Up to 65% Reduction in Spam/Fake Lead Submissions. Anti-Spam System Implemented for a Home Improvement Company.

Industry: Home Improvement (Windows & Doors) Tech: MODX, PHP, Firebase, Twilio API, Google APIs

Overview

The sales team of a home improvement company was spending too much time dealing with low-quality, fake, and duplicate leads. TSYFRA built a custom lead validation layer tightly integrated with the existing MODX website to ensure only clean, high-quality leads reached the CRM and sales team.

Problem

The company’s digital marketing campaigns were driving traffic, but:

  • A significant portion of form submissions were spam or test entries.
  • Incorrect or incomplete phone numbers and addresses reduced contact rates.
  • Fake leads created confusion and wasted sales team capacity.

Solution

Tsyfra implemented a server-side lead validation system that runs between the website forms and the internal lead processing flow:

  • Developed a validation layer in PHP, integrated directly with MODX forms.
  • Added rules to detect spam patterns, bots, and suspicious submissions.
  • Implemented address and ZIP code validation against trusted data sources.
  • Implemented phone validation logic to catch fake numbers, wrong formats, and obviously invalid numbers.
  • Provided submission logs, structured error messages, and alternative actions when data fails validation.

Outcomes

The new system transformed how the sales team interacts with inbound leads:

  • Up to 65% reduction in spam and fake lead submissions entering the pipeline.
  • 30-45 minutes saved daily for the sales team. Less time spent on manual lead cleaning and more time on real prospects.
  • +25% improved lead quality score. More reliable and complete contact data, improving follow-up quality and increasing close-rate potential.
  • Near 100% accuracy for phone & ZIP format validation.
  • A clearer picture of campaign performance based on clean data.
