When you need to tell someone that something cannot wait, the phrase “this is urgent” works, but it can sound too blunt in a professional email or too stiff in a quick message to a colleague. The right choice depends on who you are talking to and the situation. In formal settings, you want to show respect and clarity without sounding demanding. In casual settings, you can be direct and friendly. This guide gives you the exact phrases to use for each situation, with examples and common mistakes to avoid.
Quick Answer: Which Phrase Should You Use?
Use formal phrases when writing to a boss, a client, or someone you do not know well. Use casual phrases with coworkers you know well, friends, or in quick chat messages. Here is a simple guide:
- Formal: “This matter requires immediate attention.”
- Casual: “This can’t wait.”
- Neutral (works in most situations): “This is time-sensitive.”
Formal Ways to Say ‘This is urgent’
Formal language is best for emails to senior management, official requests, or communication with external partners. The goal is to communicate urgency without sounding panicked or rude.
Common Formal Phrases
| Phrase | When to use it |
|---|---|
| This matter requires immediate attention. | Use in official emails or written requests. It is polite and clear. |
| Your prompt response would be appreciated. | Good for ending an email when you need a quick reply. It is respectful. |
| This is a time-sensitive issue. | Works well in professional emails. It explains why you need fast action. |
| I would be grateful for your urgent assistance. | Use when you need help from someone. It combines politeness with urgency. |
| Please prioritize this request. | Direct but still professional. Use when you need something moved to the top of a to-do list. |
Natural Examples (Formal)
Email to a client:
“Dear Ms. Chen,
This matter requires immediate attention. The contract deadline has been moved forward, and we need your approval by end of day. Your prompt response would be appreciated.
Best regards,
James”
Email to a manager:
“Hi Sarah,
This is a time-sensitive issue regarding the quarterly report. I would be grateful for your urgent assistance in reviewing the attached figures.
Thanks,
Tom”
Common Mistakes (Formal)
- Mistake: Using “urgent” in the subject line and then writing a long, relaxed email. Fix: Keep the tone consistent. If the subject says “URGENT,” the body should match that urgency.
- Mistake: Saying “I need this now” in a formal email. Fix: Use “I would appreciate your prompt attention to this matter.”
- Mistake: Overusing “urgent” in every email. Fix: Save formal urgency phrases for truly important matters. Overuse makes people ignore your requests.
Casual Ways to Say ‘This is urgent’
Casual language is for instant messages, quick emails to teammates, or conversations with people you work with daily. The tone is friendly but still clear.
Common Casual Phrases
| Phrase | When to use it |
|---|---|
| This can’t wait. | Use in chat or quick emails. Very direct and clear. |
| I need this ASAP. | Common in workplace chat. Short and understood by everyone. |
| Can you take a look at this right away? | Polite but casual. Good for asking a coworker for help. |
| This is kind of urgent. | Softens the urgency. Use when something is important but not critical. |
| Heads up, this is time-sensitive. | Friendly warning. Works well in team chats. |
Natural Examples (Casual)
Slack message to a coworker:
“Hey Mike, this can’t wait. The client just changed the deadline to tomorrow. Can you take a look at this right away?”
Quick email to a teammate:
“Hi Jen,
Heads up, this is time-sensitive. I need the updated file ASAP. Thanks!
Alex”
Common Mistakes (Casual)
- Mistake: Using “ASAP” in every message. Fix: Use it only when you truly need something fast. Otherwise, it loses meaning.
- Mistake: Being too casual with someone you do not know well. Fix: If you are unsure, start with a neutral phrase like “This is time-sensitive.”
- Mistake: Writing “URGENT” in all caps in a casual chat. Fix: Use lowercase and a friendly tone: “this is urgent, can you help?”

FAQ: Common Questions About Saying ‘This is urgent’
1. Can I use “urgent” in the subject line of an email?
Yes, but use it sparingly. If you mark every email as urgent, people will stop taking it seriously. Reserve it for truly time-sensitive matters. A better approach is to use “Time-sensitive” or “Action needed by [date].”
2. Is it rude to say “this is urgent” in a casual message?
Not if you know the person well. With close coworkers, “this is urgent” or “this can’t wait” is fine. With someone you do not know well, it can sound demanding. Use a softer phrase like “Can you help with this? It’s time-sensitive.”
3. What is the most polite way to say something is urgent?
The most polite way is to explain why it is urgent and then make a request. For example: “I apologize for the short notice, but the client has moved the deadline. I would appreciate your help with this as soon as possible.” This shows respect and gives context.
4. How do I say something is urgent without sounding panicked?
Use calm, clear language. Instead of “This is extremely urgent, please help now!” try “This requires attention today. Could you review it when you have a moment?” The word “attention” sounds professional, while “urgent” can sound emotional.
