Mode 2: Generation (AI drafts, reps send). Regie.ai generates personalized sequences; reps review and send.
Mode 3: Autonomous (AI does everything). 11x, Artisan Ava send autonomously with no human in loop.
Infrastructure layer (deliverability)
Even the best AI content fails without warmed-up domains and proper inbox rotation. The infrastructure layer:
