Cold email infrastructure
Done-for-you cold email infrastructure that lands in the inbox

Pricing

Each domain you bring becomes 100 Microsoft 365 Outlook inboxes for cold email. The more domains in one order, the lower the per-inbox cost. Domain registration is separate (about $10-15/year at any registrar like Porkbun, Namecheap, or GoDaddy).

Questions
Frequently asked.
Do I need to buy a domain separately?+
Yes. You register the domain at any registrar (Porkbun, Namecheap, GoDaddy, etc.) for about $10-15/year. We then set up 100 Microsoft 365 Outlook inboxes on that domain. You can also order bundles for multiple domains in a single order.
What's included with each domain?+
For every domain you own, we provision 100 Microsoft 365 Outlook inboxes, full DNS configuration including SPF, DKIM, and DMARC records, mailbox warm-up, and ongoing deliverability monitoring. The domain itself you register separately at any registrar.
How long does setup take?+
Most orders are fully configured and delivered to your dashboard within 72 hours of payment. Larger orders of 50 or more domains may take up to 6 days.
What sending platforms do you support?+
We integrate with Email Bison, Smartlead, Instantly, Lemlist, and Manyreach. Choose your platform at checkout and we will load the inboxes for you. If you use something else, pick the self-serve option and we deliver inbox details as a CSV.
What if a domain gets burned?+
If a domain reaches a state where deliverability cannot be recovered, we replace it at no additional cost. Replacement requests are handled through your dashboard.
Can I cancel anytime?+
Yes. Subscriptions are monthly and can be cancelled directly from your dashboard. Cancellation takes effect at the end of the current billing period.
Do I need to give you my sending platform login?+
Only if you want us to load the inboxes for you. The self-serve option avoids sharing credentials entirely. You receive a CSV with all inbox details and configure your sending tool yourself.
Can I customize the email names on each domain?+
Yes. For each domain in your order, choose between random names (we generate 100), your own list of 100, an auto-distributed set (e.g., 4 names spread across 100 inboxes), or a custom distribution (you specify names and how many of each).
