How to Refer to an Attachment in Your Next Professional Email

Communication defines professional relationships. When you send an email with a document, the way you refer to that attachment can significantly impact how your message is perceived. Modern business communication has moved away from stiff, archaic legalisms toward a style that is direct, clear, and human-centric.

Quick Reference: The Best Ways to Refer to an Email Attachment

For those looking for a quick solution, here are the most effective phrases to use right now:

Most Versatile: "I’ve attached the [file name] for your review."
Direct and Modern: "Here is the [file name] you requested."
Formal: "Please see the attached [file name] for more details."
Casual: "See attached." or "I'm sharing the [file name] below."

While these phrases work, choosing the right one depends on your relationship with the recipient and the goal of your email. Below, we dive deep into why certain phrases work better than others and how to structure your professional emails for maximum impact.

Why "Attached Please Find" is No Longer Recommended

In the past, "Attached, please find" or "Please find attached herewith" were the gold standard for business correspondence. These phrases originated from the era of physical mail, where a cover letter would literally tell the recipient to "find" additional pages clipped to the back.

In the digital age, this phrasing feels outdated for three main reasons:

Redundancy: Every modern email client (Gmail, Outlook, Apple Mail) uses clear icons, paperclips, and preview panes to signal that a file is attached. The recipient doesn't need to "find" it; it is already visible.
Stiffness: It creates unnecessary distance between the sender and the receiver. Professionalism today is built on clarity and rapport, not on sounding like a 19th-century legal clerk.
Wordiness: In a world of overflowing inboxes, brevity is a virtue. Adding unnecessary words like "herewith" or "please find" slows down the reader’s processing time.

Comprehensive List of Phrases for Different Scenarios

Selecting the right phrase involves assessing the context of the conversation. Our experience in corporate communications suggests categorizing these phrases based on the desired tone.

1. Modern and Direct Phrasing

These are the safest bets for 90% of business emails. They are polite but get straight to the point.

"I’ve attached the [Document Name] for you."
- Why it works: It uses "I," which sounds more personal and takes ownership of the action.
"Here is the [Document Name] we discussed."
- Why it works: It links the attachment directly to a previous conversation, providing immediate context.
"The [Document Name] is attached for your reference."
- Why it works: It’s a neutral, professional way to provide information that the recipient may need later.
"You’ll find the [Document Name] attached below."
- Why it works: It guides the recipient's eye toward the bottom of the email where attachments usually reside.

2. Formal and Client-Facing Phrasing

When writing to a new client, a high-level executive, or a government agency, a slightly higher level of formality is appropriate.

"Please see the attached [Document Name] for further details."
- Why it works: It is respectful and suggests that the document contains essential, in-depth information.
"I am sharing the [Document Name] with you for your consideration."
- Why it works: "Consideration" implies that you value the recipient's opinion or decision-making power.
"Attached is the [Document Name] for your records."
- Why it works: This is specifically useful for invoices, contracts, or receipts where the primary goal is documentation.
"For your convenience, I have included the [Document Name] as an attachment."
- Why it works: It frames the attachment as a helpful gesture, focusing on the recipient’s needs.

3. Casual and Internal Phrasing

If you are emailing a teammate you speak with every day, brevity is usually the highest priority.

"See attached."
- Why it works: It’s the shortest possible way to mention a file. Use this only when the context is already 100% clear.
"Dropping the [Document Name] here."
- Why it works: It reflects the conversational tone of modern tools like Slack or Microsoft Teams.
"Here’s the file."
- Why it works: Simple and efficient.
"Attached: [Document Name]."
- Why it works: Often used at the very end of a short email to signal the file's presence.

The Psychology of the Attachment: Providing Context

Simply stating that a file is attached is often not enough. Based on our analysis of high-performing business workflows, the most successful emails provide a "bridge" between the text and the file.

Why context matters

When a recipient sees an attachment without context, they may hesitate to open it due to security concerns or simply because they don't know how much time they need to dedicate to it.

Instead of saying: "I've attached the report. Let me know what you think."

Try saying: "I've attached the Q3 Marketing Report. Specifically, I'd like your feedback on the budget breakdown on page 4, as we are slightly over our initial projections."

By providing a specific "call to action" related to the attachment, you increase the likelihood of getting a timely and relevant response.

Technical Best Practices for Email Attachments

Referencing the attachment in the text is only half the battle. To ensure your recipient can actually use what you've sent, follow these technical guidelines.

1. Proper File Naming

A file named Document1_v2_final.pdf is unprofessional and confusing.

Bad Case: Resume.pdf (The recruiter has 50 files with this name).
Good Case: Jane_Doe_Marketing_Manager_Resume_2024.pdf.
Bad Case: Stats.xlsx.
Good Case: Project_Alpha_Q3_Budget_Summary.xlsx.

A descriptive file name acts as an additional signpost, reinforcing the message you wrote in the body of the email.

2. Choosing the Right Format

The format you choose determines whether the recipient can open the file across different devices.

PDF (.pdf): The universal standard for professional documents. It preserves formatting regardless of whether it's opened on a phone, Mac, or PC. Use this for resumes, invoices, and final reports.
Word/Docs (.docx): Use only if the recipient needs to edit the document and send it back.
Excel (.xlsx): For data, spreadsheets, and complex calculations.
JPEG/PNG: For images. PNG is generally better for screenshots or images with text due to higher clarity.
ZIP (.zip): If you need to send 10+ files, compress them into a single ZIP folder to avoid cluttering the inbox.

