Many people wonder who to contact or whom to contact when they need help. This question mixes grammar and etiquette. Writers want to sound correct and polite. Speakers want to be clear and natural.
This article explains the grammar, gives simple rules, and shows real examples. I will mark parts of speech, check verbs, and give templates you can use.
Paragraph with parts-of-speech analysis
- People often ask whether to write who to contact or whom to contact in emails and forms.
- The choice depends on grammar and tone.
- Whom is the object form and is correct when the pronoun receives the action.
- Who is the subject form and is correct when the pronoun does the action.
- Many speakers use who to contact in speech because it feels natural.
- In formal writing, whom still appears in questions and prepositional phrases.
- This article gives clear rules, examples, and quick tests to choose the right word.
People often ask whether to write who to contact or whom to contact in emails and forms
- Nouns: People, emails, forms (things/people).
- Pronouns: who, whom (relative/interrogative pronouns used in quoted phrases).
- Verbs: ask (present tense; subject People is plural — correct), to write (infinitive; used after ask whether — correct).
- Adjectives: none.
- Adverbs: often (modifies ask).
- Prepositions: in (introduces emails and forms).
- Conjunctions: or (joins alternatives).
The choice depends on grammar and tone
- Nouns: choice, grammar, tone.
- Verbs: depends (third-person singular present; subject The choice — correct).
- Adjectives/adverbs: none.
- Prepositions: on (part of depends on).
Whom is the object form and is correct when the pronoun receives the action
- Pronouns: Whom (pronoun being defined), the pronoun (noun phrase referring to interrogative pronoun).
- Verbs: is (linking verb, singular — correct), receives (third-person singular present; subject the pronoun — correct).
- Nouns: object form, action.
Who is the subject form and is correct when the pronoun does the action:
- Pronouns: Who (subject pronoun being defined).
- Verbs: is (linking verb — correct), does (third-person singular; subject the pronoun implied — correct).
Many speakers use who to contact in speech because it feels natural:
- Nouns: speakers.
- Verbs: use (present plural; subject Many speakers — correct), feels (third-person singular present; subject it — correct).
- Conjunctions: because (introduces reason).
In formal writing, whom still appears in questions and prepositional phrases:
- Nouns: writing, questions, phrases.
- Verbs: appears (third-person singular; subject whom — correct).
- Adjectives: formal, prepositional.
This article gives clear rules, examples, and quick tests to choose the right word:
- Nouns: article, rules, examples, tests, word.
- Verbs: gives (third-person singular; subject This article — correct), choose (base verb after to — correct).
— All verbs are correct for tense and subject-verb agreement. Sentences are complete and not run-on. Parts of speech are identified for clarity.
Quick answer: who vs whom
- Use who when the pronoun is the subject of a clause (it performs the verb).
- Example: Who called you? (who = subject)
- Use whom when the pronoun is the object of a verb or preposition (it receives the action).
- Example: Whom did you call? (whom = object)
- If you are not sure, try the he/him test: replace who/whom with he or him. If him fits, use whom. If he fits, use who.
The he/him test (simple and reliable)
This test works in most cases.
- Replace who or whom with he or him as if you were answering the question.
Examples:
- Question: “Who/Whom did you see at the store?”
- Test: “I saw him.” → use whom → “Whom did you see at the store?”
- Question: “Who/Whom called the meeting?”
- Test: “He called the meeting.” → use who → “Who called the meeting?”
- Phrase: “To who/whom should I address the letter?”
- Test: “I should address the letter to him.” → use whom → “To whom should I address the letter?”
Why it works: he is a subject pronoun; him is an object pronoun. Who pairs with he; whom pairs with him.
Who/whom in questions vs embedded clauses
Direct questions:
- “Who told you?” — who = subject.
- “Whom did they choose?” — whom = object.
Embedded questions or reported speech:
- In less formal English, speakers say “I don’t know who to contact.” That is common and acceptable in speech.
- Formally, you could say “I do not know whom to contact.” The object form whom is grammatically correct because it is the object of to contact.
Examples with POS and verb checks:
- Direct: “Who is responsible for the report?”
- Who (subject pronoun), is (verb present singular), responsible (adjective), for (preposition), the report(object). Verb agreement correct.
- Direct: “Whom did you invite?”
- Whom (object pronoun), did (auxiliary past), you (subject), invite (base verb). Verb usage correct.
- Embedded: “I know who wrote the report.”
- I (subject), know (verb), who (subject of embedded clause), wrote (verb past), the report (object). Correct.
- Embedded formal: “I know whom to contact about this issue.”
- I (subject), know (verb), whom (object of infinitive to contact), to contact (infinitive), about this issue(prepositional phrase). Verb agreement correct.
Common sentence patterns where whom is correct
- After a preposition: Prepositions require object pronouns.
- “To whom should I speak?” — whom is object of to.
- POS: To (preposition), whom (object pronoun), should (modal), I (subject), speak (verb). Correct.
- As the direct object of a verb:
- “Whom did she hire?” — whom receives the action hire.
- POS: Whom (object), did (aux), she (subject), hire (verb).
- As the indirect object (less common):
- “Whom did you give the message to?” → better: “To whom did you give the message?”
- POS: To (preposition), whom (object of preposition), did give (aux + verb), you (subject), the message(object).
- In formal fixed expressions:
- “Whom it may concern.” — whom is object of concern; traditional business phrase.
Why many speakers avoid whom
- Natural speech prefers simpler forms. People say “Who should I contact?” more than “Whom should I contact?”
- Whom can sound formal or old-fashioned. That is why many native speakers use who even when whom is grammatically correct.
