Email
If you need to send a file to someone, the first option should be an Email. But if it is large file, is it safe to send via an email? No, really not.

For security reason most of the email service provider will have message size limit otherwise the email servers bombarded with large mails and cause server down or low performance. The default sending /receiving message size limit of major email service providers are Gmail (25 MB) Yahoo Mail (25MB) and Outlook.com (10 MB).

Even though if you send large attachments via mail, there is a chance to block or bounce back your mail from recipient’s end due to restriction or limited mailbox size especially if they are using hosted solution for an email. This might also cause your mailbox to exceed the storage quota because each mail you sending will be saving on your send items.

Due to this limitation you may receive the following errors when you send large mails

  • 552 Message size exceeds fixed maximum message size
  • Attachment size exceeds the allowable limit
  • The recipient's mailbox is full and can't accept messages now 
So sending large attachments in an email is not a best solution.

The best way to send large files over the internet is file hosting service.  It makes the process simple, you just need to upload the file and share the download links with your recipients. The recommended file hosting service is Google Drive /OneDrive because they offer good storage space (15 GB) with default file size limit (2 GB & 10 GB) for free. If you go for paid one, you will get more. Recommended to read: - Best Free Cloud-Sharing Services
