Klaviyo Email, SMS & Customer Data
Klaviyo is one of the most capable email, SMS, and customer data platforms for ecommerce brands, with deep integrations into Shopify, BigCommerce, and other storefronts. System Strats helps brands set up Klaviyo properly, build flows that drive real revenue, segment customers based on actual behavior, and measure results so marketing spend turns into predictable growth.
For ecommerce brands, owned channels (email and SMS) are often the single biggest lever for predictable, profitable growth. Klaviyo is the platform that has won most of that market because it does the job well, but only when it is set up thoughtfully. A sloppy Klaviyo account leaves real money on the table every week.
Deliverability is quietly tanking because of bad authentication, low engagement, or sending practices that inbox providers do not like. You are paying for a list that is mostly not seeing your emails.
Welcome, abandonment, and post-purchase flows were built at launch and never touched again. They are still running, but the content is stale, the logic has holes, and the revenue is nowhere near what it could be.
New customers, loyal repeat buyers, and lapsed shoppers all get the same email. You are missing out on the personalization that actually moves the needle.
Klaviyo is not talking to your ad platforms, your BI tools, or your CRM. You have customer data, but it is not flowing into the decisions you actually make.
We treat Klaviyo as a revenue channel, not a marketing afterthought. That means fixing deliverability first, then building the highest-impact flows, then adding the segmentation and integrations that let the account keep improving over time. Every recommendation ties back to a number we can measure.

Learn More →We review your current Klaviyo setup: deliverability, flows, segments, integrations, and recent performance. We identify the biggest gaps and opportunities.
We fix authentication, clean up suppressions, and rebuild the core setup so the rest of the work is standing on solid ground.
We build or rebuild the flows that drive revenue, set up a campaign calendar, and establish testing patterns that keep improving results.
We stay involved for regular reviews, new flows, seasonal campaigns, and integration work as the business grows.
We work across Shopify, BigCommerce, WooCommerce, and ERPs, so we understand Klaviyo in the context of the broader ecommerce operation. That broader view helps us build Klaviyo setups that actually integrate with inventory, fulfillment, and customer service rather than treating email as a silo.
