Wholesale-Priced Inboxes (Outlook + Google)

Most people pay 10–20× markup for inboxes. We’ll show you how to cut out the middlemen, source inboxes at wholesale, and scale them safely without deliverability issues.

Why This Matters

Resellers often bundle hundreds of cold-emailers on the same infrastructure and sell you inboxes with a 10–20× markup. That’s expensive and risky. When someone else burns their setup, you can get dragged down.

  • Every $1 saved on infra = $3–$10 you can redeploy into growth, more lists, better offers, or building an even bigger infra.

  • Outlook from $0.02–$0.045/inbox/month

  • Google from $1.15/inbox/month

  • Works at small scale and at 10K+ inbox scale

Use this to skip middlemen, cut spend, and keep your sending health in your control.

The Problem With Retail & Trials

  • Microsoft retail (Basic): ~$7.20/mo per inbox. 100 inboxes = $720+/mo.

  • Free trials: Max ~60 days (30 + 30 extension), 25 licenses per plan per tenant and bad IPs for outbound → tenants get flagged fast. Not worth it.

The Usual “Solution” (and why it’s broken)

  • Resellers charge $30–$90 per 100 inboxes… which still hides a 10–20× markup and shared-risk infra. If a reseller gets banned, everyone under them gets cooked.

The Fix: Become a Microsoft CSP (Cloud Solution Provider)

Real costs we see:

  • Standard license: $0.045/inbox/month

  • Per tenant: Up to 100 inboxes on one domain.

Two ways to do it:

A) Get your own CSP relationship

  1. Apply to Microsoft CSP (Cloud Solution Provider partner). Short onboarding + vetting calls, then you’re live. Takes 3–6 weeks before you can provision tenants.

  2. Connect a tenant provider (they mint licenses from the MS backend).

  3. Once live: buy Standard licenses ≈ $0.045/month/inbox.

B) Use our pass-through (fastest start)

  • We maintain multiple CSPs. Inside Citadel, we pass tenants at cost so you can launch now and move to your own CSP later.

  • $10/tenant (all fees included). Delivered within 24h.

  1. Automation for setup (optional but crucial at scale). Manually setting 1K+ inboxes is slow; use a script or a provisioning tool.

  • We partner with a provisioning platform, cheap, fast, and saves days. (Invite is inside Citadel 2.0 / DM me if needed.

Safe sending rules (Outlook)

  • Per inbox: 5 cold + 5 warm/day (start here; increase slowly).

  • Per tenant: keep total sends ≤ 1,000/day (2,000 absolute max, not recommended).

Numbers (example)

Let’s say you want to run 10,000 Outlook inboxes (100 tenants × 100 inboxes)

  • Microsoft direct (full price):
    $7.20/inbox × 10,000 = $72,000/month

  • Reseller (10–20× markup):
    Typical: $3–$5/inbox × 10,000 = $30,000–$50,000/month

  • At cost:
    License cost @ $0.045 = $450/mo
    Tenant provider fee $50/tenant = $5,000/mo
    Total = $5,450/mo to move → 1.25M emails/mo safely.

✅ That’s still a 10× ROI vs resellers and a 100× ROI vs full price, while keeping control of your infra.

Retail Pricing (don’t do it)

  • Google Workspace Business Starter (monthly): = $8.40/inbox/month.
    10.000 inboxes = $84,000/mo for ~150–200k sends/day total. Ouch.

Three Real Paths (what resellers actually sell)

  1. Discounted Legit Workspace (best option)

    • Example: F60Host, etc. (we’ve tested a few)

    • Typical cost: $1.15/inbox/mo depending on region/IP mix.

    • Pro: legit licenses, cleanest long-term.

    • Con: usually the most expensive of the three.

  2. Education / Non-profit panels (gray area)

    • Dirt cheap: $0.22–$0.27/inbox (one-time).

    • Limitations: Low daily send ceiling. Accounts can be easily flagged, not reliable for scaling.

  3. Legacy (pre-2012 panels one-time cost)

    • One-time buys like “300 inboxes for $1,500.”

    • Limitations: Low daily send ceiling. Increasingly targeted/flagged by Google.

Recommendation: If you want durability, use Workspace (legit) at $1.15. If you need ultra-low CAC, use EDU/Legacy/NP with strict low-send rules and planned churn.

Quick-Start Checklists

Outlook (CSP)

  • Grab tenants at cost (members) or start CSP app

  • Choose tenant provider (region matters; EU/UK IPs are usually cleaner than US)

  • Script/provision: domain adds, DNS, user creation, auth, warmers

  • Send caps: 5 cold + 5 warm per inbox/day, ≤1,000 per tenant/day

  • Monitoring: domain health, bounce/complaint alerts, auto-swaps

Google (Legit Workspace route)

  • Purchase discounted Workspace (target $1.15/inbox)

  • Configure DNS/auth, warmers, forwarding rules

  • Send caps: keep daily sends conservative; ramp based on positive replies

  • Test region/IP pools; swap any “spicy” sources

FAQ

Q: What region/IP should I choose?
 A: EU/UK are typically cleaner and less abused than US. If your company is US-registered, you’ll likely receive US IPs, still workable, just be more conservative.

Q: Is EDU/NP/Legacy safe?
 A: It’s a grey area. Keep send volume very low, rotate, and expect churn. Great ROI when used properly.

Q: How many inboxes per tenant?
 A: Outlook: up to 100 per tenant. For Google panels, depends on the panel; build small clusters and rotate.

Q: What should my daily sending look like early on?
 A: Start at 1–2/day/inbox, ramp slowly over 2–3 weeks. Maintain warm volume alongside cold.

When the Infra’s Right, the Results Speak for Themselves.
