Tonic SMS Automation System
A campaign automation system that connects Kit.com and Twilio to send targeted SMS at scale. It gives marketing teams a repeatable way to reach subscribers, track delivery, and run campaigns without manual sending.
The challenge
Client challenge
Tonic needed to reach 10,000+ subscribers with targeted SMS campaigns but had no system for automating delivery at scale, managing campaign sequences, or tracking response behaviour without manual effort.
The build
What I built
I integrated Kit.com subscriber management with Twilio's SMS API through n8n — enabling automated campaign scheduling, subscriber segmentation, and delivery tracking across the full subscriber base.
- Kit.com subscriber sync and segmentation
- Twilio SMS delivery engine at 10K+ subscriber scale
- n8n workflow orchestration for campaign sequencing
- Campaign scheduling with time-zone awareness
- Delivery and response tracking per campaign
The outcome
Measured outcomes
98% deliverability across 10,000+ subscribers. Campaigns launch and execute entirely on autopilot from a single trigger — Tonic's team went from manual sending to a fully managed, measurable SMS operation.
