How to Send a Large File Through Email
Email providers like Gmail, Outlook, or Yahoo often have strict attachment limits (usually between 20MB – 25MB). If your file is larger, you’ll need a secure method to send it without running into delivery issues. Here are the best ways:
1. Use a Secure File Sharing Service
Instead of attaching the file directly, upload it to a tool like SendMega. Once uploaded, generate a secure link and paste it into your email.
Benefit: No size restrictions, encrypted transfers, and faster delivery.
Example: A marketing agency shares a 2GB video project with a client by sending a SendMega download link in Gmail.
2. Use Cloud Storage Links
Services like Google Drive, OneDrive, or Dropbox let you store files in the cloud and share access links via email.
Tip: Always set permissions (view-only or edit) to control access.
3. Compress the File Before Sending
If the file is only slightly above the email limit, compress it into a .zip or .rar folder.
Example: A designer compresses a 30MB set of images into a 10MB zip file for easy email delivery.
4. Split the File Into Smaller Parts
For documents or images, you can break them into smaller chunks and send them across multiple emails.
Best for: Non-urgent transfers or when the recipient has limited internet bandwidth.
Pro Tip: For speed, security, and convenience, the best approach is to use SendMega or another encrypted file-sharing platform, then simply paste the generated link in your email.
Beyond security, a development agency can add custom features tailored to your audience—like AI-driven threat detection, cloud integration, or team collaboration tools. They also provide ongoing support, regular updates, and performance improvements, ensuring your platform stays competitive and ready for future growth.
