Max mail size

The maximum size of an email message, also known as the "maximum mail size" or "email attachment size limit," varies depending on the email service provider, email client, and the type of email being sent.

Here are some general guidelines on the maximum mail size limits for popular email services:

  1. Gmail: 25 MB (25,000 KB) for attachments, with a maximum file size of 10 MB (10,000 KB) for individual attachments.
  2. Yahoo Mail: 25 MB (25,000 KB) for attachments, with a maximum file size of 10 MB (10,000 KB) for individual attachments.
  3. Outlook.com: 20 MB (20,000 KB) for attachments, with a maximum file size of 10 MB (10,000 KB) for individual attachments.
  4. Hotmail: 10 MB (10,000 KB) for attachments, with a maximum file size of 5 MB (5,000 KB) for individual attachments.
  5. ProtonMail: 25 MB (25,000 KB) for attachments, with no maximum file size limit for individual attachments.
  6. FastMail: 50 MB (50,000 KB) for attachments, with no maximum file size limit for individual attachments.
  7. Microsoft Exchange: 10 MB (10,000 KB) for attachments, with a maximum file size of 5 MB (5,000 KB) for individual attachments.

It's worth noting that these limits may vary depending on the specific email account or plan you have with each service provider. Additionally, some email services may have additional restrictions on file types, such as executable files or large multimedia files.

If you need to send larger files, you may want to consider using a file-sharing service or a cloud storage service like Google Drive, Dropbox, or Microsoft OneDrive, which often have larger file size limits and more flexible sharing options.
