What is Open Rate?

Quick Answer

The percentage of delivered emails that were opened by recipients.

Open rate = (unique opens / delivered emails) × 100. Average open rates range from 15-25% depending on industry. Apple Mail Privacy Protection (MPP) inflates open rates by pre-loading tracking pixels. MisarMail accounts for MPP and shows adjusted open metrics. Improve open rates with compelling subject lines, send-time optimization, and list segmentation.
