Email Capture Shopify Apps — Frequently Asked Questions
1. Which email capture app has the highest market share on Shopify?
Klaviyo: Email Marketing & SMS ranks #1 by share among email capture apps at 50.5%, 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 email capture Shopify apps?
For email capture (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.
3. Which email capture apps are gaining market share on Shopify?
Klaviyo: Email Marketing & SMS is gaining email capture app market share fastest this month, up +25.94pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.

6. How many email capture apps does ShopDigest track on Shopify?
ShopDigest tracks 96 email capture 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 email capture app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under email capture (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 email capture, Klaviyo: Email Marketing & SMS leads on share; see the rankings tab for who currently holds #1 position.
