Behavioral emails surface the signal. Herald reads it.

Herald will pull Customer.io campaign responses, unsubscribes, and reply intent so the briefing knows which accounts are disengaging from your outbound — before they churn.

What Herald reads

What Herald reads from Customer.io.

  • Email delivery, open, and click events per account

  • Broadcast and trigger campaign reply signals
  • Accounts with no email engagement in 30+ days
Ask anything

Questions you can ask.

  • “Which trial users never opened the welcome sequence?”
  • “Which segment had the lowest click rate on last week's broadcast?”

This week’s briefing

A sample excerpt.

Re-engagement campaign delivered to 41 inactive accounts — 9 opened, 2 clicked, 0 converted to trial restart. Four accounts unsubscribed; two of those have active Stripe subscriptions. The welcome sequence open rate dropped 8pp this week; worth checking the subject line.
