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

If 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 way you say it should change depending on whether you are writing a formal email to a client, speaking to a colleague in a meeting, or texting a friend. This guide gives you direct formal and casual alternatives, explains when to use each, and helps you avoid common mistakes.

Understanding the Tone Difference

The original phrase “I will check and get back to you” is neutral but slightly informal. In professional writing, it can sound too vague or rushed. In casual conversation, it can feel stiff. The key is to match your wording to the relationship and the medium.

Formal Tone

Use formal versions when you are writing to a superior, a client, or someone you do not know well. Formal language shows respect and thoroughness. It often uses longer words and avoids contractions.

Casual Tone

Use casual versions with coworkers you know well, friends, or in quick text messages. Casual language is shorter, uses contractions, and feels friendly.

Neutral Tone

A neutral version works in most emails and conversations where you want to be polite but not overly stiff. It is a safe choice when you are unsure of the formality level.

Common Mistakes

English learners often make these errors when using this phrase.

Mistake 1: Using “revert” incorrectly

Some learners write “I will revert back to you.” In formal English, “revert” means to return to a previous state, not to reply. Use “get back to you” or “follow up” instead.

Correct: I will get back to you with the details.

Mistake 2: Being too vague

Saying “I will check and get back to you” without a time frame can frustrate the other person. Add a specific time when possible.

Better: I will check and get back to you by 3 PM.

Mistake 3: Mixing formal and casual in the same sentence

Avoid combining a formal word with a casual phrase, such as “I shall check and let you know.” It sounds unnatural. Choose one tone and stick with it.
