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: 203 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.

If you're building an agent product that needs OAuth across many SaaS, Arcade is the right shape. If you want your own inbox in your AI this afternoon, that shape is overkill.
