If you’re wondering how to attach an email in Gmail, you’ve come to the right place. Sharing an email message as an attachment is a quick and efficient way to provide the original message, including its attachments and details, without the need to forward or copy content manually. Gmail offers simple methods such as forwarding an email as an attachment, dragging and dropping emails into the compose window, or using the “Forward as attachment” option found in the three-dot menu.
The attached email is typically saved as an .eml file, which you can save step by step in Gmail and open separately. This allows your recipient to view the message exactly as it was received. Whether you’re replying with an attached email, sharing a conversation thread, or preserving the original email, Gmail makes it easy to attach emails directly from your inbox or message windows.
This step-by-step guide explains the easiest techniques to attach emails, highlights key buttons like the “three dot” menu and the “Pop out reply” button, and provides tips for sharing effectively on desktop and browser versions. With this guide, you’ll gain the confidence to manage your emails efficiently while improving communication using attached emails in Gmail.

When Might You Attach an Email?
Forwarding vs. Attaching Emails
Understanding the difference between forwarding and attaching emails in Gmail is key to effective communication. Forwarding an email sends the content within a new message and allows you to add commentary, but it doesn’t preserve the original email as a standalone file. Attaching an email, on the other hand, includes the email itself as an .eml file attachment.

This means the recipient can open the message exactly as you received it, including all headers and attachments intact. Attaching is especially useful when you want to share the full context or keep the original formatting, while forwarding is simpler for just passing along the content with your input.
Replying with an Attached Email
There are times you might want to reply to an email and include another email as an attachment for reference. Gmail allows you to do this by opening the message window to reply, clicking the “Pop out reply” button, and then dragging the email you wish to attach into the reply window. This attached email will appear as a file named with the subject of the original message, giving your recipient the ability to open and review it independently.

This method is ideal when responding but also needing to share related emails or files without merging threads.
Creating a New Message with an Attached Email
If your goal is to send an email that includes another email as an attachment but not as a reply or forward, Gmail has a straightforward option. From your inbox, select one or more emails by ticking their checkboxes, click the three-dot menu above the inbox, and choose “Forward as attachment.” Gmail will create a new email draft with the selected emails attached as .eml files. You can then add recipients, write your message, and send.

FAQ
How can I attach an entire email as a file in Gmail?
In Gmail, you can attach an entire email as a file by dragging and dropping it into your compose window. This action automatically converts the email into a .eml file. Alternatively, you can select the email, click the three-dot menu, and choose “Forward as attachment.”
Both methods ensure the original formatting, headers, and attachments are preserved.
What should I do if my attachment exceeds Gmail’s 25 MB size limit?
If your attachment exceeds Gmail’s 25 MB limit, you can upload the file to Google Drive and share the link in your email. Another option is to compress the file into a ZIP folder or use a third-party service like WeTransfer or Dropbox to send the file securely.
Why does the attachment option sometimes disappear when composing an email in Gmail?
The attachment option in Gmail may disappear due to outdated apps or browsers, browser cache issues, interfering extensions, firewall or proxy blocks, or Gmail settings such as filters blocking attachments. On mobile devices, UI changes—like attachment icons moving to keyboard bars—can cause confusion. If your messages are missing, check out our guide on fixing missing Gmail messages.
Refreshing Gmail or updating your apps often resolves this issue.
How can I fix issues if Gmail is not sending emails with attachments or if attachments won’t upload?
First, check your internet connection and ensure the files are under 25MB. Update your Gmail app, clear cache and data, and disable VPN or proxy settings.
Additionally, disable browser extensions, try using incognito mode, and ensure there is sufficient device storage. If the issue persists, force close the app or switch to a different browser.
