SendLens
Klaviyo tracks sends. Not performance.
SendLens pulls campaigns, flows, revenue, cohorts, and churn risk into one dashboard. Updated weekly. No spreadsheets.
Used by agencies managing 50+ Klaviyo accounts.
“I used to build a spreadsheet every Monday to see how the previous week went. Now I open SendLens and it's already there.”— CRM Lead, DTC health brand
The problem
Klaviyo tells you what happened. Not what it means.
Revenue lives in one tab. Flows in another. Campaigns somewhere else. You want to know if last week was better or worse than the week before — and Klaviyo won't just tell you. You piece it together manually, or you skip it entirely.
Most performance dips compound quietly for weeks before anyone notices. By the time you see it in a monthly report, you've already lost the revenue.
There's no cohort analysis. No churn prediction. No way to know which customers are about to stop buying. You're guessing who to target — and so is everyone else.

Predictive analytics
Most brands react to churn. You can get ahead of it.
SendLens scores every customer by recency, frequency, and spend. You see who's drifting before they stop buying. Churn risk scores, predicted reorder windows, and second-purchase probability — so your win-back campaigns reach people while they're still reachable.
