# Infrastructure recipes

What to actually buy for a given sending volume. Each one is a fixed plan with the inbox count, domain count and monthly cost worked out — not a calculator to operate.

Every figure comes from the same planner behind [the calculator](https://warminboxes.com/calculator) and the plan_infrastructure API, and the build fails if a page and that planner disagree. None of the plans reserves spare capacity beyond rounding up.

## The recipes

One scenario each, fully worked.

- [500 cold emails a day, Google-heavy list](https://warminboxes.com/recipes/500-emails-a-day) — 34 inboxes across 12 domains, $272 a month. The smallest fleet worth building properly: one pool, Google to Google, no rotation needed.

- [1,000 cold emails a day, mixed Google and Microsoft list](https://warminboxes.com/recipes/1000-emails-a-day) — 219 inboxes across 17 domains, $490 a month. The volume where splitting the fleet starts to pay: a Google pool and an Azure pool, matched to the recipients.

- [5,000 cold emails a day, agency setup](https://warminboxes.com/recipes/5000-emails-a-day) — 1,200 inboxes across 77 domains, $2,290 a month. Agency scale across two pools, where the domain count becomes the thing you manage.

- [1,000 a day to a Microsoft-heavy list](https://warminboxes.com/recipes/microsoft-heavy-list) — 370 inboxes across 11 domains, $436 a month. When your prospects are enterprise, the fleet inverts: Azure carries most of it.

- [Sending within the week, prewarmed](https://warminboxes.com/recipes/launching-this-week) — 219 inboxes across 17 domains, $490 a month. The fastest route to a working fleet, and what "prewarmed" does and does not remove.

- [1,000 a day on fresh branded domains, 21-day runway](https://warminboxes.com/recipes/fresh-domains-21-days) — 67 inboxes across 23 domains, $235 a month. Your own domains, warmed properly, and the three weeks that buys you.
