In-Depth

Case Studies

The full story behind 3 of our most impactful projects β€” challenge, solution, and results.

01
🏒
SaaS / CRM
CRM Data Cleanup & HubSpot Migration

The Challenge
A US-based SaaS company came to us with 25,000+ HubSpot records β€” 40% were duplicates, field formats were inconsistent across 12 custom fields, and thousands of emails had bounced in recent campaigns. Their marketing team was blind because the data was too dirty to trust.
Our Solution
We ran a full data audit, removed all duplicates, standardized every field to a consistent format, enriched 3,200 missing company names via LinkedIn research, and ran the complete list through ZeroBounce. Final data was re-imported directly into HubSpot with a field mapping guide.

“Our campaign open rates went from 12% to 34% after the cleanup. The ROI was immediate and undeniable.” β€” Head of Marketing, USA SaaS Company

02
🎯
B2B Lead Generation
LinkedIn Prospecting for Sales Agency

The Challenge
A digital marketing agency needed 1,200 verified contacts β€” specifically marketing directors and CMOs at US companies with 50–500 employees β€” for a cold email campaign launching in just 5 days. Previous lists they purchased had 30%+ bounce rates.
Our Solution
We used LinkedIn Sales Navigator with precision filters (title, company size, industry, geography). Each contact was enriched with work email via Hunter.io and Apollo, then the full list was verified through ZeroBounce with a detailed bounce report and confidence scores provided.

WooCommerce Mass Product Upload

The Challenge
A UK fashion retailer was launching a new WooCommerce store and needed 2,000 product listings uploaded β€” each with 6 images, SEO-optimized descriptions, category assignments, size variants, pricing, and stock levels β€” all within one week before their launch date.
Our Solution
We built a custom CSV import template matching their WooCommerce structure, processed all 2,000 products with correct image URLs, formatted descriptions, assigned categories, and configured product variations. A test batch of 50 was approved first before the full upload.
