How can I compare the success of two different sending domains in Gmail?

Summary

Comparing the success of different sending domains in Gmail involves a multi-faceted approach that includes leveraging existing reporting tools, A/B testing, and monitoring domain reputation. Key metrics such as open rates, click-through rates, bounce rates, spam complaints, and unsubscribes should be tracked. Google Workspace Admin Help and Google Postmaster Tools can provide insights into domain health and authentication status. Proper email authentication (SPF, DKIM, DMARC) is crucial, and ensuring comparable sending volume and separating traffic types (transactional vs. marketing) across domains are vital for accurate analysis. Analyzing data in tools like Excel, Google Sheets, and Google Analytics using UTM parameters is also recommended. Finally, considering factors such as domain age and identifying any blacklistings that may affect deliverability is important.

Key findings

  • Leverage Reporting: Utilize existing reporting tools or export data to Excel/Google Sheets for side-by-side comparison of metrics.
  • A/B Testing: Employ A/B testing to determine which sending domain yields better engagement and deliverability.
  • Monitor Reputation: Track sender reputation, identify blacklistings, and use tools like Google Postmaster Tools for insights.
  • Ensure Authentication: Implement SPF, DKIM, and DMARC to ensure proper email authentication and improve deliverability.
  • Analyze in Analytics: Use UTM parameters to track email performance in Google Analytics.

Key considerations

  • Comparable Sending: Ensure both domains have similar sending volume and history to Gmail users for a fair comparison.
  • Traffic Separation: Separate traffic types (transactional vs. marketing) across domains for more accurate monitoring.
  • Domain Age: Consider domain age as it can influence domain reputation and deliverability.
  • Blacklist Checks: Regularly check for and address any blacklistings that might affect deliverability.
  • Goal Setting: Set clear goals and use tracking metrics (opens, clicks, replies, bounces, spam complaints) to measure the domains performance.
