Can Claude run cold email through MCP?

Yes, in early access. Claude Code and Claude Desktop connect with an API key; Claude checks domains, quotes mailboxes, runs warm-up, launches campaigns and reads replies while you pay each order on Stripe.

Status: early access · Updated 28 September 2026

How it works

Cold email in Claude, step by step

  1. 1

    Plan the setup

    Tell Claude your domain and daily volume. It checks free names, sizes domains and mailboxes, and asks for a quote.

  2. 2

    Approve and pay

    Claude shows the quote and waits for your yes. You pay on the Stripe page it links; Claude never touches the card.

  3. 3

    Warm up

    Claude follows the order through DNS and mailbox creation, starts warm-up and reports each mailbox's inbox rate.

  4. 4

    Launch and read replies

    When warm-up is done Claude attaches the mailboxes, runs the preflight check, launches, and summarizes replies when you ask.

Prompts

Things to ask Claude

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

  • Set up cold email for acme.com: 3 domains, 12 mailboxes. Quote it and send me the payment link.
  • Connect acme-mail.com, which I already own, and give me the DNS records to set.
  • Draft a 4-step sequence for agency owners, check it for spam words, and keep it as a draft.
  • Export the warm mailboxes on tryacme.com to our Smartlead workspace.
  • Summarize replies from the last 24 hours and list the ones that ask for a call.
  • Pause any campaign where a mailbox's bounce rate is above 3%.

Guardrails

Claude quotes. You pay.

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

Claude 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

Claude 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

Which Claude apps can connect to the Outreach2day MCP server?

The first release supports Claude Code with your API key in a header and Claude Desktop through the mcp-remote bridge in claude_desktop_config.json. claude.ai custom connectors need OAuth sign-in, which ships after early access.

Does Claude need to run the whole setup in one chat?

No. Every call returns the current state and the next step, so you can come back days later and ask Claude where the order or the warm-up stands.

Can Claude spend money on my behalf?

No. Claude 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 Claude 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.
