E-Commerce IT Audit & Speed Fix
"Bloated 6MB homepage payload, unauthenticated emails going to widespread spam."
"Sub-second page loads, verified domain sender signature, clean checkout flow."
The Challenge
Artisan Goods Co. was experiencing performance issues that were directly impacting their sales. A very large homepage payload and an excessive number of unmanaged tracking scripts were creating friction during the checkout process.
In addition, their transactional emails were often being flagged as spam. Without proper domain authentication, order confirmations and shipping updates were not reaching customers, leading to increased support requests and customer uncertainty.
Technical Intervention
Optimization Audit
We performed a thorough audit of the third-party script stack. By implementing Partytown for off-main-thread script execution and removing redundant trackers, we significantly reduced checkout latency.
Asset Optimization
We implemented a modern image optimization pipeline and Edge-level caching via Cloudflare. This reduced the total page size from 6MB to under 1.2MB while maintaining high visual quality.
Domain Authentication
We secured the email infrastructure by configuring SPF, DKIM, and a strict DMARC policy. We also migrated transactional traffic to a dedicated high-reputation sender to ensure reliable deliverability.
Business Impact
Improved Checkout: Achieved a faster checkout completion rate, which helped increase conversions.
Email Engagement: Open rates for order confirmations improved significantly after implementing authentication.
Technical Debt Resolved: Achieved significantly faster page loads across the entire storefront.
Client Feedback
"We didn't realize how much the technical debt was costing us until Interprogram fixed it in a weekend."
