Alternative to sending large files over email
Have you ever needed to send a large zip file or image file over email to someone? Then you know how much of a pain it can be with various email servers blocking large attachments and download wait times. You could wait all that time for the email to finish sending to only to discover that it was blocked.
There are a lot of people who do not realize there is a much easier way to send this bigger files. You just have the file uploaded to your website and instead of sending the file as an attachment, send a link to the file that was uploaded to your site. Almost always this will save you time. Files upload and download to web servers much quicker than they can be sent over email.
This also allows you to send one file to multiple recipients without bogging down your server, your email client, or the recipients email client.
