The phrase “as you know” is common in everyday and professional communication, but it can sometimes sound repetitive, blunt, or even slightly presumptuous. Choosing the right formal synonyms for “as you know” can make your emails, reports, workplace conversations, and client messages sound more polished.
A good professional way to say “as you know” depends on your relationship with the reader and how certain you are that they already know the information. In a business email, for example, “as previously discussed” may sound more precise, while “as you may be aware” offers a softer and more diplomatic tone.
This guide explains the best formal alternatives to “as you know,” including professional, friendly, workplace, client-facing, and email-ready options.
What Does “As You Know” Mean?
“As you know” means that the speaker believes the listener already has knowledge of the information being mentioned.
Simple meaning
“As you know, our project deadline is Friday.”
This means:
“You already know that our project deadline is Friday.”
The phrase often reminds someone of information that you believe they already understand.
Tone of “As You Know”
The phrase can sound:
- Professional
- Neutral
- Direct
- Familiar
- Sometimes presumptuous
The tone depends heavily on context.
For example:
“As you know, we need your approval before Friday.”
This can sound somewhat forceful.
A softer alternative would be:
“As you may be aware, we need your approval before Friday.”
Why Look for an Alternative?
People often search for a synonym for “as you know” because they want to:
- Sound more professional
- Avoid repetition
- Use more formal language
- Avoid assuming what the reader knows
- Make an email sound more diplomatic
- Improve workplace communication
- Communicate with clients more tactfully
When Should You Use “As You Know”?
The phrase works well when you have strong reason to believe the recipient already knows the information.
1. In Emails
You can use it when referring to a previous conversation or established fact.
Example:
As you know, the team will begin testing the new system next week.
However, business email phrases such as “as previously discussed” may provide more specific context.
2. In the Workplace
It can work when communicating with colleagues who share the same information.
As you know, our department has moved to a new reporting system.
For formal workplace communication, avoid using it too frequently.
3. With Clients
Use caution with customers and clients. You may not want to assume they remember something.
Instead of:
As you know, your contract expires next month.
Consider:
As previously discussed, your contract expires next month.
Or:
As you may recall, your contract expires next month.
These options sound more diplomatic.
4. In Networking
A softer expression often works better because you may not know how familiar the other person is with the topic.
As you may be aware, our industry has seen significant changes this year.
5. In Customer Service
Avoid language that could sound like you are blaming the customer for not knowing something.
Instead of:
As you know, our policy does not allow refunds after 30 days.
Try:
For reference, our refund policy allows returns within 30 days.
This approach supports good email etiquette and professional communication.

Email Examples Using Formal Alternatives
1. Email to a Client
Instead of:
As you know, we are launching the new service next month.
Use:
As you may be aware, we are launching the new service next month.
This sounds more diplomatic because it does not assume the client has received every update.
2. Email to a Manager
As previously discussed, I have completed the revised project timeline. Please let me know if you would like me to make any further changes.
This works well because it connects the current message to an earlier conversation.
3. Email to a Colleague
As we discussed, I’ll prepare the presentation before tomorrow’s meeting.
This sounds natural and collaborative.
4. Email to a Customer
Instead of:
As you know, our return policy is 30 days.
Use:
For reference, our return policy allows customers to request a return within 30 days of purchase.
This removes the assumption that the customer already knows the policy.
5. Networking Email
As you may recall, we met at the technology conference last year. I enjoyed our conversation about emerging trends in the industry.
“As you may recall” works particularly well when reconnecting with someone.
6. Meeting Follow-Up
As discussed during our meeting, the team will complete the first stage of testing by Friday.
This creates a clear written record of the discussion.
Common Mistakes When Using “As You Know”
1. Assuming the Reader Knows
The biggest problem occurs when you state something as known when the recipient may not actually know it.
Less effective:
As you know, the supplier changed its pricing.
Better:
The supplier recently changed its pricing.
Or:
You may have seen the supplier’s recent pricing update.
2. Using It Too Often
Repeating “as you know” throughout an email can make your writing sound mechanical.
Instead, vary your language:
- As previously discussed
- As mentioned
- As you may recall
- As outlined earlier
- As noted previously
3. Sounding Condescending
Sometimes “as you know” can imply:
“You should already know this.”
That implication can create tension.
Instead of:
As you know, you were required to submit the form.
Try:
As previously communicated, the form was due on Friday.
The second version focuses on the communication rather than the person’s knowledge.
4. Choosing an Overly Formal Expression
Formal does not always mean better.
For a colleague, this may sound unnecessarily stiff:
As outlined in our earlier correspondence…
A simpler option works better:
As we discussed…
Good professional communication matches formality to the situation.
5. Using “As You Are Aware” Without Confidence
“As you are aware” strongly assumes the reader knows the information.
If you are uncertain, use:
As you may be aware…
That small change makes the statement more diplomatic.

Cultural Usage: US vs. UK English
US English
American business communication often favors concise, direct language.
Common choices include:
- As discussed
- As mentioned
- As you may be aware
- As previously discussed
- As we agreed
For everyday workplace emails, shorter phrases often feel more natural.
Example:
As discussed, I’ll send the proposal by Friday.
UK English
British professional communication may use slightly more formal or diplomatic wording, particularly in traditional corporate settings.
Examples include:
As you may be aware…
As previously noted…
As outlined in our earlier correspondence…
However, modern UK business writing also favors clear and concise language. Formality should never replace clarity.
Corporate Communication
Corporate environments often require neutral language that avoids personal assumptions.
Instead of:
As you know, the company changed the policy.
Consider:
As previously communicated, the company has updated the policy.
This sounds more objective.
Customer Service
Customer-facing communication should avoid implying that customers failed to understand something.
Instead of:
As you know, our terms do not allow refunds.
Try:
For reference, our terms allow refunds within 30 days.
The second option sounds more helpful and less confrontational.
Networking
Networking communication benefits from warmth.
Instead of:
As you know, I work in marketing.
Try:
As you may recall, we spoke about my work in marketing when we met at the conference.
This creates a more personal connection.
