Emailgents vs Composio for email access
A developer toolkit for hundreds of apps; email is one of them.
Composio gives developers managed authentication and tool definitions for a very large catalogue of SaaS apps. Gmail and Outlook are two toolkits among them, delivered through SDKs and a hosted MCP endpoint.
It is a strong choice when you are building a product that needs many integrations. For a person who wants their own agent to read their own mail, it means creating a developer account, wiring up toolkits and reasoning about scopes yourself. iCloud and generic IMAP are not in the catalogue.
Emailgents does one job end to end: connect any mailbox, keep an index, expose read-only tools and log every access. No code, no toolkit configuration.
