Built for Klaviyo agencies. Branded as your own. Delivered to Google Slides.

SendLens weekly performance dashboard
The problem

Klaviyo gives you the numbers.
You still have to make sense of them.

Revenue, campaigns, flows, subscriber growth and engagement all sit in different parts of the platform.

To understand what changed, why it matters and what needs attention, you either spend hours pulling it together or work without the full picture.

  • 1

    Problems get spotted too late

    A drop in flow revenue or engagement can continue for weeks before it appears in a monthly report.

  • 2

    Useful customer analysis is often out of reach

    Cohort reporting, churn signals and customer-level analysis can require more expensive tools or a manual data project.

  • 3

    Reporting takes time away from the work

    The more clients you manage, the more time you spend rebuilding similar reports instead of improving their accounts.

See what changed across campaigns and flows.

SendLens brings the main Klaviyo performance metrics into one view, so you can review an account without jumping between reports.

  • Campaign and flow revenue shown separately
  • Week-on-week movement in sends, opens and clicks
  • Subscriber growth and list health
  • Best-performing send days and times
  • Clear comparisons across clients and reporting periods

  • Strong and weak send windows

Cohort analysis

See whether new customers come back.

Group customers by when they first bought, then track how their purchasing changes over time.

This helps you understand which acquisition periods, channels and campaigns produced customers who returned, rather than customers who bought once and disappeared.

  • Retention by acquisition month
  • Second-purchase rates
  • Revenue development over time
  • Side-by-side cohort comparisons
  • Analysis across your full order history
Cohort retention heatmap
Product analysis

SendLens shows the products customers are most likely to purchase next, based on actual order history.

Use it to plan post-purchase journeys and cross-sell campaigns around real buying behaviour.

  • Most common second purchases
  • Frequently purchased product combinations
  • Cross-sell opportunities
  • Product patterns by customer group
  • Findings that can feed into Klaviyo journeys
