Summary
Monitoring email deliverability trends involves a multifaceted approach encompassing technical aspects, engagement metrics, and sender reputation. Key technical KPIs include bounce rates, SMTP error codes, and the implementation of SPF, DKIM, and DMARC. Sender reputation is tracked through spam complaints, blocklist status, and feedback loops, with tools like Google Postmaster Tools and Microsoft SNDS providing valuable insights. Engagement metrics, such as open rates, click-through rates, and conversion rates, offer a view of subscriber interaction, segmented by device and ISP. List hygiene, including managing hard bounces and unengaged subscribers, is critical. Analyzing data over time, rather than relying on one-day numbers, is essential for identifying meaningful trends. Indirect indicators like sudden unsubscribe spikes or low conversion rates can signal deliverability issues. Placement rates, representing emails reaching the inbox versus spam, are a direct measure of success. Actively monitoring and addressing complaints and continuously checking blocklist status are recommended for maintaining a healthy sending reputation. The Apple privacy changes don't impact the validity of trend analysis.
