“Just to let you know” introduces information the other person should be aware of. Depending on tone, you can use “for your information,” “I wanted to let you know,” “a quick heads-up,” or simply state the information directly.

I wanted to let you know
A natural, slightly warmer alternative for personal or professional updates.
Example: I wanted to let you know that the report has now been submitted.
Just so you know
Informal and conversational, best with people you already know well.
Example: Just so you know, I’ll be offline after 3 p.m.
For your information
Neutral to formal, though it can sound blunt if used unnecessarily.
Example: For your information, the policy was updated on Monday.
For your awareness
Professional wording for information the recipient should know but may not need to act on.
Example: For your awareness, the building will be closed on Friday.
A quick heads-up
Friendly and informal, especially for advance notice about something that may affect the person.
Example: A quick heads-up: the train is running about 20 minutes late.
I thought you should know
Useful when the information seems important or personally relevant.
Example: I thought you should know that your name came up in the discussion.
I wanted to keep you informed
Suitable for ongoing updates where the recipient expects to be kept in the loop.
Example: I wanted to keep you informed that the review is still in progress.
I’m writing to let you know
A straightforward formal email opener for notices and updates.
Example: I’m writing to let you know that your application has been approved.
Please note that
Concise and useful when drawing attention to an important detail or instruction.
Example: Please note that the office will open at 10 a.m. tomorrow.
Just a note to say
Friendly and light, especially for brief personal or informal professional messages.
Example: Just a note to say that the parcel arrived safely.
I wanted to update you
Best when the information represents progress or a change since the last contact.
Example: I wanted to update you on the recruitment timeline.
Here’s a quick update
Direct and useful when the message contains new status information.
Example: Here’s a quick update: testing is complete and the site is live.
I wanted to make you aware
More formal and often suitable for issues, risks, or changes the recipient should notice.
Example: I wanted to make you aware of a possible delay to delivery.
Sometimes You Can Skip the Lead-In
If the information is simple, the clearest message may be to state it directly. Instead of “Just to let you know, the meeting is cancelled,” write “The meeting has been cancelled.”
Use a lead-in when it helps signal tone, importance, or the reason for the update—not simply out of habit.
