What makes Infrarr different from other providers?

Infrarr runs on Tier 1 Microsoft Azure infrastructure, not resold inboxes. You get enterprise grade deliverability, fully isolated tenants, and cost economics that are impossible on Gmail based stacks.

How fast can I start sending?

You can start low volume sending in just 3 days with meaningful results. We still recommend the full 2 week warm up for long term mailbox health, but you don't have to wait to see ROI.

Can I bring my own domains?

Absolutely. Plug in domains you already own and we'll configure them on our Azure infrastructure. SPF, DKIM, DMARC, and tenant provisioning included.

Is 1 million emails per month really the ceiling?

That's the baseline. Infrarr scales linearly. 1M, 10M, or more. Enterprise contracts available for higher volumes or custom infrastructure needs.

Who is Infrarr built for?

Agencies, lead gen companies, enterprise sales teams, and anyone doing serious cold outreach at scale. If you're sending more than 100k emails per month, the math works overwhelmingly in your favor.

How does deliverability compare to Gmail?

Higher. Azure Tier 1 IPs have better reputation, tenant isolation prevents cross contamination, and pre configured authentication means your domains are ready to land from day one.
