Email and SMS remain two of the highest-ROI marketing channels available. Guy Levin has built systems that send millions of messages, and more importantly, he has built the AI that ensures each one lands with the right person at the right time.

Multi-Channel Outreach Done Right

Most businesses treat email, SMS, and push notifications as separate channels with separate strategies. That is a mistake. These channels work best as a coordinated system where each message reinforces the others and timing is orchestrated across all touchpoints.

Levin has designed and executed campaigns across all three channels for businesses ranging from e-commerce to B2B services. The key is understanding which channel fits which message type: email for depth, SMS for urgency, push for re-engagement.

SortExpress was built in part to solve this exact problem. It does not just optimize landing pages — it handles email, SMS, and push notification campaigns, automatically testing variants and routing traffic to the highest-performing combinations.

The SortExpress Advantage

Traditional A/B testing in email marketing is slow and limited. A typical test compares two subject lines, picks a winner, and moves on. SortExpress runs continuous multivariate testing across channels simultaneously. It rotates creative, adjusts send times, and optimizes conversion paths in real time.

This is the system behind the +35% conversion rate improvements and -50% lead cost reductions Levin has delivered. It is not guesswork or "best practices" — it is live data driving every decision, every send, every notification.

The PCT patent behind SortExpress protects this methodology because it genuinely changes how businesses approach multi-channel optimization. It is not an incremental improvement. It is a fundamentally different approach.
