As electronic communication continues to grow, and online collaboration becomes a business norm, the sharing of large files becomes a practical necessity. Originally, e-mail was not designed to accommodate large file transfers, and implementing this functionality became much easier said than done.

As time progresses, people need to share larger files. Traditional e-mail cannot accommodate this need. One of the major issues is that with ‘push’ architecture, large file sizes can bog down a recipient’s e-mail access, as enormous files are downloaded at the same time as relatively tiny text-based e-mails.

email2 effectively solves this problem by fundamentally rejecting the ‘push’ architecture and adopting a more user-based ‘pull’ architecture. Users are not forced to download unwanted files, nor are they forced to download attachments in order to retrieve the rest of their email messages. Large attachments can be downloaded at a user’s leisure.

Attachments are stored on the Private Email Networks (PEN) encrypted in multiple pieces. Because of this, and because email2 relies on HTTPS (128-bit encryption SSL) instead of standard e-mail protocols, an integrated download accelerator is used to download several pieces of the same file in parallel. This substantially reduce the time required to download large files; in some cases, download speeds can be increased up to 400%.

Additionally, reliance on an HTTPS based ‘pull’ architecture eliminates download size restrictions. Users can attach and retrieve files as large as they would like, provided that they have the bandwidth and network resources to accommodate such transfers, directly in their Outlook client.
