E-Commerce IT Audit & Speed Fix

The Challenge

Artisan Goods Co. was spending heavily on ads but seeing a high drop-off at checkout. Additionally, customers were complaining about not receiving order confirmations.

The Solution

We identified two critical bottlenecks:

  1. Script Bloat: 45+ unmanaged tracking scripts were stalling the checkout thread.
  2. Email Authentication: Their domain had no DMARC policy, causing Gmail to flag receipt emails.

The Result

We implemented aggressive script loading strategies and locked down their email sending domain. Checkout speed improved by 2.5x, and open rates for transactional emails tripled overnight.

"We didn't realize how much the technical debt was costing us until Interprogram fixed it in a weekend."
