Declining open rates are a common challenge that can be fixed with the right diagnosis and strategy.
Apple's Mail Privacy Protection inflated open rates initially, and now adjustments are needed for accurate measurement.
List hygiene is critical — removing unengaged subscribers improves deliverability for your active audience.
Authentication setup (SPF, DKIM, DMARC) ensures your emails reach inboxes instead of spam folders.
Subject line optimization, send time testing, and segmentation are ongoing practices for healthy open rates.
