Stop the multi-channel budget leak.
Master your Reachability Economics.

You're sending Emails AND SMS AND WhatsApp messages to the same users. It's not "omni-channel marketing"—it's expensive noise that drives unsubscribes.

The Old Way: Expensive Redundancy

  • ❌ Sending $0.05 SMS to users who open $0.0001 emails
  • ❌ Joining logs manually with broken VLOOKUPs
  • ❌ High burn rate from WhatsApp & SMS over-saturation

The New Way: Suppression Logic

  • ✅ Identify the one channel with the highest ROI per user
  • ✅ Suppress expensive channels for "Email-First" segments
  • ✅ 100% data join accuracy (Sends + Opens + Clicks)

How to fix your reachability mapping

  1. Upload your Sends CSV. Export the log of every channel touched for every user.
  2. Upload your Engagement CSV. Drop in the corresponding opens and clicks.
  3. Download the Suppression List. Get a clean matrix telling you exactly which channels to turn off for which users to maximize margin.

Frequently Asked Questions

"Is my data leaving my computer?"

No. The entire correlation engine runs in your browser. It's completely static. We couldn't look at your customer data even if we tried.

"Why do you need two different files?"

Marketing platforms (like Klaviyo or Clevertap) export "sends" and "engagements" as entirely separate activity logs. We built this tool to automatically join them so you don't have to wrestle with 500,000-row VLOOKUPs and pivot tables in Excel.

"What does Confidence Score mean?"

It measures how reliable our recommendation is. It balances the user's raw engagement rate with the total number of times they've been contacted, ensuring recommendations aren't skewed by a lucky single interaction.
