What Is an Email Attachment?

An email attachment is a file accompanying an outgoing email that provides additional content not covered in your email body. The extra information supplements your email, offering greater value and insights to your recipient.

You can attach multiple files to an email message, and the attachment file can be:

  • A PDF or Microsoft Word document.
  • Scanned files.
  • Spreadsheets.
  • Pictures.
  • Videos, and so on.

Next, let’s learn how you can write solid attachment emails in five simple steps.

How to Write an Email with an Attachment

Here are the steps to follow while composing an attachment email:

1. Identify the Files You Want to Send

Before drafting the email, you should know what files you want to attach to your message and where they are located on your device.

This will help you align the message body with the attachment and avoid scurrying around to locate the file last minute.

However, merely identifying these additional files isn’t enough.
You should also consider the potential consequences for your recipients.

What do I mean?
For instance, sending large attachment files that consume too much storage space or take too long to download can turn off recipients and reflect poorly on you.

Instead, you can:

  • Check if your audience is open to receiving your attachments email once you’ve established a connection. While cold emailing new leads, aim to build trust before sending any attachments — you don’t want to upset or overwhelm them with any unexpected attachment.
  • Verify the attachment’s file size and format to ensure they align with your recipient’s preferences.

2. Craft an Email Subject Line

Once you’ve identified the required attachment files, you can begin drafting your email — starting with the subject line.

Since 64% of all readers open an email based solely on its subject line, you’ll have to create a killer subject line that intrigues your audience and reels them in.

And as most recipients tend to overlook unexpected attachment emails, it’s best to mention the file names in your subject line to give them a heads-up.

However, even while adding these details, remember to keep your subject lines concise and to the point, preferably under ten words.

3. Draft the Email Body

Once you have your subject line down, you can move on to the email body.

Your attachment email’s body should provide the recipient with everything you promised in the subject line. It’s here that you explain the purpose of your email.

If your sole intent is to send an attachment file, your email body can be a brief description of the file.

But if the attachment is only a part of what you wish to convey, simply mention it in the body with a short sentence like:

  • Here’s [attachment name].
  • I’m sharing [attachment name] with you.
  • The requested [attachment type – report/video/contract] is attached below.
  • Please take a look at the attached [attachment name].
  • For reference, I’ve appended [attachment name].

Pro tip: Strive to use something besides the generic ‘Please find attached’ when mentioning the attached files in your email’s body.

In addition to mentioning your attached files, your email message body should be compelling enough to interest readers. While drafting the body, you should:

  • Stay focused on your purpose.
  • Relay information through short, concise sentences.
  • Maintain a professional yet engaging tone.

4. Add Attachments Files

Once you’ve composed your email, it’s time to attach the required files to your e mail message.

However, this isn’t a hard and fast rule.
You can actually attach your files whenever you want during the drafting process.

In fact, many senders prefer to attach files before writing their emails so that they don’t forget to attach them later.

But how do you add attachments?
If you’re a Gmail, Microsoft Outlook, or Apple Mail user, attaching files to your message is pretty straightforward.

Here’s a quick walkthrough guide for Gmail (you can follow similar steps for any other email program):

  • Log in to the email server or email client on your desktop or mobile device and click on Compose or New Email option.
  • Click on the Attach File button (attachment icon/ paperclip icon) in the Compose window.

Attach file button

  • Select the files you want to upload and click Open to append the chosen file to your email.

Click open

5. Proofread and Send Your Email

You may have crafted an email with a great subject line and body and even attached the necessary files.

But don’t send it as soon as you finish.

Why not?
Because any minor, overlooked mistake in your email can make you look sloppy and amateur.

For instance, a missing comma, a broken link, or outdated stats can turn off your recipient — or worse, hurt your reputation.

That’s why you should always proofread and review your attachment email before hitting send. You should ensure your emails:

  • Don’t have any grammar or punctuation errors.
  • Are free of typos, broken URLs, or outdated information.
  • Are clear and easy to understand.
  • Address the appropriate recipient.
  • Contain the necessary attachments.

Once you’ve fixed such errors, you can send attachment emails that connect with readers and keep them engaged.

