AppRanks verdict
Generated from live marketplace data — refreshed daily
Mailrelay is a well-rated WordPress app with a limited review volume. It is listed in the Newsletter category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 5 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.
