Can Cursor run cold email through MCP?

Yes, in early access. One entry in ~/.cursor/mcp.json gives the Cursor agent tools for domains, mailboxes, warm-up, campaigns and replies; you pay each order on Stripe.

Status: early access · Updated 28 September 2026

How it works

Cold email in Cursor, step by step

  1. 1

    Add one entry

    Put the server URL and your key in ~/.cursor/mcp.json or the project's .cursor/mcp.json.

  2. 2

    Work from your files

    The agent reads your lead lists and copy in the repo and imports them into a draft campaign.

  3. 3

    Order what is missing

    Short on mailboxes? The agent quotes more, you pay on Stripe, and it tracks setup and warm-up.

  4. 4

    Ship and monitor

    After warm-up the agent launches and pulls replies and per-mailbox stats back into your workspace.

Prompts

Things to ask Cursor

Plain language is enough. The agent picks the tools and asks before anything costs money.

  • Read leads/q4.csv, drop rows without a work email, and import the rest into the Q4 campaign.
  • Put the copy from copy/sequence.md into a 3-step campaign and check it for spam words.
  • How many mailboxes are warm, and how many emails a day can they send?
  • Quote 8 more mailboxes on our existing domains.
  • Write today's replies to replies.md, grouped by campaign.

Tools

23 tools, from domains to replies

Tools ship to early-access workspaces first. Today the REST API covers workspaces, domain checks and warm-up status.

Guardrails

Cursor quotes. You pay.

Money moves only on a Stripe page you open. Cursor can prepare an order, never complete one.

Cursor can

  • Check domains, quote an order and send you the Stripe link
  • Connect domains you already own and give you the DNS records
  • Start warm-up and tell you when each mailbox is ready
  • Write and check the sequence, import contacts, launch after warm-up
  • Read replies and per-mailbox stats, pause a campaign that trips bounce limits
  • Export warm mailboxes to Instantly or Smartlead after you confirm

Cursor cannot

  • Charge a card: every payment happens on a Stripe page you open
  • Launch a campaign before warm-up is done and the preflight check passes
  • Delete domains or mailboxes, cancel your plan or rotate passwords
  • Show mailbox passwords, SMTP/IMAP credentials or API keys in the chat
  • Order more than the first-order and daily spend limits of your workspace

FAQ

Questions

Or talk to the team

Where does the Outreach2day key go in Cursor?

In the headers of the server entry in mcp.json. Use the global file for all projects, or .cursor/mcp.json in a project and keep that file out of git.

Can the Cursor agent send email by itself?

It can launch a campaign only after warm-up is done and the preflight check passes, and launch asks for confirmation. It cannot send one-off emails outside a campaign.

Can Cursor spend money on my behalf?

No. Cursor can ask for a quote and hand you a Stripe checkout link. You pay on the Stripe page yourself. Quotes are priced by Outreach2day, and new workspaces have first-order and daily spend limits.

Is the Outreach2day MCP server available now?

In early access. Book a call and we add your workspace to the first group. The REST API is open to every account today: create a key in the app and call it from any script or agent.

What does it cost?

The MCP server comes with your Outreach2day account. You pay for what the agent orders: $2.50 per mailbox a month, domains billed yearly, both shown in the quote before you pay.

Which tools does the server have?

Tools for pricing and account status, domains, orders and Stripe checkout, mailboxes and warm-up, campaigns, replies and stats, and export to Instantly or Smartlead. The full list is on this page.

Can I use domains I already own?

Yes. The agent connects them and returns the DNS records to set at your registrar. Connecting your own domains is free.

How long until new mailboxes can send?

About 14 days of warm-up. The agent reports each mailbox's warm-up stage and ready date, and launch is refused until warm-up is done.

Can I keep sending from Instantly or Smartlead?

Yes. The agent exports warm mailboxes to your Instantly or Smartlead workspace after you confirm, and you keep your sequences there.

Does Cursor see my mailbox passwords?

No. No tool returns passwords, SMTP or IMAP credentials, or API keys. Export to a sequencer is the only step that moves credentials, and it needs your confirmation.

What happens if part of an order fails?

The order shows which domain or mailbox failed, with a link to support. Our team retries or refunds that item.
