Generally, it works well when emailing your employer. It’s respectful and polite, which is best when you’re trying to get your boss’s attention.

Usually, this is a helpful way to share information without assuming anything.

4. Have You Heard

Another way to say “did you know” is “have you heard.” This time, we want to steer away from email contexts to show you how to use it in text messages.

Feel free to use this when messaging a coworker. It shows you’re chatting with them outside of the workplace and would like to know whether they’ve received an update.

This translates well into texts. It allows you to discuss work-related issues outside of the workplace when they’re relevant.

Also, it helps that the phrase is formal and polite. So, it goes a long way when you’re still trying to keep things formal, even in a text.

We recommend using this when texting friends. It’s a useful way to sound more conversational and polite when asking about information.

Again, it suggests that you don’t want to assume someone doesn’t already know something. So, you can start a question like this to find out whether you need to explain something further.

Going back to something a little more professional, you can use “were you made aware.”

This works best at the start of a business email. It shows that you’re trying to figure out whether someone is already aware of the information you need to share with them.

For instance, you can use this when writing to a client.

It lets them know you’re keeping them in the loop, but you’re unsure whether they’ve already been told about an update. Perhaps someone else in your company got to them first.

So, you can check out this email example to learn how it works:

You might need to catch them outside of the workplace. Sometimes, you’ll hear information when you’re not in the office, so an email is out of the question.

If you can’t email, you can instead use this in a text. It shows you’re sharing information that you’ve heard. It also implies that you are unsure whether your boss already knows about it.

Overall, the phrase is formal and sincere. So, your boss will be happy to receive a text like this.
