Open Rate

is the percentage of delivered messages that are opened or read by recipients, calculated by dividing the number of message opens by the number of successfully delivered messages. Open rate is a fundamental engagement metric that indicates the effectiveness of the sender's brand recognition, message subject lines or preview text, delivery timing, and overall communication relevance to the audience. Open rates vary dramatically across channels — WhatsApp and SMS typically achieve open rates of 90% or higher within the first few minutes of delivery, while email open rates typically range from 20% to 40% depending on industry and list quality. ConnectGain tracks open rates for all message types and channels, providing the baseline engagement data needed to evaluate campaign effectiveness and benchmark performance improvements over time.
