Gmail, iCloud and IMAP inboxes together in Claude and ChatGPT

What the built-in connectors cover

Claude's Gmail connector covers Google accounts, and support for several accounts is rolling out progressively (November 2026): check your Claude settings first. ChatGPT supports several Gmail accounts natively.

Claude has no built-in connector for iCloud Mail or IMAP mailboxes on your own domain, and neither assistant connects Google Chat or Telegram, so one question across all of them is not possible natively. That is the gap a connector like Fezola fills.

Your options

• Use the built-in Gmail connector: free, but Google accounts only.
• Forward a second Gmail into your main one: simple, but older mail stays behind, and replies go out from your main address unless you set up “Send mail as”.
• Run an open-source multi-account Gmail MCP server yourself: flexible, but it needs your own Google Cloud project, and it usually runs only in Claude Desktop or Claude Code.
• Use a hosted connector such as Fezola: nothing to install, works on claude.ai, the desktop app and mobile, and also in ChatGPT.

How Fezola keeps your accounts apart

• Every search result carries its account name and address, so Claude can tell you which inbox each email came from.
• You can search all accounts at once or a single one.
• A reply is drafted in the mailbox that received the email, with that address as the sender. Nothing is sent: you review the draft and send it from Gmail.

Step by step

1. 1

   Create a Fezola account

   Sign up for free. The Free plan includes 2 sources, so two Gmail accounts fit without paying.

2. 2

   Connect your first Gmail account

   In Sources, add a mailbox, choose Gmail and click “Continue with Google”. Give it a short name such as Personal.

3. 3

   Connect your other Gmail accounts

   Repeat for each account (Work, Side project), signing in with the matching Google account. If Google sign-in is unavailable, use a Gmail app password instead: it requires 2-Step Verification on that Google account.

4. 4

   Add Fezola to Claude

   In Claude, open Customize, then Connectors, click + Add, then Add custom connector. Name it Fezola and paste https://api.fezola.com/mcp. On Team and Enterprise plans, an Owner adds it once in Organization settings, Connectors.

5. 5

   Approve access

   Click Connect. Fezola opens a sign-in and consent screen listing the sources Claude will access. Once you accept, Fezola works on claude.ai, in the desktop app and on mobile.

6. 6

   Ask across your accounts

   Try: “What came in across my Gmail accounts today, and what still needs an answer?”, “Find the contract PDF sent last week, in any account, and summarize it”, or “Draft a reply to that email from my work address.”

Why Fezola

• All your Gmail accounts behind one connector, plus iCloud, any IMAP mailbox, Google Chat and Telegram.
• Each result names its account; replies are drafted in the mailbox that received the email.
• Reads attachments: PDF, Word, text files and images.
• Works in Claude, ChatGPT, Perplexity and other MCP clients.
• Messages are read live and never stored; tokens and passwords are encrypted.
