Run email warmup with Cursor

Yes — Cursor can set up, tune and monitor email warmup across your mailboxes in WarmySender, all in plain language, through the same 78-tool connection Claude, ChatGPT, Cursor, Codex, OpenClaw, and Hermes Agent share. You ask in Cursor’s chat panel, inside the editor. It never sends a message itself and can never raise a limit: it writes the campaign and hands it to WarmySender’s scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits no matter who is driving. Connecting and disconnecting accounts stays in the app.

Why Cursor for email warmup

You talk to Cursor in the chat panel of the editor you already work in, so outreach sits next to the code and files of the project. It connects with the one-click Add to Cursor button, or a small block in .cursor/mcp.json in your project root; sign in when Cursor asks. Warmup from Cursor is for people who set mailboxes up as part of a build: open the chat panel, turn warmup on for the new mailboxes, and check health from the same window you write code in.

What Cursor can and cannot do with email warmup

Every "can" below stands on a real tool in the WarmySender connection. Every "cannot" is not a setting — there is simply nothing an agent can call that does it.

Can / cannotWhat that means for email warmup
CanTurn warmup on for a connected mailbox and choose its strategy and target volume.
CanApply the same warmup settings across a whole set of mailboxes in one instruction.
CanList your mailboxes and report on each one’s health before you scale up sending.
CanRead how each mailbox’s reputation is building and today’s warmup volume.
CanMove warmed mailboxes onto steady maintenance so warmup keeps running quietly.
CannotSend the warmup mail itself — WarmySender produces and paces it on a ramp an agent cannot reach.
CannotMake warmup finish faster or skip a stage — the ramp advances on sending days, not on request.
CannotTurn warmup on for a mailbox that is not connected.
CannotConnect a mailbox or see a password — connecting stays in the app.
CannotRemove the small reference tag in warmup subjects that lets you filter warmup mail out of your inbox.

Connect Cursor to WarmySender

Cursor connects with one click from your browser, or one small file in your project — then you drive outreach from the editor you already work in.

Use the Add to Cursor button, or paste this into .cursor/mcp.json in your project root and sign in when Cursor asks.

File: .cursor/mcp.json

{
  "mcpServers": {
    "warmysender": {
      "url": "https://warmysender.com/mcp"
    }
  }
}

Add WarmySender to Cursor

Prefer a key? Create one under Settings › API Keys and choose exactly which permissions it carries, including read-only. With a key, the Cursor route is: Use the Add to Cursor button, or paste this into .cursor/mcp.json in your project root.

Both routes reach the same workspace and stay inside the same safe limits. Every agent's steps live on the AI Agents hub.

How a session goes in Cursor

  1. Open Cursor. Open the project that holds .cursor/mcp.json and open Cursor’s chat panel.
  2. Say what you want. In Cursor’s chat panel, inside the editor: "Turn warmup on for all twelve new mailboxes with the new-domain strategy."
  3. Check back whenever you like. From the same chat panel, ask: "How much warmup mail did the outreach@ mailbox send today, and is it arriving?"
  4. The scheduler does the sending. Cursor has only written the plan. WarmySender’s scheduler paces every warmup email inside safe limits and the gradual ramp, and keeps going after the editor is closed.

Things to say to Cursor

Safe by design — no matter who's driving

Cursor never sends a message itself and can never raise a limit. Creating or launching a campaign only writes it and hands it to WarmySender's scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits and a gradual ramp — the same protections that apply when a human clicks the buttons. Connecting and disconnecting accounts stays in the app. Account safety always wins.

Frequently asked questions

Can Cursor run email warmup across your mailboxes for me?

Yes. Connect Cursor to WarmySender and ask in plain language, in Cursor’s chat panel, inside the editor — it can set up, tune and monitor email warmup across your mailboxes. It never sends a message itself and can never raise a limit: it writes the campaign and hands it to WarmySender’s scheduler, which paces every email, LinkedIn, Instagram and WhatsApp action inside safe limits no matter who is driving. Connecting and disconnecting accounts stays in the app.

How do I connect Cursor to WarmySender?

Cursor connects with one click from your browser, or one small file in your project — then you drive outreach from the editor you already work in. Use the Add to Cursor button, or paste this into .cursor/mcp.json in your project root and sign in when Cursor asks. The block for .cursor/mcp.json is: { "mcpServers": { "warmysender": { "url": "https://warmysender.com/mcp" } } } — the server address is https://warmysender.com/mcp. The steps are on this page under "Connect Cursor", and the full install hub for every agent is at /ai-agents.

Can Cursor raise my email warmup limits?

No. Nothing an agent can call moves a limit — not the warmup ramp, a stage or the ceiling on a mailbox’s daily warmup volume. Cursor can read where you are against a limit and tell you when a pause lifts; WarmySender’s scheduler decides what actually goes out.

Can Cursor connect my mailbox?

No. Connecting and disconnecting accounts stays in the app on purpose — a credential should never pass through an agent or a chat log. Connect the mailbox once in WarmySender; after that Cursor can use it.

Can Cursor make warmup finish faster?

No. Warmup rises gradually on its own schedule and the ramp advances on sending days, so a mailbox that was disconnected for a while is simply a few sending days behind. If warmup slows for one mailbox it is usually a safeguard working — WarmySender eases that mailbox back on its own — and neither you nor an agent can lift that slowdown, because the slowdown is the fix.

What does the Add to Cursor button do for email warmup?

It opens Cursor and offers to add the WarmySender server — the same result as pasting the block on this page into .cursor/mcp.json (the server address is https://warmysender.com/mcp). Accept, sign in when Cursor asks, and the email warmup tools are available in the chat panel.

Should the WarmySender connection be per project or global in Cursor?

The block on this page goes in .cursor/mcp.json in the project root, so it travels with that project. Cursor also supports a global configuration file; either way the sign-in is the same and the safe limits are identical.

Does the Add to Cursor button use a sign-in or a key?

A sign-in: Cursor asks you to sign in to WarmySender the first time it reaches the server, so no key is written to .cursor/mcp.json. Prefer a key? Create one under Settings › API Keys and use the key form on the AI Agents hub.
