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. However, the tone you choose—formal or casual—changes how professional, friendly, or direct you sound. In formal settings, such as client emails or official reports, you want to sound reliable and respectful. In casual settings, like chatting with a colleague or texting a friend, you can be more relaxed and brief. This guide gives you clear, ready-to-use phrases for both tones, explains when to use each, and helps you avoid common mistakes.

Quick Answer: Which Phrase Should You Use?

• Formal (emails, clients, managers): “I will investigate and follow up with you shortly.” or “I will look into this and update you by [time].”
• Casual (coworkers, friends, quick messages): “Let me check and get back to you.” or “I’ll find out and let you know.”
• Neutral (works for most situations): “I will check and get back to you.” (original phrase is already neutral and safe.)

Understanding Formal vs Casual Tone

The main difference between formal and casual versions is word choice and sentence structure. Formal phrases use precise verbs like “investigate,” “verify,” or “follow up,” and often include a specific time frame. Casual phrases use simpler verbs like “check,” “find out,” or “look,” and are shorter. Formal tone is best for official communication, while casual tone builds rapport in everyday conversation.
