Open Rate

Definitions

1. The percentage of delivered emails that are opened by recipients, used as a rough engagement metric in email marketing. Open-rate interpretation has become less reliable as privacy protections changed tracking behavior.

   In plain English: The share of delivered emails that people open.

   Example: "The subject line boosted open rate, but click-through stayed flat."
