Mailroom is an app tightly integrated with Slack that lets your team ship packages with UPS and FedEx — no shipping expertise required. Just type /ship
Why Mailroom
Your team ships faster. Your company spends less. You sleep better.
Save 20–40% on shipping
Mailroom's cost engine compares rates across carriers in real time and picks the cheapest option that still arrives on time. Stop overpaying for air when ground gets there just as fast.
Ship in 60 seconds from Slack
No new tools to learn. No emails. No spreadsheets. Your team types /ship, follows a guided flow, and gets a label in their DM. That's it.
Nothing to lose. Literally.
Mailroom is free. You ship on your own carrier accounts with no markup and no per-label fees. Don't have an account? Use ours to get started. You only pay what the carrier charges.
Features
Everything your team needs to ship smarter
Access control, cost optimization, insurance, and workflow automation — all in one platform.
Access Control & Permissions
Give your team shipping access without sharing credentials. Set spend limits, carrier restrictions, and approval thresholds per user — with a full audit trail of every shipment.
Intelligent Cost Optimization
Employees enter the delivery deadline, not the service level. Mailroom compares rates across carriers and picks the cheapest option that still arrives on time.
Insurance & Managed Claims
Package insurance at rates below what carriers charge directly. When something goes wrong, Mailroom handles the entire claims process — from filing to resolution.
Slack-Native Workflow
Request shipments, approve them, and get tracking updates — all without leaving Slack. No new tools to learn, no context switching.
Smart Address Book
Every recipient and address is saved automatically. Frequent destinations become single-click. New team members inherit the same speed from day one.
AI Package Estimation
Describe what you're shipping and Mailroom suggests weight, dimensions, and box size. No measuring tape required. Fewer carrier surcharges.
