“Who” and “whom” still appear in email greetings, but many writers are unsure which one fits. The choice depends on grammar, not formality, and the correct word can make a greeting sound polished without sounding stiff.
In email openings, the decision is usually simpler than people expect. You are choosing between a subject pronoun and an object pronoun, and the structure of the sentence tells you which one belongs.
What “who” and “whom” actually do
“Who” is used for the subject of a verb. “Whom” is used for the object of a verb or a preposition.
That basic rule matters in email greetings because the greeting is often a shortened sentence. Even when the phrase looks incomplete, the grammar still follows the same pattern.
Subject form: who
Use “who” when the person is doing the action. In a full sentence, you would say, “Who is attending the meeting?”
In a greeting, this can show up in lines like “Who should I contact?” or “Who is responsible for approvals?” The word “who” works because it is the subject of “is attending,” “should contact,” or “is responsible.”
Object form: whom
Use “whom” when the person receives the action. In a full sentence, you would say, “Whom did you invite?”
In email writing, “whom” often appears after a preposition or in more formal openings. A greeting such as “To whom it may concern” uses “whom” because it follows the preposition “to.”
Why email greetings create confusion
Email greetings compress language. Writers often begin with a name, a title, or a phrase that is not a full sentence, so the grammar feels less visible.
That compression makes people rely on habit instead of structure. As a result, “who” and “whom” are often chosen by sound alone, which leads to mistakes in formal writing.
Greeting phrases are not always full sentences
“Dear who is handling this case” looks awkward because the grammar is broken. The sentence needs a subject pronoun in a real clause, and “who” would only work if the structure supported it.
Most email greetings are not written that way, though. They usually use a name, a role, or a fixed phrase, which means the writer must judge the grammar inside the phrase rather than the greeting as a whole.
Formality changes expectations
In casual emails, many people avoid both words entirely and use a name instead. “Hi Maria” or “Hello team” is often better than forcing a pronoun into a greeting where it does not naturally belong.
In formal emails, though, the traditional phrase “To whom it may concern” still appears. That phrase survives because it is grammatically correct and widely recognized in professional settings.
When “who” belongs in email greetings
Use “who” when the greeting contains a clause where the person is the subject. This is more common in the body of an email than in the salutation itself, but it can still matter in opening lines.
For example, “Who should receive the updated file?” is correct because “who” is the subject of “should receive.” If you wrote “Whom should receive the updated file,” the sentence would be wrong.
Questions that identify the subject
If the person is performing the action, “who” is the safe choice. A line like “Who can approve this request?” uses “who” because the person is the one doing the approving.
This rule also applies in indirect questions. “Please confirm who is attending” uses “who” because it still refers to the subject of “is attending.”
Relative clauses in greetings
Sometimes a greeting includes a description rather than a direct salutation. A phrase like “Hello to everyone who joined the webinar” uses “who” because the people are the ones who joined.
That structure is useful in segmented email campaigns and internal updates. It sounds natural, and it avoids the awkwardness that often comes from using “whom” where it does not fit.
When “whom” belongs in email greetings
Use “whom” when the person is the object of a verb or follows a preposition. This is the classic case in formal salutations and one of the clearest places where “whom” still appears.
The most common example is “To whom it may concern.” The phrase is formal, specific, and grammatically correct because “whom” follows “to.”
After prepositions
Prepositions are a reliable clue. If the word comes after “to,” “for,” “with,” “about,” or “from” in a formal structure, “whom” may be correct.
For example, “The manager with whom I spoke” uses “whom” because it is the object of “with.” In a greeting context, that same logic supports phrases like “To whom should I address this email?”
As the object of a verb
When a person receives the action, “whom” is the right form. “Whom did you notify?” is correct because the person is being notified.
This pattern matters in professional email threads when you are trying to sound precise. It is especially useful in legal, administrative, and client-facing communication where grammar can affect tone.
The safest way to choose between who and whom
A quick test can solve most cases. Replace the word with “he” or “him,” and the answer usually becomes clear.
If “he” fits, use “who.” If “him” fits, use “whom.” This works because “he” and “who” are subject forms, while “him” and “whom” are object forms.
The he/him test in practice
Try the sentence “___ should I contact?” If you answer “I should contact him,” then “whom” is correct. If the sentence is “___ is responsible?” and the answer is “He is responsible,” then “who” is correct.
This test is especially helpful when the sentence feels formal or old-fashioned. It removes guesswork and keeps the choice grounded in grammar rather than style.
Why the test works in emails
Email greetings often remove part of the sentence, which makes the grammar less obvious. The he/him test restores the missing structure and shows the role the pronoun plays.
That is useful when you are writing under pressure. It takes only a second, and it prevents errors that can make a message look careless.
Common greeting patterns and the correct choice
Some email openings appear so often that they deserve special attention. These patterns show where “who” and “whom” are actually used, and where neither is needed.
Not every greeting needs a pronoun at all. In many cases, a name, department, or title is cleaner and more professional than inserting “who” or “whom.”
“To whom it may concern”
This is the most familiar formal greeting with “whom.” It is correct because the phrase means “to any person concerned,” and “whom” is the object of “to.”
Use it when you do not know the recipient and need a neutral, formal opening. It is common in cover letters, complaint emails, and official requests.
