Both CWILL Popup Email Marketing and SOPO Conversions offer a free plan. CWILL Popup Email Marketing lists no paid plan with a published price; SOPO Conversions lists no paid plan with a published price. Prices are as listed on the Shopify App Store; check what each tier includes in the Pricing section above.
CWILL Popup Email Marketing (4.9★, 7,667 reviews) and SOPO Conversions (5.0★, 6 reviews) are essentially tied on rating. Look at review velocity and individual reviewer quotes — both visible on each app's detail page — to differentiate.
SOPO Conversions holds the higher average rating (5.0★ vs 4.9★). That is the one dimension AppRanks can separate them on here — read both apps' detail pages for the feature breakdown and recent listing changes.
Both apps are one-click installs from the Shopify App Store. AppRanks doesn't measure setup time directly; CWILL Popup Email Marketing has more published reviews to read for user-reported install experience (7,667 vs 6).
AppRanks cannot say which fits a larger or smaller operation — there is no store-size measurement in the Shopify App Store data. What it can show: CWILL Popup Email Marketing has 7,667 published reviews; SOPO Conversions has 6 published reviews. Compare plan limits and pricing tiers against your own volume.
Migration support varies by app and category. CWILL Popup Email Marketing and SOPO Conversions both publish their export options on their marketplace listing pages (or in their support docs); some apps offer one-click import from competitors, others require CSV. The fastest check: search "import from SOPO Conversions" in each app's help center. AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.
