Email is one of the highest-ROI channels, but only if you can tell which issues actually drive sales. By default, email clicks hide their source and land in Direct/None.
Why this matters
Your list is an asset. Knowing revenue per issue tells you which subject lines, offers, and topics convert, so every send gets better, and you can prove the list is worth growing.
Why most analytics tools can't tell you
Email opens in a browser with no referrer, so analytics tools can't see the click came from your newsletter. You get a "Direct" blob with no issue-level detail.
How DataFast does it
DataFast reads tracking parameters and attributes revenue per link. Add UTM tags (most email tools do it automatically) and each issue becomes measurable.
How to do it
Simple:
https://yoursite.com/?ref=newsletter
Per issue:
https://yoursite.com/?utm_source=newsletter&utm_medium=email&utm_campaign=issue-042
Then check the Source card for total newsletter revenue and the Campaigns tab for revenue per issue in your dashboard.
Beehiiv, Kit, and Substack can auto-append UTMs to every link, set it once and every issue is tracked.
