The phrase "To Whom It May Concern" is capitalized with the first letter of each main word capitalized: T, W, I, M, C. This style is because the phrase acts like a proper noun or title in formal correspondence. It is always followed by a colon (:) rather than a comma or period. The salutation should stand on its own line, with a blank line before the body of the letter or email begins. Summary of capitalization and formatting rules:
- Capitalize each main word: "To Whom It May Concern"
- Follow with a colon: "To Whom It May Concern:"
- Place on its own line, then leave a blank line before starting the letter text
This capitalization is considered standard professional etiquette for formal or generic salutations when the recipient's name is unknown.
