Decision matrix
Which one is right for you?
Choose CME if…
- ›You're an end-user — you want Claude/Cursor/ChatGPT operating your own inbox.
- ›You need email beyond Gmail and Outlook (iCloud, Yahoo, Fastmail, Proton, AOL, Zoho, IMAP).
- ›You want depth: 208 email tools, sweep over 500K messages, predictable flat pricing.
Choose Arcade.dev if…
- ›You're a developer building an agent product that needs OAuth + token vaulting.
- ›You need self-hosted or dedicated-tenant deployment with audit logs, RBAC, SSO.
- ›You want one runtime spanning Gmail, Slack, Salesforce, GitHub, Notion etc.
Choose both if…
- ›Developer using Arcade for the cross-SaaS catalog AND CME as the email plane.
- ›You want broad tool coverage from Arcade plus richer email semantics from CME.
