We continuously monitor our email servers in order to ensure that emails are delivered to the recipients of your files. If they (or you) don't receive emails, then please check your SPAM folder (or CLUTTER folder in case you're using Outlook)
If you have a Gmail account - then please check your Promotions tab:
You can also copy the Download URL - and send this unique URL to recipients using your own email account. The download URL is the browser address which is displayed when you are on the download page - and looks something like this: http://www.filemail.com/d/asdfasdfasdfasd
Another alternative is to use our Outlook Addin. All emails are sent from your own account when using this Addin - so the emails will be delivered as any other email you send.
