Claude email integration: connect Gmail, iCloud and any mailbox to Claude

Short answer: there are two ways to connect your email to Claude. For one Gmail account, turn on Claude's built-in Gmail connector. For iCloud, your own domain, several accounts or a mix, add a custom connector such as Fezola, which brings every mailbox behind one URL. Facts about Claude's own connector come from Anthropic's help center, checked on 9 November 2026: they change fast, so check the current page.

Option 1: Claude's built-in Gmail connector

According to Anthropic's help article on Google Workspace connectors, the Gmail connector is available on Claude and Claude Desktop. You turn it on in Customize, Connectors, and sign in to Google. It can search and read email, draft, and send, reply to and forward with your approval by default. It cannot read the content of attachments. This is the shortest setup if you have one Google account. For the full comparison of Gmail routes, read Gmail MCP server for Claude: official, open source or hosted.

Option 2: a custom connector for every mailbox

A custom connector is a remote MCP server that you add by pasting a URL. Fezola is one: it connects Gmail, Outlook.com, iCloud and any IMAP mailbox, and Claude then sees them together.
