Cross-Sell Emails Shopify Apps – Analytics & Insights

Klaviyo: Email Marketing & SMS ranks #1 for cross-sell emails with 19.4% share — the leader position in a fragmented field where many apps are within striking distance, -56.7pp ahead of Shopify Flow (76.1%). Brevo PushOwl: Email,Push,SMS sits at #3 with 2.3% share, rounding out the top tier. Together, the top 3 apps absorb 97.8% of all cross-sell emails installs — a highly concentrated landscape with limited room for new entrants. Seguno Email Marketing is the standout mover this month, climbing 7 positions — a momentum signal worth tracking. Worth noting: the top-ranked app and the highest-share app aren't the same here — App Store rank and our market share metric (computed from review counts and other factors) move on independent dynamics, so cross-checking both views matters in this category.

With this many viable apps, pricing model and integration depth differentiate cross-sell emails options more than rank does.

1 app on this chart hasn't yet crossed 1,000 reviews: Wiz ‑ AI Email Marketing at 197 cumulative reviews. Wiz ‑ AI Email Marketing is closest to the milestone — its current count puts it roughly 20% of the way to 1,000.

The 63-month gap between Shopify Flow's and Klaviyo: Email Marketing & SMS's time-to-1,000 highlights how unevenly product-market fit landed across this cross-sell emails set — the leader found its merchant audience early, while late-rampers took multiple years to reach the same review depth. For merchants comparing these apps today, slower-ramping apps may have closed the functionality gap but still operate on smaller review bases.
