Run email verification with Cursor

Yes — Cursor can verify email addresses and turn the clean ones into a campaign 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 verification

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. Verification from Cursor is a good match because the list is usually a file already open in the editor: ask the chat panel to verify it, wait for the batch, and turn the safe addresses into a prospect list without leaving the project.

What Cursor can and cannot do with email verification

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 verification
CanCheck a single address on the spot — safe to send to, risky, or not deliverable.
CanSubmit a whole list and follow the results as they come in.
CanCheck how much of your allowance is left before committing a big list.
CanStop a batch that is still running.
CanTurn the confirmed addresses into a prospect list, ready to enroll.
CanBuild and start the campaign around the clean list in the same conversation.
CannotSend to anyone — building the campaign only hands it to WarmySender’s scheduler.
CannotVerify faster than the app or raise your allowance — it shares the same monthly allowance and pacing.
CannotBuy credits — anything touching billing stays with you in the app.
CannotFind an address you do not have — verification confirms addresses, it does not discover them.
CannotConnect or disconnect a mailbox.

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: "How much verification allowance do I have left this month?"
  3. Check back whenever you like. From the same chat panel, ask: "How much verification allowance do I have left this month?"
  4. The scheduler does the sending. Cursor has only written the plan. WarmySender’s scheduler paces every verification 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 verify my email list for me?

Yes. Connect Cursor to WarmySender and ask in plain language, in Cursor’s chat panel, inside the editor — it can verify email addresses and turn the clean ones into a campaign. 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 verification limits?

No. Nothing an agent can call moves a limit — not your monthly verification allowance or the pace at which a batch is checked. 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.

How is my allowance spent when Cursor verifies a list?

Exactly as in the app: the agent shares the same monthly allowance and credits and cannot verify any faster. You are only charged for answers — one credit per confirmed result, nothing for one that cannot be confirmed either way — and credits never expire.

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

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 verification 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.
