AppRanks verdict
Generated from live marketplace data — refreshed daily
GMass for Gmail™ is a highly rated Google Workspace app with an established review history. It is listed in the Sales & CRM category on Google Workspace Marketplace, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 6,735 reviews indicate the app has been load-tested at scale across diverse store sizes. Review velocity at scale typically signals broad merchant adoption rather than churn — fast-arriving negative reviews would have pulled the rating down by now if the app's core flows were unstable. The free tier lets you trial the entry feature set without committing a payment method. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical Google Workspace Marketplace listing.
