Cloud or Self-Hosted
Both give agents the same permissions. The main difference is who runs the server.
| Feature | Cloud | Self-Hosted |
|---|---|---|
| Who runs it | Fluxmail runs it for you. Nothing to install. | You run it on your computer, a server, or Docker. |
| Setup | Paste one prompt into your agent, or add the server URL by hand. | Install the npm package or Docker image, then add mailboxes. |
| How agents connect | MCP over HTTPS with OAuth, or REST with a scoped key. | MCP over stdio or HTTP, REST, and a CLI. |
| Supported agents | Any MCP client that supports remote servers, including ChatGPT and Claude on the web. | Any MCP client. ChatGPT and Claude on the web need your server on a public HTTPS address. |
| Provider credentials | Encrypted in Fluxmail Cloud. | Encrypted in a local SQLite database. |
| Your mail | Passes through Fluxmail between your provider and your agent. Cloud doesn’t keep a copy. | Stays with your provider and never passes through Fluxmail. |
Frequently asked questions
Self-hosted plans license the Fluxmail package you run on your own machine or server. With a Cloud plan you pay for the hosted service, so there's nothing to install or run. They're billed separately, and a self-hosted license doesn't apply to Cloud.
A mailbox is one connected Gmail, Outlook, or IMAP account. A member is a person in your Cloud workspace. Pro includes 1 member and 10 mailboxes. Business includes 20 mailboxes for each member you buy, pooled across the workspace, so a plan for 2 members allows 40.
A new Cloud account gets a 7-day trial of Pro, billed monthly, when it first signs in. You don't need a card to start it, and you can switch to Business or annual billing from Billing during the trial. To keep the plan, add a card in Manage billing before the trial ends, and Stripe charges for the plan when the trial ends unless you cancel. Without a card, the subscription ends with the trial. A workspace that has already had a subscription doesn't get another trial.
Open Billing in the Cloud dashboard. Pick the other plan or a different member count, and Stripe shows the charges before you confirm. Use Manage billing there to update your card, view invoices, or cancel. Only the workspace owner can change billing.
Cloud won't connect a mailbox beyond your plan's limit. If you switch to a smaller plan or buy fewer members, the mailboxes you connected first keep access, up to the new limit.
If a renewal payment fails, access continues for 7 days. If the first charge after a trial fails, access stops right away. Once access stops, agents can't reach your mail until billing is fixed, but you can still sign in to the dashboard. Cloud removes stored mailbox credentials 30 days after access is suspended. Your mail stays with your provider.
No. Cloud has no monthly usage allowances or overage charges. API calls and new send attempts have hourly limits.
