Cold Email Infrastructure at Scale: Deliverability, Setup & What Drives Demos
Sending thousands of cold emails is technically easy. Getting those emails consistently delivered — and getting the right prospects to actually respond — is much harder.
In this practical session, we’ll break down how to build cold email infrastructure for higher-volume B2B outbound, with a strong focus on deliverability and setup.
We’ll cover how domains, mailboxes, authentication, sending patterns, volume, reputation and monitoring affect whether emails reach the inbox — and the common mistakes that cause outbound infrastructure to break down as volume increases.
But deliverability is only one part of the equation. An email reaching the inbox does not automatically turn into a reply or demo.
We’ll also look at the other factors that determine outbound performance, including ICP and lead-list selection, data quality, offer, messaging and personalization — and how these pieces work together as one outbound system.
The goal of the session is to help founders and GTM teams understand where cold outbound usually breaks, what to monitor, and how to build the infrastructure properly before simply increasing sending volume.
