Free, read-only, and no sign-in. WarmInboxes applied to Google’s Connected Apps program on 10 November 2026; it is not listed yet. The program is in preview. Until it is listed in Gemini, the same free tools run in ChatGPT, Claude and Cursor. ## What it does - Check a sending domain: SPF, DKIM, DMARC, MX, blocklists and domain age, with an A-F grade. - Read bounce messages and email headers and say what they mean. - Check cold email copy for spam triggers before it is sent. - Plan how many inboxes and domains a daily volume needs, and how to rotate them. - Explain how to connect a WarmInboxes account when you are ready to order or manage inboxes. It reports what each check returned and names the tool that ran it. A check that could not run is reported as not run, never as a pass. It does not query the Spamhaus DBL, does not give reputation scores (mailbox providers keep those private), and cannot send email, change DNS or touch anyone’s inboxes. ## Try it Type @WarmInboxes in Gemini, or name it in your request: - WarmInboxes, is acme.com set up correctly to send cold email? - WarmInboxes, why are these emails bouncing? [paste the bounces] - How many inboxes do I need for 3,000 cold emails a day? Ask WarmInboxes. - WarmInboxes, how do I connect my WarmInboxes account? ## Your data, disconnecting and deleting WarmInboxes in Gemini has no sign-in. We receive no Google account details, name or email address, and the app cannot see or change a WarmInboxes account. - What Gemini sends for a check (a domain, pasted headers, bounces or copy) is processed in memory to produce the answer and returned. It is not stored and its contents are not logged. - A daily limit counts the distinct domains checked against the IP address the request comes from. Those records are deleted within two days. - Each tool call records an anonymous usage event (which tool, the kind of client, a coarse outcome) with no domain, nothing you pasted and no identifier, deleted after 90 days. - When it sizes a fleet, the plan is saved at its own link for 30 days, holding counts and prices only, so you can open it again. To disconnect: in Gemini, open Settings & help, then Connected apps, and disconnect WarmInboxes. Nothing is stored against you, so there is nothing to delete; if you want us to confirm that or have a question, contact us through the [privacy policy](https://warminboxes.com/privacy), which covers this app in its free tools section. ## When you’re ready for your own account WarmInboxes in Gemini runs the free, read-only tools: domain checks, bounce and header reading, copy checks and fleet planning. It has no sign-in, so it cannot see or change a WarmInboxes account, place an order or touch anyone's inboxes. Everything below happens outside this chat, in the WarmInboxes app or in a client that can hold an API key. ### Order inboxes for the first time - Open the WarmInboxes app at https://app.warminboxes.com and create an account. - If a planning result here gave you a saved plan link, open it: its order link carries the plan into the app, so the counts are filled in. - Place the order in the app. You pay on a payment page you open yourself; nothing is charged from a chat. - Inboxes are delivered within 48 to 72 hours of payment. Prewarmed ones send on delivery; fresh ones warm for 14 to 21 days first. ### Check or change an account you already have - Sign in at https://app.warminboxes.com. - The dashboard shows every order, its domains and its build state. A domain marked waiting on you needs its nameservers pointed where the app shows. - Domain forwarding, client workspaces, inbox names and exports into Instantly, Smartlead, PlusVibe or Email Bison are all in the app. - Cancellation is by domain: a domain is cancelled with all of its inboxes. ### Let an AI assistant work your account - Use a client that can send an API key with each request: Claude Code, Cursor, Claude Desktop or VS Code, or the wib command line. Gemini cannot hold a WarmInboxes key yet. - In the app, open Settings, then API keys (account owner only). Pick only the scopes you need: read for reporting, write for exports and changes, orders:place only if the assistant should place orders. - Turn on Test key first. A test key runs every tool against a sandbox copy of your account: nothing is charged, built or changed. - Add WarmInboxes Infrastructure MCP (https://api.warminboxes.com/mcp) to your client with the key as a bearer token, in your own terminal or config file. In Claude Code: claude mcp add --transport http warminboxes-infrastructure https://api.warminboxes.com/mcp --header "Authorization: Bearer wib_your_key_here" - Before any order, the assistant previews it and shows you the price; it places the order only on your yes. ### Try ordering without spending anything - Make a test key in the app (Settings, then API keys, with Test key on). - Connect it as above. Every answer comes from a sandbox with five example orders and a test card; time moves, so a test order builds in minutes. - Swap in a live key when the flow works. ### Keeping your account safe - Never paste an API key, a sequencer password or a registrar password into a chat. Keys go in your terminal, your client's config or the app. - If a key ever ends up in a chat, revoke it in the app (Settings, then API keys) and make a new one. Revoking takes effect on the next request. - Anything that charges a card is previewed and shown to you first. The full reference for WarmInboxes Infrastructure MCP and the API is at [docs.warminboxes.com](https://docs.warminboxes.com), and the setup guide at [Developers](https://warminboxes.com/developers). ## For developers The Gemini app is a Streamable HTTP MCP server at https://warminboxes.com/mcp/google/v1, no authentication: fifteen read-only tools from the free WarmInboxes tools, plus the account guide. Every free tool is on the full server at [WarmInboxes Free MCP](https://warminboxes.com/plugins/free-mcp). ## Prewarmed & Fresh Inboxes Google, Microsoft 365 and Azure inboxes with free prewarmed domains and DNS configured before you log in. Prewarmed inboxes send the day they land; every order is delivered within 48 to 72 hours.
