The Challenge: Losing 80% of Leads Due to Slow Manual Follow-Up
A fast-growing marketing agency was struggling to convert inbound leads. Their sales team relied on manual SMS outreach and manual follow-up logs, resulting in slow response times and an estimated 80% lead drop-off rate. As email open rates declined across their industry, they needed an automated, high-touch communication channel that didn't consume hours of manual staff time each day.
The Solution: An Automated Twilio & Google Apps Script SMS Workflow
We engineered an automated SMS nurturing workflow that intercepts incoming leads instantly. Built using the Twilio API and customized Google Apps Scripting, the system triggers tailored SMS sequences without human intervention:
- Instant Lead Response: Triggers a personalized welcome SMS within 30 seconds of form submission.
- Multi-Sequence Nurturing: Deploys a 10-template automated campaign conditioned on user interactions.
- Real-Time Tracking & Logs: Syncs reply rates and status updates directly back to their central agency dashboard.
The Results
- 75% Reduction in Lead Leakage: Automated timing ensured zero leads slipped through the cracks.
- 400% Higher Engagement: SMS response rates outperformed traditional email campaigns significantly.
- 250% Conversion Boost: Converted significantly more cold enquiries into booked discovery calls.
