About SpeedSize
SpeedSize holds the only patent on an AI media CDN driven by neuroscience. It rebuilds a store's images and videos to load five to ten times faster while preserving one hundred percent of the original quality.
The mechanism auto-fixes Core Web Vitals warnings, cuts file sizes by up to ninety percent, and integrates as a plug-and-play layer on Shopify, Magento, and WooCommerce with no code. The category is enterprise-grade media CDN, head-to-head against Akamai, Cloudflare, and CloudFront. GAP's public POC against Akamai on 200M live requests is the flagship credibility anchor. Allbirds, MÁDARA Cosmetics, Leibish Jewelry, Cozey, Nkuku, and 35+ other premium brands run in the reference library.
What we did
01
LCP-specific personalization at scale.
- Scraped each prospect's actual Largest Contentful Paint score before every send. Openers went out with the measurable number in the first line: "your 4.2s LCP exceeds Google's 2.5s threshold."
- Personalization stopped at what could be measured. No fabricated urgency. A prospect with a healthy LCP got a different track.
- Core Web Vitals status drove the opener across the whole book, measurable and defensible per store.

[First name], your website's 4.2s LCP exceeds Google's 2.5s threshold, likely impacting conversion rates. [Category] brands typically lose 6 percent in sales due to slow-loading product media.
SpeedSize's AI-neuro Shopify integration guarantees 5x faster loading of your images and videos while reducing file sizes by 90 percent, and auto-fixes Core Web Vitals red warnings. Our [category] clients have seen 6 to 34 percent higher conversions.
P.S. We can set up a risk-free AI-CDN on your staging environment to prove results before commitment.
Opener built from the prospect's actual measured LCP score and their category-specific proof (Leibish for jewelry, MÁDARA for skincare, Allbirds for apparel). Same template, different measured score per prospect.
02
Category-calibrated social proof.
- Jewelry prospects heard about Leibish (38% Core Web Vitals improvement while keeping premium diamond imagery).
- Skincare prospects heard about MÁDARA (LCP 4.6s to 2.3s, 17% add-to-cart lift in 4 weeks). Apparel heard about Allbirds (32% higher mobile conversions, 85% less media storage).
- Enterprise prospects heard about GAP (200M live requests validated head-to-head against Akamai). Every proof point matched the prospect's category. No generic "trusted by hundreds."
03
Multi-variant testing at unusual depth.
- Every campaign ran three to four Email 1 variants concurrently: a named-executive observable, a role-specific pain frame, an industry-stat opener, and a video-forward hook led by the CTO's compression breakdown.
- Reply-rate attribution split by variant, so we could tell which opener style did the work per tier, not per campaign.
- Subject lines A/B/C tested in parallel: "your collection grid speed" against "your homepage editorial image" against "mobile / peak season."
04
Sponsored test as the trust anchor across every campaign.
- Every campaign closed on a version of "a fully sponsored media speed test for you, no commitment."
- Free staging AI-CDN, free integration, free PageSpeed audit, and a 14-day money-back test were named as the actual offer, not softeners.
- The whole evaluation was positioned as risk-free without ever using the word "trial." The buyer walks in knowing they walk out with data either way.
05
Peak-season reactivation as a dedicated track.
- A separate track built around peak-season timing, launched to warm leads and past conversations gone quiet, acknowledging the earlier thread directly.
- Peak-season pain data anchored the urgency: 53% bounce after one slow page, mobile driving over half of peak traffic.
- Three sub-variants: peak-season prep, paid-media-spend efficiency, and mobile-load-time framing.
06
Shopify app retargeting for installed-but-lapsed prospects.
- Dedicated track for prospects who installed SpeedSize's Shopify app but never activated a client ID, a real intent signal cold outbound would treat as cold.
- Direct opener: "saw someone from your team installed our app but didn't grab the client ID, are you exploring ways to improve site speed?"
- The sequence closed with an actual free AI-optimization offer, since the technical setup was already halfway done.
