This guide explains the grammar rules, examine real-world examples, and give you practical tools for confident communication.
Who to Contact or Whom to Contact – Which One Is Correct?
The grammatically correct phrase is “whom to contact.” Grammar rules state that “whom” functions as an object pronoun, meaning it receives the action in a sentence.
You (the subject) are doing the contacting, and “whom” is the person receiving that contact. The structure follows subject-verb-object order.
“Who to contact” breaks traditional grammar rules because “who” is a subject pronoun. Using two subject pronouns (“who” and “I”) in the same sentence creates confusion about which one performs the action.
That said, modern usage has made “who to contact” acceptable in casual conversations, emails to friends, and informal workplace communication. Language evolves, and strict grammar rules have relaxed over time.
| Phrase | Grammatical Status | Best Used For |
| Whom to contact | Formally correct | Business letters, academic writing, professional emails |
| Who to contact | Informally accepted | Casual emails, everyday speech, friendly conversations |

“Who” vs. “Whom” – The Grammar Rule Behind It
Subject pronouns (who, I, he, she, they) perform actions in sentences.
Object pronouns (whom, me, him, her, them) receive actions.
The word “whom” serves as the object receiving the verb’s action. When you contact someone, that person becomes the object of your action. Therefore, “whom” fits the object position.
“Who” performs actions rather than receives them. Saying “who should I contact” puts two subjects in one sentence without clearly identifying the object.
If you can replace the word with “him” or “her,” use “whom.” If you can replace it with “he” or “she,” use “who.”
English has gradually simplified over decades. The word “whom” appears less frequently in spoken language because it sounds formal or old-fashioned to many speakers. Business writing and academic contexts still prefer grammatical precision.
The He/Him Trick – Never Confuse Who and Whom Again
This simple replacement method works every time. Rephrase your question as a statement using “him” or “he.”
If “him” fits naturally, use “whom.” If “he” sounds correct, use “who.” Both words end in “m,” making this an easy memory tool.
Example 1: Should I contact him? (Him works → Use whom)
- Correct: Whom should I contact?
Example 2: He will contact me. (He works → Use who)
- Correct: Who will contact me?
The him/he replacement never fails because both sets follow identical grammatical patterns.
When to Use “Who to Contact” vs. “Whom to Contact”
| Scenario | Recommended Phrase | Reason / Notes |
| Professional business emails | Whom to contact | Shows attention to grammatical detail; expected in formal correspondence with clients and supervisors |
| Academic writing | Whom to contact | Required in research papers, dissertations, and scholarly articles; strict grammatical standards |
| Customer service | Who to contact | Sounds friendlier and more approachable; clarity is prioritized over strict grammar |
| Casual workplace communication | Who to contact | Suitable for team chats, quick emails, and internal memos; matches relaxed office tone |
| Job applications / cover letters | Whom to contact | Creates a professional impression; hiring managers notice grammatical choices |
| Everyday conversations | Who to contact | Aligns with spoken language trends; “whom” is rarely used in casual speech |
