Corel WinZip Courier 10 — Volume License 2,000–4,999 | Email Compression, Attachment Policy

Keep corporate mail infrastructure available and predictable by reducing attachment size and enforcing compression policies at the edge. WinZip Courier 10 automates compression of outgoing attachments so large files do not exceed recipient or gateway limits, reducing mailbox storage and transport penalties. Sold as a volume license for 2,000–4,999 seats, Courier 10 is positioned for large enterprise rollouts where centralized policy, predictable licensing and mailbox storage savings justify the investment over point solutions. It integrates with enterprise mail clients and gateways to apply compression rules, provide end-user prompts and preserve archive integrity. For IT procurement, Courier 10 reduces help-desk incidents caused by undeliverable attachments and lowers archive retention costs through systematic size reduction of outbound mail.