3. Managing File Size

Most major email providers have strict limits:

Gmail: 25 MB
Outlook: 20 MB
Apple Mail: 20 MB
Yahoo: 25 MB

If your attachment exceeds 20 MB, it may be blocked by the recipient’s server without you even knowing. In our testing, the most reliable way to handle large files (like high-resolution videos or massive slide decks) is to upload the file to a secure cloud service (Google Drive, Dropbox, or OneDrive) and include a link in the email instead.

When doing this, you can say: "I’ve uploaded the high-res video files to this [Link Name] folder for you to download at your convenience."

How to Structure an Email with an Attachment

A professional email follows a logical flow. If the attachment is the main reason for the email, the structure should highlight it immediately.

The Subject Line

The subject line should explicitly mention that there is an attachment.

Example 1: "Action Required: Please Review Q3 Budget Draft (Attached)"
Example 2: "Signed Contract for Project Phoenix - [Your Name]"
Example 3: "Invoice #4022 for Services Rendered in October"

The Email Body

Place the reference to the attachment early in the email if it is the primary focus. If the attachment is supplementary, place the reference toward the end.

Scenario: Sending a Report

Greeting: "Dear [Name],"
Context: "Thank you for the productive meeting yesterday regarding the new product launch."
The Referral: "I’ve attached the revised launch timeline as we discussed. This version includes the updated social media milestones."
Call to Action: "Could you please confirm if these dates work for your team by Friday afternoon?"
Closing: "Best regards, [Your Name]"

Real-World Examples of Referring to Attachments

Example 1: Job Application

Subject: Application for Senior Designer Position - Alex Smith

"Dear Hiring Manager,

I am writing to express my interest in the Senior Designer position at [Company Name]. I have attached my resume and portfolio for your review. In these documents, you will find a detailed history of my work with SaaS brands and my recent award-winning campaign for [Previous Company].

I look forward to the possibility of discussing how my skills can contribute to your team.

Best regards, Alex Smith"

Example 2: Sending an Invoice

Subject: Invoice #1234 - [Company Name] - November 2024

"Hi Sarah,

I hope you’re having a great week.

Attached is the invoice for the consulting services provided in November. This includes the four strategy sessions and the final audit report. For your convenience, the breakdown of hours is included on the second page of the PDF.

Thank you for the continued partnership.

Sincerely, Mark Jones"

Example 3: Internal Project Update

Subject: Project Alpha Update: Q1 Projections

"Hi Team,

Great work on hitting our targets this month.

I’m sharing the updated Q1 projections below. I’ve highlighted the areas where we expect the most growth in yellow. Please take a look at the 'Assumptions' tab in the spreadsheet for more context on these numbers.

Let's discuss this further during tomorrow’s stand-up.

Best, David"

Handling Common Attachment Issues

What to do if you forgot the attachment

Everyone has done it: you hit "Send," and immediately realize the "attached" file isn't actually there. The Fix: Don't panic. Send a second, very short email immediately. Subject: Re: [Original Subject] "My apologies—I forgot to actually attach the file in my previous email. Here is the [File Name]. Thank you for your patience!"

Many modern email clients like Gmail now have a "nudging" feature that detects phrases like "I have attached" and warns you if no file is present before you send. Use this to your advantage.

Handling multiple attachments

If you are sending more than three files, list them out in the body of the email to ensure the recipient doesn't miss one. "I’ve attached the following three documents for the closing:

The Signed Sales Agreement
The Property Disclosure Form
The Wire Transfer Instructions"

Conclusion: Clarity Over Formality

Referring to an attachment is less about following a strict set of rules and more about ensuring your recipient has a seamless experience. In modern business, the most "professional" approach is the one that respects the recipient's time and provides the clearest information.

Avoid "Please find attached" and instead opt for "I’ve attached" or "Here is." Combine this with a descriptive file name, a clear subject line, and a specific call to action, and you will ensure your documents are not just received, but read and acted upon.

Summary of Key Points

Modernize your language: Swap "Attached please find" for "I've attached."
Be specific: Tell the recipient exactly what the file is and why they should open it.
Check the technicals: Use PDF for non-editable files, keep sizes under 20MB, and use clear file names.
Structure matters: Mention the attachment early if it's the main point of the email.

Frequently Asked Questions (FAQ)

Is it "Please find attached" or "Please see attached"?

Neither is "wrong," but "Please see the attached [file]" is generally preferred in modern business as it is more direct. "Please find attached" is increasingly viewed as old-fashioned.

Where should I mention the attachment in the email?

If the attachment is the reason for the email (like a resume or an invoice), mention it in the first or second sentence. If it's a supplementary piece of information, mention it at the end of the relevant paragraph or in the closing.

Should I say "See attachment" or "See attached"?

"See attached" (acting as an adjective modifying a hidden noun) or "See the attachment" (noun) are both fine. However, "See attached" is slightly more common in casual or internal business settings.

How do I refer to an attachment if I'm using a mobile device?

Because typing is more difficult on mobile, "Please see the attached file" or "I've attached [File]" is perfectly acceptable. There is no need for extra formality when communicating via mobile.

Is "Attached herewith" still acceptable?

In most industries, no. It is considered extremely archaic and overly formal. The only exception might be in very specific, traditional legal contexts, but even then, modern legal writing is moving toward "plain English."

Can I just send an attachment with no text in the email?

No. This is unprofessional and often triggers spam filters. Always include at least a brief sentence explaining what the file is and who it is from.
