Claude has a built-in Gmail connector that can search, read, draft, send, reply to, and forward email and manage labels. By default it asks for approval before each send. If that covers your needs, it needs no other account or setup. Fluxmail Cloud is in Claude's connector directory, and self-hosted Fluxmail runs on your own machine. Either one adds attachment downloads, more providers, and access from other agents and apps. Self-hosted Fluxmail can also schedule sends.
This comparison covers Fluxmail Cloud, which we host, and self-hosted Fluxmail, which you run. Cloud doesn’t keep a copy of your mail.
Choose Fluxmail when the workflow must read attachment contents, cross providers, serve clients beyond Claude, or schedule mail with self-hosted Fluxmail. Choose Claude Gmail when you only need Gmail inside Claude and want nothing else to set up.

A closer look
What Fluxmail adds to Claude's Gmail tools
Claude's Gmail connector can search and read email, create drafts, send, reply to, and forward messages, manage labels, and return attachment metadata. It asks for approval before each send by default.
Fluxmail adds attachment downloads, along with tools for read state, stars, archive, trash, and folders. These tools are available through MCP and REST. Self-hosted Fluxmail also schedules delivery and has a CLI.
Fluxmail works across more providers and interfaces
Both products handle everyday email work such as finding messages, reading threads, drafting and sending replies, and managing labels. Claude's Gmail connector keeps those workflows inside Claude and works with Gmail.
Fluxmail makes the same workflows available through MCP and REST, with one interface for Gmail, Outlook, Exchange, and IMAP. The same agent or backend can work across providers without being tied to Claude or Gmail.
Which services handle your mail
With Claude's built-in connector, the connection and email requests run through services operated by Anthropic and Google. Access is governed by Claude organization controls and Google OAuth.
With Fluxmail Cloud, requests run through Fluxmail and your email provider, and Cloud doesn't store messages or attachments. Self-hosted Fluxmail takes Fluxmail's servers out of the path: credentials and the database stay on a machine you choose. In both cases Claude, like any MCP client, may send the email it reads to its model provider, and that provider's data policies apply.
Which should you choose?
Best choice
Fluxmail
The workflow must read or download attachment content.
Mailboxes include Outlook, Exchange, or IMAP.
Email access must work in clients beyond Claude.
You need server-side profiles and mailbox allowlists.
The agent needs to schedule email for later delivery, which self-hosted Fluxmail supports.
Claude Gmail
You only need Gmail inside Claude or Claude Desktop.
You want a free connector with nothing else to set up.
Common questions
Can Claude send Gmail messages with its connector?
Yes. Claude can send, reply to, and forward Gmail messages, and by default it asks for approval before each one. Team and Enterprise owners can let members skip that approval. Fluxmail can also send when the connection has mail.send permission, and self-hosted Fluxmail can schedule messages for later delivery.
Can Claude read Gmail attachments?
The built-in Gmail connector exposes attachment metadata, not the file content. Fluxmail can download attachment content as an MCP resource for a compatible client.
Can Fluxmail be used with Claude?
Yes. Fluxmail Cloud is in Claude's connector directory: open Customize > Connectors, search for Fluxmail, and approve access. Claude Code can add https://cloud.fluxmail.ai/mcp from the terminal. Self-hosted Fluxmail works with Claude Desktop over stdio, or as a remote connector over Streamable HTTP.
