💡 Quick Savings Math
A company with 25 users upgrading to higher tier enterprise plans just to solve mailbox storage bloat spends $6,900/year extra. With Mailarch Growth at $199/year, you eliminate storage ceilings across all 25 mailboxes for a fraction of a single license upgrade — while keeping desktop Outlook running fast.
