How We Cleaned 25,000 HubSpot Records and Tripled a SaaS Company's Email Open Rates

A fast-growing US SaaS company came to us with a CRM in complete chaos — 40% duplicate records, 12 inconsistently formatted fields, and thousands of emails that had bounced in recent campaigns. Their marketing team had stopped trusting the data entirely. Here's exactly how we fixed it.

B2B Lead Generation · UK Agency

1,200 Verified Decision-Makers Delivered in 4 Days — 3 Deals Closed from First Send

The Challenge

A digital marketing agency needed 1,200 verified contacts — specifically marketing directors and CMOs at US companies (50–500 employees) — for a cold email campaign launching in just 5 days. Their previous lists had 30%+ bounce rates.

Our Solution

Used LinkedIn Sales Navigator with precision filters (title, company size, industry). Enriched each contact via Hunter.io and Apollo, then verified the full list through ZeroBounce with confidence scores and a detailed bounce report delivered alongside the CSV.

2,000 WooCommerce Products Uploaded On-Time for UK Fashion Brand Launch

The Challenge

A UK fashion retailer launching their new WooCommerce store needed 2,000 product listings — each with 6 images, SEO-optimized descriptions, category assignments, size variants, pricing, and stock levels — all ready 1 week before their launch date.

Our Solution

Built a custom CSV import template matching the WooCommerce structure, processed all 2,000 products with correct image URLs, formatted SEO descriptions, assigned categories, and configured product variations. A test batch of 50 was approved before the full upload began.

Our Approach

How Every Case Study Begins

Every successful project follows the same reliable process — no shortcuts, no guesswork.

Understand the Brief

We ask the right questions to fully understand your data, goals, format, and deadline before starting any work.

Plan the Workflow

We select the right tools and build a QC checklist specific to your project before a single record is touched.

Execute with QC

Data is processed in batches with multiple accuracy checks at each stage — nothing moves forward until it passes review.

Deliver & Support

Delivered in your format with a summary report. Free revisions until you are 100% satisfied.
