Google Analytics helps you move on from numbers that don't matter (like open rates, click throughs) and focus on what matters - money donated to your end cause, and how you can attract more of it.
Add your GA Measurement ID in Beacon and hey presto: Your donations and memberships will show up as beautiful conversions in Google Analytics.
Now it's easy to see which marketing channels drive the most revenue, which emails are the most successful at driving donations and which Google ads provide the best ROI.
