For teams sending 10k-1M+ emails/month, infrastructure isn't just your sending tool—it's the entire system of domains, inboxes, and DNS records.
Your cold email infrastructure is the entire system of domains, inboxes, and DNS records—not just the sending software you use.
At scale, infrastructure failure is deliverability failure. A single misconfigured DMARC record can tank an entire domain portfolio.
Scaling from 10k to 100k emails/mo requires a shift from managing campaigns to managing infrastructure and automated domain rotation.
In the context of cold outbound, infrastructure refers to the complete technical stack required to send email at scale while protecting deliverability. This goes beyond a single sending tool; it encompasses the portfolio of sending domains, the pool of inboxes, DNS configurations (SPF, DKIM, DMARC), IP addresses, and the automation logic that manages warmup, rotation, and health monitoring. For operations sending over 100,00 a month, infrastructure is the primary driver of campaign success or failure.
When you move from sending hundreds of emails to hundreds of thousands, the conversation shifts from copy to technical architecture. Infrastructure becomes the bottleneck or the enabler.
Building resilient infrastructure requires a systematic approach that assumes failure and automates recovery. It's not about finding the one perfect setup, but building a system that can withstand stress.
DMARC records every day.Many teams fail to scale outbound because their infrastructure breaks before their strategy does. These are the most common failure points:
Teams sending 10k-1M+ emails/month need to understand that infrastructure is the foundation of sustainable outbound. To maintain domain reputation, ensure deliverability, and scale safely, your focus must shift from campaign tactics to building a resilient sending apparatus.
