someone shared the news before you could.

We also recommend reviewing this example:

Dear Julio,

Just in case you haven’t heard, they’ve decided to bring the presentation forward by a few days. Will that work for you?

All the best,

Is It Correct to Say “In Case You Are Not Aware”?

It is correct to say “in case you are not aware.” It’s polite to use it when updating someone about something they might already know about.

Also, it’s professional. So, it’s a good phrase to use in formal emails when you’re unsure whether someone might already have the information provided.

For example:

Dear Thomas,

In case you are not aware, they have moved the meeting to Tuesday. Will you still be able to attend?

All the best,
Dean Winters

As you can see, it’s a great way to update someone without taking their knowledge for granted.

It shows they might already know something, but you still want to update them just in case.

These extensions are also correct to use:

  • Just in case you are not aware
  • In case you are not aware yet

Including “just” or “yet” help to make the phrase slightly more informal and friendly. So, we recommend using the extensions above when contacting colleagues or people you like.

Finally, here’s a great variation to use:

  • If you were not aware

Honestly, it doesn’t change much about the original phrase. Instead, it switches “in case” for “if,” which is a more streamlined way to show that you’d like to update someone.
