Increase AOV (2 minute read)
Use Stay’s Product Performance analytics to pick an add-on with strong recurring revenue and low churn.
In ExperienceEngine, create a simple promotion (skip A/B) and set Active.
Turn on Promotion Offer Email (sends after the previous order completes).
1) Choose your add-on
Path: Analytics → Product Performance → Performance
Steps
Identify products with strong recurring revenue and low churn.
Favor widely appealing items (your top performer or a close second).
When possible, choose a trial/single-serve format.
Outcome
You promote something customers actually want, backed by data. Not just guesswork.
2) Create the promotion (keep it simple)
Path: Optimization → ExperienceEngine → New promotion Setup
Name: Clear + searchable (for example, “Add-on · Product Name · First Win”).
Incentive: Percentage or fixed-$ discount.
Type: One-time add-on.
Targeting: Keep broad for your first run; exclude existing owners of the add-on if applicable.
A/B testing: Skip for now to create a clean baseline.
Activate: Toggle Active to go live.
What your customers will see
If the Promotion Offer Email is enabled, they receive it when they become eligible (timed after the prior order completes).
Eligible customers see the add-on offer in the customer portal.
NOTE: Analytics hygiene: If you need major changes later, create a new promotion to preserve clean, comparable analytics.
3) Turn on the Promotion Offer Email
Path: Notifications → Email → Promotion Offer Email → click the Edit icon
Sends automatically after the previous order completes for eligible subscribers.
If you prefer Klaviyo, use the Retextion - Promotion Applied metric per your integration and avoid double-sending by turning off the notification email in Stay.

Your Promotion checklist
At this point, do a quick check to make sure you’re ready to go live.
Promotion created and Active.
Promotion Offer Email toggled On (or your Klaviyo flow is ready).
Quick QA: With an internal/test subscription that doesn’t include the add-on, confirm (a) the portal shows the offer and (b) the email arrives when the subscription becomes eligible (after prior order completion).
4) Measure Success
Path: Optimization → ExperienceEngine → [ select Your Promo] → Details
Use the ExperienceEngine analytics page to measure these KPIs:
KPI | What it tells you |
Offered Experience | How many subscriptions were shown the offer (your reach/targeting size). |
Accepted Experience | How many subscriptions accepted the offer (raw uptake volume). |
Acceptance Rate (Accepted ÷ Offered) | Offer effectiveness when shown; improves with the right add-on and incentive. |
Orders Completed (Accepted) | How many accepted subscriptions completed their next order; confirms the accepted add-on actually transacted. |
Percent Completed (Accepted) | Completion rate for the accepted cohort; highlights operational follow-through after acceptance. |
Total Order Revenue (Accepted) | Dollar impact from completed orders in the accepted cohort. |
AOV (Accepted) (Total Order Revenue ÷ Orders Completed — Accepted) | Average order value for customers who accepted; compare against Declined to confirm the add-on is accretive. |
Orders Completed (Declined) | Baseline orders for those who declined; used for side-by-side comparisons. |
Percent Completed (Declined) | Completion rate for the declined cohort; helps isolate offer effect vs operations. |
Total Order Revenue (Declined) | Dollar impact from completed orders in the declined cohort. |
AOV (Declined) (Total Order Revenue ÷ Orders Completed — Declined) | Baseline AOV to benchmark against Accepted. |
Additional Revenue from Experience | Revenue specifically attributed to the products tied to the accepted experience (direct uplift). |
Subscriptions Active / Paused / Cancelled after Order (Accepted) | Post-order subscription health for those who accepted; watch for unintended churn/pauses. |
Subscriptions Active / Paused / Cancelled after Order (Declined) | Post-order health for those who declined; compare to Accepted to assess retention impact. |
What comes next?
If Acceptance Rate isn't what you want it to be, reconsider the add-on or the incentive.
If AOV is boosted but cancellations tick up, then switch to a different product.
