How to Send a Large File via Email

To send a large file via email, you cannot simply attach it if it is bigger than your email provider’s size limit, which is commonly around 25MB. Instead, you should upload the file to a cloud storage service or compress it, then share a download link or smaller file in your email. This article explains why this issue arises, gives detailed steps to send large files, shows a worked example, lists common mistakes, and explains how HelloGrowthCRM can help with related email communications.

Why this comes up / what goes wrong

Small businesses often need to send large files like contracts, images, videos, or reports to clients or partners. Email providers limit attachment sizes to prevent server overload and security risks. For example, Gmail and Outlook usually cap attachments at 25MB. (support.google.com) Trying to attach a file larger than this results in an error or failed send. Without a clear method, business owners might resort to splitting files, using multiple emails, or sending unsecured links, which can cause confusion, delays, or data breaches.

Step-by-step

1. Check your email provider’s attachment size limit. Find this in your email settings or help pages. If your file is smaller, attach it directly.

1. Compress the file if possible. Use file compression software (e.g., ZIP) to reduce size. Check the new size. If it’s still too large, proceed to step 3.

1. Upload the file to a cloud storage service. Use services like Google Drive, OneDrive, Dropbox, or your business’s preferred cloud storage. Sign in, upload the file, and wait for the upload to complete.

1. Set sharing permissions. Make sure the link you generate allows the recipient to view or download the file without needing to sign in, unless you want added security.

1. Copy the shareable link. Most services provide a clear “Copy link” button.

1. Compose your email. Instead of attaching the file, paste the link in the body of your email with a clear explanation of what the file is.

1. Check your email before sending. Confirm the link works by opening it yourself in an incognito browser window.

1. Send the email. Your recipient can now download the large file securely.

1. Follow up if needed. Use email automation and sequences to remind the recipient if they haven’t replied, available in some CRMs like HelloGrowthCRM (email automation and sequences).

Example (fictional figures)

A letting agency in Manchester needs to send a 45MB video walkthrough of a property to a prospective tenant on 15/05/2026.

• File size: 45MB
• Email attachment limit: 25MB

Step 1: File is too large to attach directly.

Step 2: Compressing the video reduces size to 40MB, still too large.

Step 3: Upload video to Google Drive.

Step 4: Set sharing to "Anyone with the link can view".

Step 5: Copy link: https://drive.google.com/abc123

Step 6: Compose email:

"Dear Client, please find the property video walkthrough here: https://drive.google.com/abc123"

Step 7: Test link in incognito browser — works.

Step 8: Send email.

Step 9: Set automated follow-up sequence in HelloGrowthCRM to check if the client has viewed the email (email automation and sequences).

Common mistakes

• Trying to attach files larger than the limit. Prevent by checking size first.
• Forgetting to set correct sharing permissions. Recipient may get access denied. Always test the link.
• Sending the link without explanation. Recipients may ignore or distrust it. Always describe the file.
• Not compressing files when possible. Compression can save time and bandwidth.
• Using unsecured or unfamiliar file sharing services. Use trusted providers to protect data.
• Not following up after sending. Use automated sequences to ensure the recipient received and accessed the file (email automation and sequences).
