Optimum online email attachment limit

The optimum online email attachment limit varies depending on several factors, including:

1. Email service provider (ESP): Different email providers have different attachment limits. For example:
   • Gmail: 25 MB (free account), 50 MB (paid account)
   • Outlook.com: 20 MB (free account), 100 MB (paid account)
   • Yahoo Mail: 25 MB (free account), 100 MB (paid account)
   • ProtonMail: 1 GB (free account), 5 GB (paid account)
2. Internet connection speed: Faster internet connections can handle larger attachments, while slower connections may struggle with larger files.
3. Email client or app: Some email clients or apps may have their own attachment limits or restrictions.
4. File type and size: Larger files, such as videos or high-resolution images, may be more likely to exceed attachment limits.

As a general guideline, here are some recommended attachment limits for online email:

• Small files (e.g., text documents, spreadsheets): 5-10 MB
• Medium files (e.g., images, presentations): 10-20 MB
• Large files (e.g., videos, audio files): 20-50 MB
• Very large files (e.g., software, large datasets): 50-100 MB or more

If you need to send larger files, consider the following alternatives:

1. Cloud storage services: Share large files through cloud storage services like Google Drive, Dropbox, or Microsoft OneDrive.
2. File transfer services: Use file transfer services like WeTransfer, File.io, or Hightail to send large files.
3. Email services with larger attachment limits: Consider using email services that offer larger attachment limits, such as ProtonMail or Tutanota.
4. Break up large files: Divide large files into smaller parts and send them separately, or use compression software to reduce the file size.

Remember to always check the attachment limits of your email provider and the recipient's email provider before sending large files.