Let’s now look at some handy guidelines to follow while writing emails with attachments.

5 No-Nonsense Tips for Adding Attachments to Emails

Here’re are five actionable tips to enhance your attachment emails:

1. Ensure Your Attachment’s File Format Is Appropriate

A best practice when you send attachment emails is to ensure the file attachment is also accessible to your recipient.

What does that mean?
Just because you can access a file, don’t assume that your recipients would be able to do so too.

Sometimes your readers may not have the required software to open an attachment, leaving them disappointed and frustrated — defeating the purpose of your email.

To raise the odds of your recipient successfully opening the file attachment, you can:

  • Choose a file with a more universal file type they can readily open or download, like a .txt, .jpg, .docx, or .pdf file.
  • Avoid sending attachments with an unfamiliar file extension like .ade, .com, .exe, etc., that need specialized software for access or can raise suspicion among recipients.

2. Limit Your Attachment’s File Size

In addition to file type, your attachment’s size also affects the quality of your attachments email.

Excessively large attachments, especially images, take longer to download and require more storage space. A large file is also more likely to be caught by spam filters and damage your reputation.

And to avoid an influx of large file attachments and spam, every email service provider has size limits for email attachments, such as:

  • Gmail: 25 MB
  • Yahoo Mail: 25 MB
  • Apple Mail: 20 MB
  • Microsoft Outlook: 10 MB

Restricting your attachment size to 10 MB makes it easier for readers to view and download your attachment, especially on mobile devices. If you want to attach multiple files, stick to the upper limit of your specific email service provider.

But what if you have to send a large-sized e mail attachment beyond those limits?
No worries!

Just compress your large attachments as per the limits of your email server or upload them to a cloud storage service like Google Drive, OneDrive, or Dropbox and share the link in your email.

3. Use a Link Instead of an Attachment

Remember, the file format and size restrictions for attachment files can often prevent you from sending them with your e mail message.

You may also prefer to avoid sending any unexpected attachment to new leads since you haven’t yet earned their trust.

What do you do then?
You can send a link to the file stored in a cloud service like Google Drive, OneDrive, or Dropbox) instead of sending an e mail attachment.

I’ll explain why.

Using a link (to a Google Doc, for example) has multiple benefits:

  • It can deliver the same content as an attachment file. For instance, you can share the contents of a Microsoft Word document or Adobe Reader PDF file in a Google doc.
  • It helps you overcome storage and time constraints — sharing a link is quicker and easier than spending several minutes uploading a large file.
  • Recipients can access it online via a desktop or mobile device.

But don’t just copy-paste a link into your email message!

To be professional, you can either:

  • Add a relevant anchor text describing your link’s contents.
  • Use a shortened link or try a URL shortening service like bit.ly to modify any lengthy links.

4. Send Secure Attachments in Your Email

In recent years, attachment emails have become popular channels for malware distribution, posing a massive security threat for recipients.

Sending a malicious or malware-infested file, even accidentally, can compromise your recipient’s email security and undermine your reputation.

But don’t worry. If you exercise caution while sending email attachments, you can save yourself and your recipients a world of pain.

Here’s what you can do:

  • Scan attachments for malware: Most email services automatically scan attached files and reject ones with viruses or malware. If your email client or service fails to do so, install an antivirus program on your computer to weed out virus-infested files.
  • Avoid attaching unknown file formats to your email: Steer clear of file extension types like .ade, .adp   .cmd, .com, .exe, .pcd, .wsf, etc., which are common malware carriers.
  • Stay away from attachment files with double extensions: Extensions like .img.exe are usually misused by hackers to conceal malware and viruses. Beware of any executable attachment file disguised as an image — it’s a common ploy to compromise recipients’ email security.

5. Mention Included Attachments in Your Email

I’ve already discussed the significance of mentioning the attachment’s details in your subject line and email body.

Doing so lets recipients know what to expect from your email message. It’s also an excellent way to be forthright and clear about the purpose of your email.

Some best practices to follow while referring to your attachments:

  • Tell recipients your attached file names.
  • Mention the number of attached files (in case of multiple attachments) and their variations.
  • Include some context or background information to give readers more clarity about the attached file.
