EZ Bombs went viral on TikTok Shop, but their email ecosystem wasn’t built to convert or retain customers. We transformed email into a revenue-driving engine, turning first-time buyers into repeat customers through structured testing and a performance-driven strategy.
The Challenge
EZ Bombs had strong top-of-funnel momentum from TikTok — but no system to capture and maximize that demand. Their email lacked structure: no clear testing framework, weak segmentation, and campaigns without direction. Engagement was low, click-through rates were underperforming, and revenue from email was far below its potential. They needed more than good-looking emails — they needed a system that converts.

THE PROCESS
We rebuilt their email ecosystem from the ground up — focusing on performance, not just design. First, we fixed the foundation. Every core flow was optimized, restructured, and segmented properly to ensure the right message reached the right customer at the right time. Then, we implemented a structured testing engine — continuously iterating on subject lines, offers, angles, and creative to identify what truly drives engagement and conversions. On the campaign side, we introduced a strategic calendar aligned with product demand and buying behavior — ensuring every send had a clear purpose, angle, and revenue goal. Finally, we redesigned their emails to match the high-energy, scroll-stopping feel of TikTok — but built for conversion, not just aesthetics.

RESULTS
By transforming email into a structured, performance-driven channel, we turned Klaviyo into one of EZ Bombs’ primary revenue drivers. Beyond the metrics, the biggest shift was in consistency and predictability. Campaigns now generate reliable revenue on a weekly basis, flows convert traffic automatically in the background, and every send is backed by data, not guesswork.
Impact
From underperforming emails to a core revenue channel.
EZ Bombs proves that going viral is just the start — real growth comes from building systems that capture, convert, and retain that demand.

“Before working with 551, we were riding the TikTok Shop wave but leaving money on the table, we weren’t really tapping into email. There was no real system: inconsistent campaigns, no testing, and weak results. 551 brought structure, rebuilt our flows, and introduced proper testing. We quickly started seeing what worked. They focus on performance, not just design and it shows. Now email is a reliable revenue channel for us instead of a guessing game.”
