New Domain Provisioning SOP: From Purchase to First Cold Email (Step by Step)

Most burned domains were burned in the first two weeks — not by bad copy, but by skipped setup steps and premature volume. This SOP is the full provisioning sequence we recommend for every new cold email domain. Follow it in order; the ordering matters.

Phase 1: Domain purchase (Day 0)

• Buy a variation of your main domain, never send cold email from the primary. getcompany.com, trycompany.com, company.io are standard patterns.
• Stick to .com where possible. Exotic TLDs (.xyz, .top, .click) carry baseline spam suspicion.
• Check the domain's history before buying. Run it through a blacklist check — previously-abused domains come pre-burned.
• Set the domain to auto-renew and verify with the domain expiry checker. Registrar privacy on.

Phase 2: DNS and authentication (Day 0–1)

Do all of this before creating a single inbox.

Order matters: authentication before inboxes, inboxes before warmup, warmup before campaigns. Every shortcut here is repaid with interest as a deliverability problem in weeks 3–6.

Phase 3: Inbox creation (Day 1–2)

• 2–3 inboxes per domain, maximum. More inboxes per domain concentrates risk and looks unnatural.
• Use real human names (sarah@, james.t@) — not sales@, info@, or outreach@.
• Complete every profile: photo, signature, timezone. Send a few manual emails to colleagues and reply to them.
• Use the inbox count calculator to size total infrastructure against your monthly lead targets.

Phase 4: Warmup (Weeks 1–4)

New inboxes need 3–4 weeks of gradually increasing, engagement-positive activity before they can carry campaign volume. Enable warmup in your sending platform and follow a ramp like:

• Week 1: 5–10 warmup emails/day per inbox
• Week 2: 15–20/day, replies enabled
• Week 3: 25–35/day, begin mixing 5–10 real sends/day
• Week 4: 40/day warmup, ramp real sends toward 20–30/day

Full detail in the warmup guide, and the warmup readiness checker tells you if you're actually ready to send.

The 3–4 week problem — and the shortcut that actually works

The warmup period is the single biggest bottleneck in cold email operations. If you're replacing burned infrastructure or onboarding a client who needs to launch now, a month of dead time is often commercially unacceptable. This is the legitimate use case for buying pre-warmed infrastructure: providers like WarmInboxes sell inboxes on domains that have already been through a proper warmup cycle, so you can be sending real campaigns within days instead of weeks. Run the warmup time-saved calculator to compare the economics for your volume.

Phase 5: Go/no-go verification (before first campaign send)

If any item fails, fix it before sending. A campaign launched through a failed gate doesn't just underperform — it damages the asset you spent four weeks building. And keep one rule permanent: your main company domain never sends cold email. Ever.
