Upsell Emails Shopify Apps — Frequently Asked Questions
1. Which upsell emails app has the highest market share on Shopify?
Shopify Flow ranks #1 by share among upsell emails apps at 80.0%, but the market is fragmented — multiple apps capture meaningful share. Compare the top 5 on features and pricing before deciding.
2. How is market share calculated for upsell emails Shopify apps?
For upsell emails (a keyword page), market share is rank-weighted — apps at position #1 carry roughly 40× the weight of apps at position #22, and apps beyond #22 are excluded. Each app's weighted score is divided by the total weighted score across the keyword to give the share %. This reflects Shopify search behaviour: most installs come from the top of the results.

6. How many upsell emails apps does ShopDigest track on Shopify?
ShopDigest tracks 96 upsell emails apps on the Shopify App Store. Market share, rankings, and review data refresh weekly so you can track competitive shifts as they happen.
7. Why does the highest-share upsell emails app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under upsell emails (driven by Shopify's own algorithm), while market share on ShopDigest is estimated from review counts and other factors as a proxy for active installs. The two metrics move on independent dynamics, so the highest-share app and the #1-ranked app are not always the same — and a divergence between them is worth noting rather than assuming one will pull the other along. For upsell emails, Shopify Flow leads on share; see the rankings tab for who currently holds #1 position.
