Review collection is a funnel like any other, and funnels are fixed one step at a time. Two cards in Analytics show you exactly where yours leaks: the collection funnel and email performance.
Read the funnel
The Collection funnel card tracks four steps, each with its count and its share of the top:
Emails sent. Requests that left the building.
Emails opened. Subject line and sender did their job.
Forms started. The click landed on your review form.
Forms completed. A review came home.

Fix the step that leaks
Sent is low. Your engine is idle. Check the trigger and delay in Collect & publish, and confirm orders are flowing in the Requests queue.
Opens are low. Subject line and sender problem. Test a plainer subject in the email editor, send from your own domain, and check timing: a request landing three weeks after delivery opens poorly.
Starts are low. The email body is not selling the click. Lead with the ask, mention the reward if you offer one, and keep one clear button.
Completions are low. The form is asking too much. Trim optional fields, keep a small minimum length, and remember every extra question costs completions.
Email performance
The Email performance card pairs a daily chart of emails sent against reviews collected with your three deliverability rates: delivery, open, and click. The chart's gap between the two lines is your funnel drawn over time. The rates tell you whether a slump is a deliverability problem (delivery rate sliding), a content problem (opens fine, clicks down), or a volume problem (the sent line itself is flat).
š” Tip: The cheapest wins, in order: turn the reminder on, trigger on fulfillment or delivery rather than purchase, and attach a media reward. Each lifts a different funnel step, which is why they stack so well.
