Not Sure Which to Pick?

Google, Microsoft, or Azure?

Each platform has a different sweet spot. Here's how to choose based on your volume and targets.

Google Workspace

The default choice
Gmail infrastructure is the most widely trusted sending environment. Easiest to warm up, strongest baseline reputation, works with every sending tool.
Fastest warmup curve
Best deliverability to Gmail inboxes
Simplest DNS setup
Pick this if: You're starting out, targeting mixed audiences, or want the least friction.

Microsoft 365

For B2B enterprise
Most enterprise companies run Outlook. Sending from Microsoft infrastructure to Microsoft recipients improves placement in corporate inboxes.
Better placement in Outlook/Exchange
Tenant-level security controls
Anti-spam policy configuration
Pick this if: Your prospects are enterprise B2B running Outlook or Exchange.

Microsoft Azure

For serious volume
Enterprise bulk infrastructure. Where standard plans cap out at 50–100 users, Azure scales to 300–1000+ with full tenant control.
300–1000+ user capacity
IP planning & reputation isolation
Agency-grade multi-tenant setup
Pick this if: You're an agency or running high-volume outbound at scale.

Every Plan Includes

What We Build For You

Regardless of platform, every infrastructure build covers these fundamentals.

Domain Architecture

Dedicated sending domains structured for reputation isolation, so one burned domain never takes down your whole operation.

Authentication Stack

SPF, DKIM, and DMARC configured and aligned correctly — the technical foundation inbox providers check first.

Inbox Provisioning

Business inboxes created at reseller pricing and distributed across domains for safe sending volume.

Warmup & Limits

Gradual warmup schedules and sending limits calibrated to build reputation without triggering spam filters.

Tool Integration

Connected and tested with Instantly, Smartlead, ReachInbox, or whatever platform you're running campaigns from.

Ongoing Support

Direct WhatsApp access for DNS questions, configuration changes, and scaling guidance as you grow.

Common Questions

Cold Email Infrastructure FAQs

Do prices include the Google or Microsoft accounts?
Yes. Every plan price includes the reseller accounts, domain configuration, authentication setup, and warmup — there are no separate setup fees or hidden licensing charges.
How many domains and inboxes do I actually need?
It depends on your daily sending volume. A safe rule is roughly 30 emails per inbox per day, with 3 inboxes per domain. So 1,000 emails/day needs around 33 inboxes across 11 domains. Tell us your target and we'll size it exactly.
Why not just send from my main business domain?
Cold outreach carries spam-complaint risk. If your primary domain gets flagged, your entire company's email — sales, support, invoices — starts landing in spam. Dedicated sending domains isolate that risk completely.
What's the difference between Google, Microsoft, and Azure?
Google Workspace is the easiest to warm up and works well for most audiences. Microsoft 365 places better when your prospects are enterprise B2B on Outlook. Azure is bulk infrastructure for agencies needing 300–1000+ users with full tenant control.
How long does setup take?
Most setups are delivered within 24–48 hours. Larger Azure builds and multi-tenant enterprise configurations can take 48–72 hours depending on DNS propagation and scale.
Can I upgrade later as I scale?
Yes. Most clients start on Starter or Growth and upgrade as volume increases. We handle the migration and add domains and inboxes without disrupting your active campaigns.
Do you offer infrastructure for agencies with client accounts?
Yes. The Enterprise and Azure tiers are built for agency use — multi-tenant structuring, per-client reputation isolation, and scaling blueprints for managing several client environments at once.
