Email File Attachment Limits
Having problems transferring large files? Accellion’s secure large file transfer solution solves all of them.
Large email attachments are clogging up email servers
In case anyone hadn’t noticed—emailing a file attachment larger than 10MB is no longer feasible in most organizations. Incredible really, given that email is the de facto standard for enterprise communication and collaboration and that as email usage has increased exponentially, so has the size and volume of email file attachments. The problem that many businesses are discovering is that email was not designed to act as a primary file transfer server for large file attachments. These large files can, and do, quickly congest the entire email network, slow down productivity, and leave businesses exposed to severe security risks.
All it takes is one large email attachment to slow the entire network
Yes, it’s true. One large file attachment can cause an enterprise email network to slow down. Even a medium size file sent to a large distribution list can disrupt email and other critical enterprise applications. In the worst case scenario, email servers have been known to crash from extreme workload.
By implementing Accellion secure file transfer, companies are able to offload file attachments from email servers preserving network performance and equally importantly enabling end users to exchange large files.
You can’t get there from here
Exchanging large files has become a core business process for most organizations, and saying “You can’t get there from here” is not an adequate answer to what to do with large files.
Email servers and client software are not designed to handle large files and sending and receiving email attachments is typically limited to files less than 5-10 MB in size. Accellion enables users, internal and external, to send large file attachments regardless of email attachment limits.
Accellion—no attachment limits
Accellion secure file transfer allows internal and external users to send and receive files and folders without adding IT administrative overhead or infrastructure burden. With Accellion, IT has a solution for how to enable users to send large file attachments without clogging email servers and slowing down the messaging infrastructure. End users love the solution too, since it uses a familiar email interface. Using Accellion end users still send an email, but instead of the file being attached and sent through the email system, the file is uploaded to an Accellion appliance. Recipients download the file by clicking on a secure link sent along with the email message.
