Formal vs Casual Ways to Say ‘I will check and get back to you’

When you need to tell someone you will look into something and reply later, the phrase “I will check and get back to you” works in many situations. But the exact words you choose can change how professional, friendly, or direct you sound. In formal settings—like a job interview or a client email—you want to sound reliable and respectful. In casual settings—like a text to a friend or a quick chat with a coworker—you can be shorter and more relaxed. This guide gives you the right phrases for both, with examples and notes so you can use them naturally.

Quick Answer: Which phrase should you use?

Use formal phrases when writing to a boss, client, professor, or someone you don’t know well. Use casual phrases with friends, close colleagues, or in informal group chats. Here is a simple breakdown:

• Formal: “I will investigate and follow up with you.”
• Casual: “Let me look into it and get back to you.”
• Neutral (works for most situations): “I will check and let you know.”

Formal phrases are best for professional emails, official messages, or any situation where you need to show competence and respect. They often use more precise verbs like “investigate,” “review,” or “confirm.”

• “I will investigate the matter and follow up with you.” – Use when the issue is serious or requires careful research.
• “I will review the details and provide an update.” – Good for checking documents, data, or project status.

Common mistakes

Even advanced learners sometimes choose the wrong tone. Here are mistakes to avoid:

Mistake 1: Using casual phrases in formal emails

Wrong: “I will check and let you know.” (in an email to a client)
Better: “I will review the details and provide an update.”

Mistake 2: Using formal phrases with friends

Wrong: “I will investigate the matter and revert to you.” (text to a friend)
Better: “Let me look into it and text you.”

Mistake 3: Overusing “circle back”

“Circle back” is fine in casual workplace talk, but it can sound like corporate jargon if used too often. Use it sparingly.

Mistake 4: Forgetting to give a time frame

Whether formal or casual, it helps to say when you will reply. Compare:
Vague: “I will get back to you.”
Clear: “I will get back to you by this afternoon.”

Better alternatives for specific contexts

Sometimes you need more than just formal or casual. Here are alternatives for specific situations:

For urgent matters

• Formal: “I will prioritize this and update you within the hour.”
• Casual: “I will check right now and let you know ASAP.”

When you need to ask someone else first

• Formal: “I will consult with the relevant team and revert.”
• Casual: “Let me ask my colleague and get back to you.”

When you are unsure about the answer

• Formal: “I will investigate further and provide a definitive answer.”
• Casual: “I am not sure, but I will look it up and tell you.”

Frequently asked questions

1. Can I use “I will get back to you” in formal writing?

Yes, but it is very neutral. For formal writing, it is better to add more detail, like “I will get back to you with the requested information by Friday.”

2. Is “revert” correct in American English?

“Revert” meaning “reply” is common in British, Indian, and other varieties of English. In American English, it is less common and can sound odd. Use “follow up” or “update” instead.

3. What is the most polite way to say this?

For maximum politeness, add “please” and a time frame. Example: “Please allow me to review the details, and I will provide an update by tomorrow.”

4. Can I use these phrases in a phone call?

Yes. In a phone call, casual phrases are usually better because they sound more natural. For example: “Let me check and call you back.”

Final tip

The best phrase depends on who you are talking to and the situation. When in doubt, start with a neutral phrase like “I will check and let you know.” Then adjust based on the relationship and formality level. Practice using both formal and casual versions so you can switch naturally when needed.
