Who to Contact vs Whom to Contact: Which One Should You Use?

English grammar often creates confusion, especially when it comes to choosing between who and whom. One of the most common questions people ask is whether they should write who to contact or whom to contact. You’ll see both expressions in emails, business documents, websites, and everyday conversations, making it difficult to know which one is actually correct.

The good news is that both phrases can be correct depending on the context and level of formality. However, modern English has shifted toward using who in many situations where whom was once expected. This guide explains the difference in plain English, provides practical examples, and helps you choose the right expression with confidence.

Quick Answer

“Who to contact” is the preferred choice in modern English and sounds natural in both speech and writing. “Whom to contact” is grammatically formal because whom functions as an object. While both are correct, who to contact is far more common in everyday communication.

Why People Confuse It

Many English learners—and even native speakers—struggle with who and whom because modern English rarely uses whom in casual conversation.

Here are the main reasons:

• Both phrases appear in books and online.
• Schools often teach traditional grammar rules.
• Modern spoken English favors who.
• Formal writing sometimes still prefers whom.
• Many people aren’t sure when a pronoun is an object.

As a result, people often wonder whether grammar rules or natural usage should guide their writing.

First Word: Who to Contact

Who to contact is the expression you’ll hear most often today.

Although traditional grammar says whom should be used as an object, who has become widely accepted in everyday English—even when it’s technically an object.

Examples include:

• Please ask who to contact for technical support.
• I don’t know who to contact about the refund.
• The guide explains who to contact in an emergency.
• Tell me who to contact if I have questions.

This version is appropriate for:

• Emails
• Websites
• Customer service pages
• Business communication
• Everyday conversations

Second Word: Whom to Contact

Whom to contact follows traditional English grammar because whom is the object of the verb contact.

You’ll mostly find it in:

• Legal documents
• Academic writing
• Government publications
• Formal business correspondence

Examples:

• The handbook explains whom to contact for further information.
• Applicants should know whom to contact regarding visa questions.
• The policy outlines whom to contact during emergencies.

Although grammatically precise, it can sound overly formal in everyday conversation.

Common Mistakes

Avoid these frequent errors:

Using “whom” just to sound smarter

Incorrect:

• Whom is coming today?

Correct:

• Who is coming today?

Thinking “whom” is always better

Modern English doesn’t require whom in most situations.

Avoiding “whom” completely

In formal writing, whom still has an important place.

Using the wrong level of formality

Match your grammar to your audience.

Memory Trick

Here’s an easy way to remember the difference.

• Who = he
• Whom = him

If him sounds correct, whom is traditionally correct.

Example:

You should contact him.

↓

You should know whom to contact.

However, remember that modern English often replaces whom with who, especially in conversation.

American vs British English

Both American and British English increasingly favor who over whom in everyday communication.

American English

• Strong preference for who to contact
• Whom mainly appears in formal writing

British English

• Similar trend toward who
• Whom survives slightly more often in official documents and formal publications

In both varieties, using who to contact is considered perfectly natural.

Final Verdict

Choose whom to contact when writing formal documents or when following traditional grammar conventions. Both expressions are correct, but selecting the right one depends more on your audience and tone than on strict grammar alone.

Conclusion

Understanding the difference between who to contact and whom to contact doesn’t have to be difficult. Traditional grammar favors whom because it acts as the object of the verb, but modern English increasingly accepts who in the same position. As a result, who to contact has become the standard choice for everyday communication.

The best approach is to match your language to your audience. For emails, websites, and general business writing, who to contact sounds natural and approachable. For legal, academic, or highly formal documents, whom to contact remains an appropriate and grammatically precise option.

Remember This

Use “who to contact” for everyday English and professional communication. Use “whom to contact” when you want a more formal, traditional grammatical style.
