What are the best tools for tracking all-round email deliverability?

Summary

Tracking email deliverability effectively requires a multi-faceted approach that combines various tools, strategies, and a deep understanding of sending behavior. Many recommend starting with a spreadsheet to track key campaign metrics (bounces, complaints, sends, clicks) and match them to a content calendar. Monitoring sender reputation using Google Postmaster Tools and Microsoft SNDS is essential, along with seed list testing to evaluate inbox placement across different ISPs. Dedicated platforms like Validity's Everest, Litmus, Mailjet, SendGrid, and SparkPost provide comprehensive features for sender reputation monitoring, email testing, and list hygiene. Implementing email authentication protocols (SPF, DKIM, DMARC) and regularly cleaning email lists are also crucial. Furthermore, it is important to look beyond inbox placement and focus on feedback loops and complaint rates. Tools like MXToolbox can help diagnose server health and check blocklists. Avoid solely reacting to tool alerts; proactively use them to gain deeper insights. While GlockApps is mentioned, there are also warnings about the accuracy of its seed list.
