How Defrost approaches the work
Defrost starts with your website and the audience you want to reach. It finds people, researches their companies, writes personal emails, sends and follows up. Reply outcomes help shape future emails as evidence builds. When someone replies, you pick up the conversation in one inbox.
The intended experience is one ongoing system. You can adjust the business information, audience and sending settings, pause outreach, or choose whether first emails need approval. Public access is currently through the waitlist.

A useful way to evaluate it
Create two test clients with different permissions. Give each a few sample contacts and have a teammate work the inbox. Confirm that the right people can see, edit and report on only the work they own.
Judge the ongoing work as well as the setup: who maintains the audience, checks the research, changes messages and responds to people? The right choice is the one that matches the responsibilities your team wants to keep.
