What it does

Sample subheading — replace

Stamped.io is a Shopify-focused reviews, loyalty, and lifecycle marketing platform, positioned as a combined suite rather than a single-purpose reviews app.

The standout is the in-email review collection flow, where a customer submits a star rating and written review directly inside the email itself without clicking through to a separate page. Multiple sources credit this with meaningfully higher response rates than page-based competitors.

Both the free plan and the free trial were eliminated in the 2025 restructure, so a brand can no longer test Stamped before paying. Loyalty is sold as a fully separate $299 a month module from reviews, and features like video reviews, Q&A, and AI sentiment

Who this helps

Sample subheading — replace

• A mid-size or larger Shopify brand ready to commit to a paid plan immediately without needing a free trial to validate fit first

• A brand that wants reviews and loyalty combined under one vendor and can absorb roughly $400 a month for both, especially with the bundle discount

• A team that specifically wants in-email review submission to raise response rates over review-page-based competitors

• Not a good fit for a small or early-stage store that wants to test a reviews app for free first, since Stamped now requires payment before access
