Attach as many files as you want no matter how large. A link to the files is added to the email, and files are being uploaded to our service. BUT you don't have to wait for the files to be uploaded before you can send the email. So you can attach as many and as large files as you want without waiting for them to upload.

Would love some feedback on this if you have any.
