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 respond later, the phrase “I will check and get back to you” works in many situations. However, the right version depends on who you are talking to and the setting. In formal contexts, such as writing to a client or a senior manager, you want to sound reliable and professional. In casual settings, like chatting with a coworker or a friend, a shorter, friendlier phrase feels more natural. This guide gives you direct alternatives for both formal and casual situations, with clear examples and explanations so you can choose the best option every time.

Quick Answer: Formal vs Casual at a Glance

If you need a fast answer, here is the simplest breakdown. Use a formal phrase when you want to show professionalism, respect, or when the matter is serious. Use a casual phrase when the tone is relaxed, the relationship is close, or the topic is low-stakes.

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

Understanding the Context: When to Use Formal vs Casual

The choice between formal and casual language depends on three main factors: your relationship with the person, the setting, and the importance of the topic. In a professional email to a new client, formal language builds trust. In a quick message to a teammate you know well, casual language feels natural and efficient. Getting this right helps you communicate clearly and avoid sounding too stiff or too informal.

Formal Situations

Use formal alternatives when you are writing to someone you do not know well, such as a client, a senior executive, or a government official. Also use formal language in official documents, job applications, or any situation where you need to show respect and competence. Formal phrases often include words like “investigate,” “verify,” “follow up,” and “provide an update.”

Casual Situations

Use casual alternatives when you are speaking or writing to colleagues you work with daily, friends, or family members. Casual language is also fine in internal team chats, quick phone calls, or informal emails where the tone is friendly. Casual phrases often use shorter words like “look into,” “check,” “let you know,” or “circle back.”

Natural Examples in Context

Seeing these phrases in real situations helps you understand how to use them naturally. Below are examples for both formal and casual settings.

Formal Examples

Email to a client: “Thank you for your inquiry. I will investigate the matter and follow up with you by the end of the business day.”

Response to a manager: “I will verify the data with the team and provide an update before the meeting.”

Written report: “I will review the submitted documents and respond accordingly once the analysis is complete.”

Casual Examples

Message to a coworker: “Sure, let me look into it and get back to you in a bit.”

Phone call with a friend: “I am not sure right now, but I will check and let you know later.”

Team chat: “I will take a look and get back to you after lunch.”

Common Mistakes to Avoid

Even advanced learners sometimes make small errors when using these phrases. Here are the most common mistakes and how to fix them.

Mistake 1: Mixing Formal and Casual Language

Using a very formal word in a casual sentence can sound awkward. For example, saying “I will investigate and get back to you” to a close friend feels too serious. Instead, use “I will look into it and get back to you.”

Mistake 2: Being Too Vague

If you only say “I will get back to you” without mentioning what you will check, the other person may feel unsure. Always add a short explanation. For example: “I will check the schedule and get back to you.”

Mistake 3: Forgetting to Set Expectations

In formal settings, it helps to say when you will respond. Saying “I will follow up shortly” is better than “I will get back to you” alone. In casual settings, you can be less specific, but a time frame like “in a few minutes” is still helpful.

Mistake 4: Using “Revert” Incorrectly

Some learners use “revert” to mean “reply,” but this is not common in American English. In professional writing, “revert” usually means to return to a previous state. It is safer to use “respond” or “follow up.”

Better Alternatives and When to Use Them

Here are some of the most useful alternatives for “I will check and get back to you,” organized by tone. Each alternative includes a note on when it works best.

Formal Alternatives

• “I will investigate and follow up with you shortly.” Use this when the issue is complex or requires research. It sounds thorough and professional.
• “I will verify the details and provide an update.” Best for situations where accuracy is important, such as confirming numbers or facts.

Casual Alternatives

• “Let me look into it and get back to you.” A friendly and natural option for most casual situations.
• “I will check and let you know.” Short, direct, and works in almost any informal setting.
• “I will take a look and get back to you.” Slightly more relaxed than “check,” good for conversations with colleagues.
