Inboxes · Azure, at cost
Stop paying for cold-email inboxes. The exact same Azure inboxes resellers sell you for $1 - without the markup. Get 100 inboxes for as low as $5 at scale.
Two plans
Sending up to ~5,000/day? Stick with Simple. We handle everything - one bundled price, no setup. Pushing 25,000+/day? Power is the flagship - per-unit cost to the floor, every active customer runs on it.
Simple plan
Start hereEach inbox sends 5 cold emails a day - that's 500/day per domain. Tenants, license, credits - we handle the complexity for you (or you can, if you want). Buy 10 orders for $300, send 5,000/day. Don't worry about anything else.
Power plan
25k+/day · flagshipA lot more complex. You pay a license, bring your own Microsoft tenants, manage credit allocation. Every active customer is on this - per-unit cost to the floor at scale. Covered down the page →
Tenant source (Power plan)
Simple plan
10 domains$300/mo
Power plan
10 orders · Growth$222/mo
At 5,000/day, Simple is the move. 10 orders × $30 = $300/mo. No tenants, no licenses, no credits to manage.
The markup
We give you direct access to the same tech resellers and agencies use. You bring the tenant, we run the automation. Same inbox. Same deliverability. 95% less cost.
Reseller cost
$1.00 /inbox
What you pay Smartlead, Maildoso, or any other reseller for an inbox.
Underlying cost
$0.05 /inbox
What it actually costs to provision an Azure mailbox once you have the tenant.
With OutEngine
$0.05 /inbox
Direct access to the deployment tech. Same primitive. No markup.
What you get
Direct access to the deployment automation. The DNS configuration. The authentication setup. Everything they wrap in a $1/inbox markup - available to you for the underlying cost.
100 per domain
Azure allows 100 inboxes per domain - not 3, like most people think. One domain, massive sending capacity.
One-click export
Your inboxes work with the tools you already have. Export directly without manual CSV uploads.
Auth automated
The technical layer that takes hours to configure manually - done in seconds, every time.
6 - Sign up to sending
Designed to be as simple as possible. The hard part is the automation underneath - you never see it.
Sign up
Email and password. 60 seconds. No card required to explore.
Pick a plan
A flat monthly fee unlocks the deployment platform. Then create as many inboxes as you want for the underlying cost.
Add a tenant
A Microsoft 365 tenant is the admin account that hosts your inboxes. Bring your own (~$5/mo direct from Microsoft) or buy from us ($15/mo, fully managed).
Upload domains
Each domain spawns 100 inboxes. Upload 20 domains, get 2,000 inboxes. The math scales linearly - no surprise overage fees.
Deploy
Watch your inboxes provision in real time. The platform runs thousands of lines of automation in the background - SPF, DKIM, DMARC, the lot.
Start sending
One-click export to SmartLead, Instantly, or whatever you use. Or use the built-in sequencer.
The tech underneath
Built on Microsoft 365. The same infrastructure Smartlead, Maildoso, and every other reseller in this space uses. Same inboxes, same deliverability, same daily limits. No magic. Just no markup.
The math
The difference
We're not selling you a different inbox. We're selling you the automation that resellers built and gatekept - so you can do it yourself.
Same Azure infra. Same Microsoft tenant. Same deliverability. The difference is whether the markup ends up in someone else's pocket or yours.
Power plan · our flagship
What we're known for. Every active customer runs on Power. Three things you assemble: an OutEngine license, credits for each order you provision, and a Microsoft 365 tenant sourced wherever you want. We do the deployment automation. You own everything.
01 - License
Flat monthly fee. Pick a tier that matches your volume - from $97 to $697. The tier is the cap on orders you can run.
02 - Credits
Per-order, per-tenant deployment fee. Pay-as-you-go on top of the license. Only billed on what you actually run.
03 - Tenant
A Microsoft 365 tenant per order. $1.50 from Indian resellers (most common). $5 from US/EU sources (premium).

All tiers add $1 per order in credits + your tenant cost.
Tenant sourcing
Most resellers in this industry sell Indian tenants - that's the cheapest. US and European tenants run higher but carry more sender weight. You choose, we deploy.
Indian source
~$1.50 /tenant
Most-common reseller source. Cheapest. Same Microsoft 365 license under the hood - just different signup geography.
US / European source
~$5 /tenant
Premium source. Higher cost, more trusted sender geography. Worth it for higher-stakes campaigns.
Sending 25,000+/day?
Tenant sourcing, license tier picking, credit pre-provisioning, deliverability strategy. We do live setup walkthroughs for senders pushing serious volume. 25k/day is the cutoff.
Simple plan
If you're not pushing 100,000/day and don't want to think about tenants, licenses, or credits, the Simple plan collapses it all to one number: $30 per domain per month. 500 sends/day per domain. No assembly required.
