Fluxmail Cloud

Fluxmail Cloud lets agents and apps work with your Gmail, Outlook, and IMAP mailboxes. Connect your email provider, choose what each agent can access, and use hosted MCP or REST to search, read, draft, send, and organize mail.

You manage your account, mailbox connections, OAuth connections, and agent keys in the Cloud dashboard.

Get started

Follow the quickstart to set up Cloud with your coding agent or connect manually. Once you have a mailbox, choose your connection:

• Connect an agent over MCP with OAuth in ChatGPT, Claude, Codex, Claude Code, Muse, Hermes, Cursor, or another compatible client.
• Use the REST API from your application or a script.

Control access

Each OAuth connection or agent key has access to the mailboxes and operations you select. Approve each client separately so you can revoke access independently. Agent connections and permissions explains the available scopes and how provider consent differs from an agent's access.

Mail remains with your email provider. Cloud stores encrypted provider credentials, account information, OAuth grant and token records, key hashes, usage counters, audit metadata, and send-operation records. You can disconnect a mailbox or delete your Cloud account without deleting mail at your provider.

Current limits

Cloud supports Gmail through Google, Outlook through Microsoft, and other providers through IMAP and SMTP. Google and Microsoft connections depend on the Cloud deployment's provider configuration and your organization's access policy.

Cloud offers Pro and Business subscriptions, with a seven-day trial on a workspace's first subscription. Business owners can invite workspace members. Scheduled sends and remote configuration through the fluxmail CLI are not available. The separate Fluxmail Self-Hosted package has its own CLI, licenses, and keys.

See troubleshooting and limits for connection failures, quotas, and attachment sizes. Before sending mail, read sending and retries.

Documentation for agents

The setup instructions guide an agent through configuring a client and verifying access. Cloud docs as plain text contains every Cloud guide. Cloud also appears in the site's documentation index and full documentation.
