Sender Email Shopify Apps – Analytics & Insights

Sender Email Marketing & SMS ranks #1 for sender email with 2.1% share — the leader position in a fragmented field where many apps are within striking distance, -55.0pp ahead of MS Order Printer ‑ PDF Invoice (57.1%). GST Pro: GST Invoice India sits at #3 with 15.0% share, rounding out the top tier. Together, the top 3 apps absorb 74.2% of all sender email installs — a highly concentrated landscape with limited room for new entrants. Lexware Office (lexoffice) 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.

India is the largest single market for sender email apps at 23.3% — but no country dominates, meaning sender email apps serve a globally distributed merchant base. United States follows at 12.4%, with Australia at 9.6%. Together, the top 3 markets account for 45.2% of sender email app installs worldwide. France (8.0%) and United Kingdom (7.2%) round out the top 5.
