Email Limits and Large Attachments: What You Should Know
Emails are an essential communication tool – but every mailbox has its limits. Especially large attachments can quickly become an issue. In this article, you’ll learn how to make the most of the email restrictions in CURIAWEB hosting.
Typical Email Limits
- Maximum size per email: usually 20–25 MB
- Maximum mailbox size: depends on the hosting plan (e.g., 2 GB, 5 GB, or more)
- Number of emails per hour: limited to prevent spam
Why Attachments Can Be Problematic
- File size increases internally by about 33% due to Base64 encoding
- Receiving servers may have different limits
- Multiple large attachments can quickly fill up mailboxes
Alternatives for Large Files
- Cloud file sharing (e.g., Nextcloud, Dropbox, Google Drive)
- Send a link instead of an attachment in the email
- cPanel Webmail with integrated file manager