“Hello to everyone who…”
This pattern uses “who” because it describes the people who performed an action. “Hello to everyone who registered early” is grammatically sound.
It works well for newsletters and group messages. The phrase feels inclusive without sounding overly formal.
“For whom this may concern” is not standard
Writers sometimes try to adjust the classic phrase and end up with awkward grammar. “For whom this may concern” sounds unnatural because the original phrase does not work that way.
Stick with the standard form if you need that style of greeting. Changing one preposition often breaks the idiom and makes the sentence worse, not better.
How tone affects the choice in professional email
Grammar is only part of the decision. The level of formality in your email should also guide whether you use a pronoun greeting at all.
In many workplace messages, a direct name is stronger than a pronoun phrase. “Dear Jordan” feels clearer than trying to force a formal construction that may sound dated.
When formal language helps
Formal greetings can be useful when the email is external, sensitive, or highly structured. A legal notice, a complaint, or a job application may benefit from “To whom it may concern.”
That said, formality should serve the message, not dominate it. A greeting that sounds too ceremonial can create distance if the situation calls for warmth or speed.
When simplicity is better
If you know the recipient, use their name. “Hi Priya” is usually better than “Dear whom it may concern,” and it avoids unnecessary grammar questions.
This is especially true in internal communication. Teams usually respond better to direct, human language than to rigid formalities.
Errors that make email greetings sound wrong
One common mistake is using “whom” because the email sounds formal. Formality is not enough on its own; the grammar still has to support the word.
Another mistake is using “who” after a preposition when the person is clearly the object. That creates a sentence that feels casual but is grammatically off.
Using whom as decoration
Some writers insert “whom” to sound smart. That often backfires because the word stands out when it does not fit the sentence.
For example, “Whom should I send this to?” is acceptable in speech and writing, but “Whom is available?” is wrong. The issue is not style; it is grammatical role.
Using who where the object is needed
“Who did you send the invoice to?” is common in conversation, but many editors prefer “Whom did you send the invoice to?” or “To whom did you send the invoice?”
In a formal email, the second version is often the best choice. It keeps the grammar precise and matches the tone of a professional message.
Practical examples for different email situations
Examples are the fastest way to build confidence. The same grammar rule looks easier once you see it applied in real email contexts.
Use these patterns as models, not templates. The best greeting depends on your audience, purpose, and level of formality.
Job applications
“Dear Hiring Manager” is usually stronger than trying to guess a name or use “whom.” If you truly do not know the recipient, “To whom it may concern” can work, but only when the application instructions allow it.
If you are writing to a specific person, use their name instead. That choice is often more effective than any pronoun-based greeting.
Client emails
In client communication, clarity matters more than grammatical display. “Hello Ms. Chen” is direct and respectful, while “To whom it may concern” may feel impersonal unless the recipient is unknown.
If you need a formal opening for a shared inbox or general contact form, “To whom it may concern” remains acceptable. It is still better than guessing incorrectly.
Internal workplace emails
Most internal emails do not need “who” or “whom” in the greeting. “Hi team,” “Hello everyone,” or a person’s name usually works better and keeps the message efficient.
If you are addressing a committee or a cross-functional group, use the group label directly. That avoids unnecessary grammar choices and reads more naturally.
How editors and recruiters notice the difference
People who read emails for a living tend to notice greeting choices quickly. They may not consciously analyze the grammar, but they do register whether the opening feels natural and controlled.
A correct pronoun use can signal care. An incorrect one can distract from an otherwise strong message.
Why precision can support credibility
In applications, pitches, and formal requests, small language choices contribute to trust. A well-formed greeting suggests that the sender pays attention to detail.
That does not mean every email must sound academic. It means the greeting should match the message and avoid avoidable errors.
Why overcorrection can hurt
Some writers try so hard to avoid mistakes that they create unnatural phrasing. That can make an email feel rehearsed or outdated.
Precision is useful, but readability matters more. If a simple name greeting works, it is often the best professional choice.
Best practices for modern email greetings
Use “who” when the person is the subject, and “whom” when the person is the object or follows a preposition. That rule remains the most reliable way to choose correctly.
Then decide whether you need the pronoun at all. In many emails, a name or role is cleaner, faster, and more reader-friendly than a traditional greeting phrase.
Choose clarity first
If the greeting sounds forced, simplify it. The clearest opening is usually the strongest one, especially in business communication.
That may mean replacing a pronoun phrase with a direct address. “Dear Alex” is often better than trying to engineer a formal salutation around “who” or “whom.”
Use formality only when it serves a purpose
Formal greetings have a place, but they should not be used automatically. Their value depends on audience, context, and the relationship between sender and recipient.
When you do need a formal opening, make sure the grammar is correct. “To whom it may concern” remains valid, while awkward variations usually weaken the message.
Read the sentence aloud
Reading the greeting aloud can reveal whether it sounds natural. If the phrase feels strained, the grammar may be wrong or the structure may be too formal for the situation.
This habit helps with both “who” and “whom.” It also improves the overall tone of your email, which matters just as much as technical correctness.
In email greetings, “who” and “whom” are less about memorizing a rule and more about recognizing sentence roles. Once you see whether the person is acting or receiving the action, the right choice becomes much easier.
The best email greeting is the one that is correct, clear, and appropriate for the reader. In many cases, that means using a name instead of a pronoun, but when you do need one, grammar should guide the decision.
