Shopify stores have no idea how effective Retention.com is for growing email lists.
Retention.com works 10 to 15 times better than the next best option out there.
What we achieved with this customer’s implementation showcases exactly why our solution is transforming email marketing.
We doubled their list size in just 40 days while improving deliverability and growing product views by 25%.
Here’s how this implementation transformed Bruce Bolt’s email marketing strategy.

Initial Challenge
The original welcome series had very high positive engagement, but also had high negative engagement.
This typically isn’t a problem because it’s such a small percentage of the overall email flow going out.
But if you’re sending a welcome series, it just hurts to see those numbers.
The Solution
When new contacts come through your website, instead of placing them in a standalone welcome series, we held them in a segment and included them in a larger newsletter.
This approach minimizes the impact of any negative engagement, as they make up just 1% of the total recipients, diluting their effect within the broader send.
The Numbers
Here are some numbers before and after showing you the difference.
Before Implementation
We were putting 500 to 1000 contacts per day into Klaviyo’s welcome series.
The complaint rate was 0.48 (it needs to be below 0.1, ideally 0.05), and the unsub rate was 3.56%—which in a flow looks like garbage.
Previous Newsletter Performance
Their old newsletter showed incredibly low spam rates with a size of 136K and unsubs at 0.2%. These metrics set our baseline for active on-site engagement and page views.
After Implementation
With the Bruce Bolt implementation, email list growth was tremendous in just the first 40 days.
The spam rate and unsubscribe rate didn’t increase in any meaningful way that caused concern.
Most importantly, product views grew from 2.3k to 4k — that’s almost 100% growth with not as much list size growth.
Conclusion
The Bruce Bolt implementation highlights how Retention.com can revolutionize email marketing strategies.
By doubling their email list in just 40 days, we not only improved deliverability but also boosted product views by nearly 100%—all while maintaining strong engagement metrics and minimizing the impact of negative interactions.
This approach proves that growing your list doesn’t have to come at the cost of performance.
