Should I Capitalize To Whom It May Concern?

When It Makes Sense

• Good fit: In a formal business letter that follows a sentence‑case style (e.g., Chicago Manual of Style), capitalizing the first word of the salutation – “To Whom It May Concern” – aligns with the surrounding text and looks polished.
• Good fit: When the phrase serves as a heading or title on a printed form or cover page, capitalizing each major word (“To Whom It May Concern”) follows title‑case conventions and improves visual hierarchy.

When You Should Avoid It

• Warning sign: In casual or internal emails where the tone is conversational, using full capitalization can appear overly formal or pretentious.
• Warning sign: If you are writing for a publication that mandates lowercase greetings (e.g., many journalistic style guides), capitalizing the phrase would break the house rules.

Pros and Cons

Pros

• Shows attention to traditional business etiquette, which can convey professionalism to formal audiences.
• Creates visual consistency when the surrounding document uses sentence‑case or title‑case formatting.

Cons

• May look stiff or out‑of‑place in modern, informal communications, potentially alienating the reader.
• Inconsistent capitalization across a document can distract readers and appear careless if style guidelines are not uniformly applied.

Decision Checklist

• Does the document follow a specific style guide (e.g., Chicago, AP, MLA) that prescribes sentence‑case or title‑case for salutations?
• Is the audience expecting a formal business tone, or would a more relaxed approach be appropriate?
• Will the salutation appear as a heading, a line in the body, or within a larger block of text?

Alternatives to Consider

If you want to avoid the capitalization dilemma altogether, you can use a more direct greeting such as “Dear Sir or Madam,” “Dear Hiring Manager,” or simply omit a salutation when the recipient’s name is known. For informal contexts, a lowercase “to whom it may concern” works fine and keeps the tone conversational.

Final Recommendation

When writing formal letters, reports, or any material that follows a sentence‑case or title‑case style guide, capitalizing “To Whom It May Concern” is appropriate and conveys professionalism. In casual emails, internal memos, or publications with a lowercase preference, keep the phrase uncapitalized. Always check the relevant style guide and consider your audience; if uncertainty remains, consult a writing‑style expert or your organization’s editorial policy.
