An Apple bug was causing Substack writers to panic.
Some saw a lower-than-usual email open rate beginning July 24th — which Substack tied to last weekend’s iCloud Private Relay outage.
With Private Relay, user data is routed through multiple servers, increasing privacy but possibly counting each open more than once. In other words: what newsletter writers saw is a more accurate number.
