MCP server and API
Set up cold email from Claude, Cursor or Codex
One command connects your AI assistant to Outreach2day: it checks domains, quotes mailboxes, you approve and pay on Stripe, it sets up DNS, warm-up and campaigns.
Three steps, one command
- Run the command. It finds the AI clients on your computer and adds the Outreach2day server
- Sign in from your client. The first time it connects, the client opens an Outreach2day sign-in page. Turn on Prepare orders there so the assistant can quote orders. No API key to copy
- Ask your assistant. Start with “Check my Outreach2day account status”. It quotes every order; you approve and pay on Stripe
curl -fsSL https://outreach2day.com/install | shirm https://outreach2day.com/install.ps1 | iexIt adds the server by URL to Claude Code, Cursor, VS Code, Windsurf, Gemini CLI and Codex, and prints the connector steps for Claude Desktop, after a backup of each config. No API key: each client asks you to sign in on first use. View the script
Add it by hand: Claude Code, Claude Desktop

Our reps spend less time prospecting and writing emails, and more time following up on the inbound requests that the tens of thousands of emails we’re able to send now generate. Special shoutout to Max and the team who were incredibly helpful and knowledgeable during the migration.”

$2.50 per mailbox a month, including warm-up, the sending engine and the analytics. The minimum is 12 mailboxes, so the smallest bill is $30 a month. You pay monthly by card.
Domains are the one other cost, paid per year: $13 for a .com, $5 for a .info. A card processing fee (2.9% + $0.30) is added at checkout, on new domains and the first month of mailboxes; monthly renewals are $2.50 per mailbox. For example, 12 mailboxes and one .com come to $44.60 at checkout: $30 for the first month, $13 for the domain and a $1.60 fee. There is no platform fee, and workspaces and team members are free.
$2.50 is the list price. Volume discounts are available for large orders: book a call or contact sales for bulk mailbox pricing.
Everything you need to send cold email, except domains:
- The mailbox itself, with SMTP and IMAP access.
- SPF, DKIM, DMARC and a redirect to your website, set up automatically.
- Warm-up for as long as you keep the mailbox: 25+ warm-up emails a day to Google recipients, 25 to Outlook and 25 to other providers, 75+ a day in total.
- The sending engine: campaigns, multi-step sequences, schedules and follow-ups.
- One inbox for the replies from all your mailboxes.
- Analytics for every mailbox: warm-up inbox, spam and bounce rate, sends by recipient provider, and replies sorted by type.
- Google and Outlook placement tests.
- SSL domain masking and link protection.
- Sync to Instantly and Smartlead, CSV export for other tools, and the API.
No. They are standard SMTP/IMAP mailboxes on your domains. You can send from them with our sending engine or with any tool that connects over SMTP and IMAP, including Instantly and Smartlead.
First cold emails from day 14, full volume from day 21:
- Day 1: new mailboxes are ready within 24 hours. For your own domains, the nameserver change takes 24–48 hours.
- Days 1–14: warm-up only.
- From day 14: start cold email at a low volume.
- Day 21: full volume.
Keep warm-up running while you send.
Yes. Connect Instantly or Smartlead with an API key, and we add the mailboxes to your account there.
For other tools, download a CSV in the tool's own import format: SalesHandy, Reply.io, Apollo, Snov.io, Mailshake, ReachInbox, PlusVibe, Luna, Nureply, Coldy, MailToaster, EmailBison.
For anything else, the CSV has the SMTP/IMAP logins of every mailbox, and our API returns the same.
Or send from Outreach2day itself: campaigns, sequences and the reply inbox are built in.
Yes. Give each client or team its own workspace, with its own mailboxes and domains. Workspaces and team members are free: you pay only for mailboxes and domains.
We recommend up to 25 cold emails per mailbox a day, excluding warm-up. Above that, mailboxes and domains burn out sooner.
Put up to 5 mailboxes on one domain. For 1,000 emails a day you need 40 mailboxes ($100 a month) on 8 domains ($104 a year as .com).
Replies land in the mailbox that sent the email. In Outreach2day you read and answer the replies from all your mailboxes in one inbox.
If you send through Instantly or Smartlead instead, the replies show up there too, because those tools read the mailboxes over IMAP.
Yes. Point the nameservers of a domain you own to ours, and we set up SPF, DKIM, DMARC and a redirect to your website.
Domains you buy in the app are registered for 1 year with your details as the registrant, so they are yours. Support can move them to your own Namecheap account. Renewal is not automatic: when a domain expires, its mailboxes stop working.
Don't send cold email from your main company domain.
There is no free trial and no contract. You pay month to month and can cancel any time in the in-app chat or at support@outreach2day.com.
Mailboxes you add mid-month are charged right away, prorated. Removing mailboxes gives no credit for the current month.
The mailboxes are deleted and can't be restored, so move your campaigns off them first. You are not charged after the month you have paid for.
The domains stay yours. Support can move them to your Namecheap account; after that you set up the DNS records and the redirect yourself.
You replace the domain and keep paying the same for mailboxes. Billing is per mailbox slot: delete the mailboxes on the burned domain and create new ones on a fresh domain in the same slots. The new domain costs the usual price, and the new mailboxes need warm-up.
Before you buy new domains, try new copy. In our data, fresh domains sending the same copy from the same servers did no better than the old ones. Rewritten copy did.
No. Placement depends on your list, your copy and the recipient's email provider. Outreach2day measures it for every mailbox.
Each mailbox shows its warm-up inbox, spam and bounce rate, and placement tests show which Google and Outlook seed inboxes received your email and which sent it to spam.
Since 2024, 3,600+ teams have used Outreach2day, including outbound agencies, a fintech company and B2B sales teams. Together they send 5M+ cold emails a day through the platform.
.com. A .info costs $5 a year instead of $13; give it two extra weeks of warm-up.
In our tests with finance and lending copy, .info domains did 3.5× worse on Outlook than .co domains. With neutral copy we saw no difference.
Yes, on every account at no extra cost. It covers workspaces, domains (including purchase and redirects), mailboxes, warm-up and reply threads.
Docs are at dev.outreach2day.com. The limits are 10 requests a second, 300 a minute, 1,000 an hour and 10,000 a day, per user and per workspace.
Write to us in the in-app chat or at support@outreach2day.com. For deliverability questions, such as how many mailboxes and domains you need or how much to send a day, book a call with our deliverability team.
First cold emails on day 14, full volume on day 21
Add domains, create mailboxes and turn on warm-up. You see every mailbox's warm-up numbers from day one.
