Word Confusion: Attachment versus Enclosure (in a Business Letter)

Posted July 26, 2022 by Kathy Davie in Author Resources, Self-Editing, Word Confusions, Writing

I ran across a website, the Business Writing Blog, stating that attachments vs enclosures are different. I don’t know about you, but I had no clue. Faraday states that understanding the difference between the two will give your work a more competitive edge and a sense of professionalism. It is a small detail, but one that separates the experienced from inexperienced office worker.

An attachment never stands alone and is an explanation or an extension of the letter’s content and can highlight its key points with the writer referring to the documents attached in a business letter. It is an external document that sheds more light on the content of the business letter, e.g., a data spreadsheet detailing more information or bank information confirming a particular financial claim.

Attachments are frequently referred to alphabetically, e.g., “Attachment A”. If you do choose the alphabet, be sure to include the reference on the actual attachment in the header.

An enclosure stands alone even though they are included in the letter but not necessarily referred to in the letter. Examples of enclosures include a cover letter for your résumé, a brochure, photos, certificates, a market survey chart, etc.

Additional Pointers When Dealing With Attachments/Enclosures

Type your attachment/enclosure two line breaks below your name or signature.

Use the title of the document(s) as the title of the attachments/enclosures if you are listing them — and as they appear in your document. You want the recipient to easily understand which document is what.

By noting your attachments/enclosures as they appear, everything is kept in order and are as clear and concise as possible making for a better organized and more easily accessible document.

Restrain from including too many attachments/enclosures when writing a business letter. If you include too many, the recipient may feel overwhelmed and not even look at them. And sometimes ya just gotta go for broke, so if you need a second page to note all the attachments/enclosures, indicate “Attachments: Page 2” at the top of the second page. And “Attachments: Page 3”, “Page 4”, etc., lol.

And just to confuse things even more, use attachment(s) with emails, but not enclosure(s), because of the mechanics of attaching files to an electronic letter/memo.

Word Confusions . . .

. . . started as my way of dealing with a professional frustration with properly spelled words that were out of context in manuscripts I was editing as well as books I was reviewing. It evolved into a sharing of information with y’all. I’m hoping you’ll share with us words that have been a bête noire for you from either end.

History of the Word

An external document(s) or file(s) always mentioned in the letter (and considered part of the letter), as enhancing or further explaining information contained in the letter

  • A computer file appended to an email, as a downloadable item
A document or object placed in an envelope together with a letter but not necessarily referred to or explained in the letter — and it is considered a separate document, NOT part of the letter
Examples:
There is an attachment, a data spreadsheet detailing statistics in the bank information, confirming your financial claim.

See the attached contract for further information.

Both of these attachments offer explanations or are an extension of the letter’s content and can highlight its key points.

Be sure to include a cover letter as an enclosure when you send out your résumeé.

Hey, Jim, be sure to send that market survey chart as an enclosure.

Always include a brief enclosure citation to alert the reader that there is/are additional document(s) that come with the letter.

Citing
Citing refers to noting your attachments/enclosures that you are including two line breaks below the writer’s name at the bottom of the letter/email.

This helps the recipient navigate your content with minimal effort.

Not to mention, citing an attachment/enclosure lets a recipient know when they may be missing a document.

It also makes a useful checklist so you can ensure you’ve included everything.

Informal
In an informal letter to someone, in the body of the letter, inform the recipient that you attached/enclosed something — or how many somethings.
Government Correspondence Formal
Place attachment citations at the bottom of letters, usually two line breaks below the writer’s signature or initials.

  • In a letter, use “Enclosure”.
  • In a memo, use “Attachment”.
Place enclosure citations at the bottom of letters, usually two line breaks below the writer’s signature or initials.
Referring to Attachment in Body of Letter/Email
Whether using email or a hard copy letter, cite the information from your attachment in the body of the letter using parentheses or commas to encase the file or document name and any relevant date.

  • Use the name of the document, which is, hopefully, easy to read, or
  • Use an alphabetic name, i.e., Attachment A, which should also be typed on the actual attachment so the reader can identify it.

, Attachment: Customer Service Journal, 1/5/2017,

Citing Examples:
Some business writers suggest enclosing the enclosure citation in parentheses; some don’t recommend the parentheses. Whichever you choose, be consistent.