- In writing, choose formality based on audience. In formal letters or official documents, use whom. In casual emails and conversation, who is fine.
Examples with POS, verb checks, and rewrites
I provide common sentences with notes and corrections.
Email subject line
- Draft: “Who to contact for support?” (common, informal)
- POS: Who (pronoun), to contact (infinitive), for (preposition), support (noun). This is a fragment but acceptable as a headline or subject.
- Formal rewrite: “Whom should I contact for support?”
- POS: Whom (object pronoun), should (modal), I (subject), contact (verb), for support (prepositional phrase). Verb checks correct.
Website FAQ
- Common: “Who do I contact about billing?” (informal)
- POS: Who (object pronoun used colloquially), do I contact (aux + subject + verb), about billing (prep phrase).
- Formal: “Whom should I contact about billing?”
- POS: Whom (correct object), should I contact (modal question). Both are grammatically valid; the second is more formal.
Embedded clause
- “I need to know who to contact.” (informal and accepted)
- POS: I (subject), need (verb), to know (infinitive), who (subject of infinitive clause in colloquial use), to contact (infinitive).
- Formal: “I need to know whom to contact.” (more prescriptive)
- POS: whom (object of to contact). Verb checks: need matches subject I.
Prepositional placement
- Casual: “Who are you going to send this to?”
- Ends with preposition; informal. Many speakers accept it.
- Formal: “To whom are you going to send this?”
- Preposition fronted, whom is object; sounds more formal. Verb check: are matches subject you.
Who vs whom: style and register guide
- Formal writing (business letters, academic writing): Use whom when it is the object. Example: Whom should we invite? To whom should the letter be addressed?
- Neutral/colloquial writing (email, blog, messaging): Who is acceptable and common. Example: Who should we invite? Who do I contact?
- Journalistic style: Many style guides (AP) allow dropping whom in many situations. Check the style guide you follow.
Practical rule: if your audience values formality or the text is official, use whom. If your audience is casual or the tone is conversational, use who.
American vs British English differences
- Both dialects follow the same grammatical rule: who = subject, whom = object.
- British English may sustain traditional grammar longer in formal contexts; whom can sound less archaic in Britain.
- American English in everyday speech often drops whom; journalists and bloggers favor simpler who.
- For international clarity, the he/him test works everywhere.
Common mistakes and fixes
- Mistake: “Who should I send the form to?” (informal ending-preposition)
- Fix (formal): “To whom should I send the form?”
- Note: The informal line is widely accepted in speech.
- Mistake: “Whom is coming to the meeting?”
- Why wrong: Whom is object form; the pronoun is subject here.
- Fix: “Who is coming to the meeting?”
- POS: Who (subject), is coming (verb phrase).
- Mistake: “I don’t know whom wrote the memo.”
- Why wrong: Whom cannot be subject of wrote; use who.
- Fix: “I don’t know who wrote the memo.”
- Mistake: “Who should I give the report to?” (informal)
- Formal fix: “To whom should I give the report?”
- Mistake: “He is the person whom helped me.”
- Why wrong: whom used as subject; wrong.
- Fix: “He is the person who helped me.”
Use the he/him test to catch these errors quickly.
Idiomatic expressions and fixed phrases
Some expressions traditionally use whom in set phrases:
- To whom it may concern — standard business salutation.
- For whom the bell tolls — literary phrase (from John Donne / Hemingway).
- Whom God has joined — in some religious contexts.
These are formal or literary. In everyday speech, such forms are rare.
Practical templates and polite phrasing
Use these templates in emails and messages.
Informal / friendly:
- “Who should I contact about X?”
- “Who do I talk to about refunds?”
- “Who can help me with this issue?”
Formal / polite:
- “To whom should I address this inquiry?”
- “Whom may I contact about billing matters?”
- “Please advise whom I should contact regarding this request.”
Neutral / safe: (works almost everywhere)
- “Who should I contact regarding X?” — acceptable in most settings.
- “Please let me know the appropriate contact for X.” — avoids the who/whom question entirely.
Politeness tip: Use “please” and “could you tell me” to make requests warmer.
Rewrite: make sentences clearer and more polite
Below are rough lines and polished variants.
Original (rough): “Who to contact for refunds?” (headline) Polished (email): “Could you tell me whom I should contact about refunds?” — formal Polished (casual): “Who should I contact about refunds?” — simple and natural
Original (rough): “I don’t know who to give this to.” Polished: “I don’t know whom to give this to.” — formal Alternate neutral: “I don’t know who the right contact is for this.” — avoids ending preposition
Original (rough): “Please advise who is the best person.” Polished: “Please advise who the best person to contact is.” — clearer Or formal: “Please advise whom I should contact.” — concise and formal

Conclusion
who to contact or whom to contact depends on grammar and tone. Use who when the pronoun is the subject. Use whom when the pronoun is the object of a verb or preposition. The he/him test helps: if him fits, use whom; if he fits, use who. In speech and casual writing, who to contact is common and acceptable. In formal writing and official letters, prefer whom. If in doubt, rephrase to avoid the problem: “Please let me know the appropriate contact.” Clear grammar, correct verbs, and polite phrasing will make your message effective.
FAQs
1. Can I say “Who should I contact?” Yes. In speech and informal writing, this is natural. For formal contexts, Whom should I contact? is more traditional.

3. What is the he/him test? Replace who/whom with he/him. If him fits, use whom; if he fits, use who.
4. Does ending a sentence with a preposition make it wrong? No. Ending with a preposition is fine in modern English, especially in speech. Formal writing may prefer moving the preposition earlier: To whom should I send this?
