Warming a new domain by hand means sending a trickle of real, replied-to emails for weeks, and this automates that slow ramp with a large network of real accounts. It starts small, grows volume gradually, and simulates opens and replies so providers learn to trust you before you send cold. Useful when you are standing up a fresh sending domain and cannot babysit the warmup yourself.
Written specifically to answer this question, pulling together response-rate curves across follow-up counts so you can see exactly where the returns flatten out. Useful as a sanity check against the 4 to 6 touch range in our short answer.
Instantly is built specifically for cold outreach, so this guide is framed around your exact problem rather than transactional email in general. It explains Gmail and Outlook's current bulk sender rules and gives specific record examples, which is useful once you already understand the basics and want the cold-email-specific version.
