We engage with your emails to teach inbox providers not to send your emails to spam. Our clients have seen their open rates more than DOUBLE within 1-2 weeks! Highly engaged recipients not only open emails, but scroll down as they read. So long as the content is longer than the page, this should be done for nearly all opened emails. When a recipient goes out of their way to take an email out of spam, they are telling the inbox provider, hey, you made a mistake. Moving an email from the promotions folder to the primary inbox tells inbox providers that you disagree with their sorting criteria and it and similar emails should go to the primary inbox. Demonstrates that recipient is interested in the content of your email. We have a set of random generic replies we use for this. Marking an email as important can essentially be interpreted by the inbox provider as "This email is extremely valuable, never send it to spam."

Adaptive Security is the security layer for the AI era, protecting organizations and their employees from modern cyberattacks. AI has changed how every company works, and how every company gets attacked. Employees use AI tools IT doesn't know about. Attackers craft deepfakes, vishing calls, and spear phishing emails that get past filters. Adaptive addresses all of it in one unified platform: managing AI tool usage before it becomes a liability, training employees on the threats they'll actually face, simulating AI-powered attacks, and protecting the inbox and browser so threats never reach their intended targets. Because it's one platform, Adaptive develops a complete risk picture and uses it automatically, applying targeted training, attack simulations, and policy controls to lower risk over time. More than 1,000 organizations run Adaptive to manage their human security program, having raised $150M+ from NVIDIA, Andreessen Horowitz, Bain Capital Ventures, and Citi Ventures.
