Case Study: DirectMail.io achieves a 47% boost in sales leads with Twilio Autopilot and IVR

How Directmail.io Boosts Sales Leads by 47 Percent Using Twilio Autopilot and Ivr

DirectMail.io is an omnichannel direct-marketing platform that combines direct mail, messaging, telephony, landing pages and analytics to drive personalized campaigns at scale. Facing a limitation of static, linear lead surveys and a long-standing Twilio IVR setup, the company wanted to add AI-driven, customizable conversational experiences to move more prospects down the funnel and improve conversion intelligence for clients.

In one month DirectMail.io built "Salli" using Twilio Autopilot—an NLU-powered virtual assistant that routes calls, captures speech-to-text transcripts, sets appointments, and runs natural-language surveys across voice, SMS and web. The automation delivered measurable gains: a 47% increase in sales leads overall and a pilot that produced a 67% appointment-setting rate—more than double the live call center—while providing richer data and 24/7 coverage.
