How to Write a Professional Letter with Attached Documents (With Examples)

Understanding the Basics of a Letter with Attached Documents

What is a sample letter with attachments?

A sample letter with attachments is a formal or professional correspondence that includes additional documents referenced within the main body of the letter. These supporting materials could range from resumes and contracts to invoices, reports, or legal paperwork. The letter serves as both a cover note explaining the purpose of the attachments and a guide for the recipient on how to interpret the enclosed documents. In professional settings, such letters follow specific formatting conventions to ensure clarity and maintain a polished appearance.

When to use a formal letter with enclosures

Formal letters with enclosures are appropriate in various business and official scenarios, including:

• Job applications (resume, cover letter, references)
• Contract submissions or proposals
• Legal documentation submissions
• Financial transactions (invoices, receipts, statements)
• Academic or research paper submissions
• Grant or funding applications

According to recent business communication studies, nearly 40% of recipients won’t open an attachment if the accompanying email lacks clear context, emphasizing the importance of a well-crafted cover letter.

Key differences between a cover letter and a business letter with attachments

While both serve as introductory documents, a cover letter is specifically tailored for job applications, focusing on the applicant’s qualifications and interest in a position. A business letter with attachments has broader applications and typically:

• References multiple documents rather than focusing on one primary attachment
• Follows more formal business letter formatting standards
• Often requires specific notation of enclosures
• May include legal or technical language depending on the context

Essential Components of a Professional Letter with Enclosures

Proper formatting for a business letter with attachments template

A professionally formatted letter with attachments should include:

1. Your contact information (letterhead or personal details)
2. Date of writing
3. Recipient’s address
4. Formal salutation
5. Clear subject line or reference
6. Concise body paragraphs
7. Enclosure notation
8. Professional closing

PDF remains the most commonly attached file type in business correspondence, used in 78% of cases due to its universal compatibility.

How to clearly mention attached files in your letter

When referencing attachments, be specific and systematic:

• Use phrases like “Please find attached” or “Enclosed please find”
• Number and name each document clearly
• Briefly explain the purpose of each attachment
• Place the reference in a prominent position, typically early in the letter

Research shows that including “see attached” in the subject line increases open rates by 17%, as it signals actionable content to recipients.

The importance of referencing supporting documents

Proper document referencing serves multiple purposes:

• Helps recipients verify they’ve received all necessary materials
• Provides context for how to interpret each document
• Creates a paper trail for legal or official purposes
• Demonstrates professionalism and attention to detail

Step-by-Step Guide to Writing a Letter with Additional Documents

Step 1: Drafting the main content of your letter

Begin with a clear purpose statement in the opening paragraph. Explain why you’re writing and what action you expect from the recipient. Keep the tone professional yet approachable, and ensure all critical information is included in the body text, not just in attachments. Over 60% of professionals admit spending more time formatting attachments than writing the cover content, so balance your effort appropriately.

Step 2: Properly listing and describing enclosures

Create a numbered or bulleted list of all attachments, including:

• Document titles (exactly as they appear in the files)
• Brief descriptions of each document’s purpose
• Version numbers or dates if relevant
• Page counts for lengthy documents

Step 3: Formatting attachments for professional correspondence

Prepare your documents with these guidelines:

1. Use standard file formats (PDF preferred for most cases)
2. Name files logically (e.g., “Doe_J_Resume_2023.pdf”)
3. Ensure all documents are properly paginated
4. Verify that digital files aren’t password-protected unless necessary

Step 4: Final checks before sending your letter with documents

Before submission, verify:

• All referenced attachments are actually included
• File names match those mentioned in the letter
• No confidential information is accidentally included
• The complete package makes logical sense to an outside reader
