Frequently Asked Questions

Everything you need to know about ordering cold-email-ready Microsoft 365 mailboxes.

Is this an official Microsoft 365 license?

Yes. Every mailbox is a genuine Microsoft 365 account created directly through Microsoft—never a grey-market or resold substitute.

Do I own the accounts?

Yes. Accounts are created under your ownership and control. You receive full login credentials.

Why is it cheaper than buying from Microsoft directly?

You're not paying us for the license—you pay Microsoft for that either way. You're paying us to handle the mailbox creation, domain connection, and DNS authentication that would otherwise cost you hours or a hired freelancer.

Can I upgrade later?

Yes. You can add more mailboxes, connect more domains, or upgrade your setup at any time as your outreach scales.

Can I order hundreds of mailboxes?

Yes. Whether it's 10 or 1,000+, our provisioning process scales the same way—just tell us your target volume.

Can you connect my outreach software?

Yes. On request, every mailbox is connected directly inside your Instantly workspace ready to add to a campaign—along with Smartlead, ReachInbox, ManyReach, Lemlist, and most other major outreach platforms.

Do you configure DNS?

Yes. MX, SPF, DKIM, and DMARC are all configured correctly on every domain as part of every order.

Can you help me buy domains?

Yes. If you don't already own domains, we help you purchase affordable outreach-specific domains as part of the process.

Do I need technical knowledge?

No. You don't need to understand DNS, authentication, or mailbox configuration—we handle all of it.

How fast is delivery?

Most orders are delivered within 24 hours of receiving your domain and mailbox count details.

Can I cancel anytime?

Yes. There are no long-term contracts—you're free to stop or scale down whenever you need to.

Do you provide Google Workspace as well?

Yes, Google Workspace inboxes are available as a separate option if you prefer that platform instead of, or alongside, Microsoft 365.

What happens if something breaks?

If a configuration issue traces back to our setup, we fix it at no additional cost.

Is this the same as a generic Microsoft 365 reseller?

No. Resellers typically stop at selling you the license. We provision the mailboxes, configure every DNS record, and optionally connect your outreach software—a complete cold-email-ready setup, not just an account.

Will these mailboxes already be warmed up?

Mailboxes are delivered fully configured and ready for warmup to begin—warmup itself is a separate service if you'd like us to handle that too.

Can I mix Microsoft 365 and Google Workspace mailboxes?

Yes. Many clients run a blend of both across their domains for added sending diversity.

Do you support agencies managing multiple clients?

Yes. Agencies regularly order mailboxes in bulk across many client domains through us.

What information do you need from me to get started?

Just your target mailbox count and your domains (or confirmation that you'd like help purchasing some).

How do I get exact pricing for my order?

Choose a plan above, or tell us your mailbox and domain count on a quick call and we'll send back straightforward pricing—no hidden fees.
