Quick answer: Both send Amazon's official Request a Review compliantly. FeedbackFive adds deep review monitoring, alerting, and reputation reporting and prices accordingly, starting around $34/month. EcomSanity folds the request automation into a full operations console — sales, inventory, Buy Box, returns — at $9.90/month with a 250-request free tier. Pick FeedbackFive if monitoring is the point; pick EcomSanity if requests are one job among several.
FeedbackFive, from eComEngine, is one of the long-standing names in Amazon review software. It's a genuinely capable specialist. The question is whether you need a specialist.
Where they agree
Both tools do the compliant core correctly: they use Amazon's official Request a Review workflow, respect the 5–30 day window, prevent duplicate sends, and keep a history of what went out. Neither offers custom review-pitch messaging or incentive workflows, because those aren't compliant — what's allowed in review automation covers why.
If your only requirement is "send the official request for every eligible order without missing any," both meet it.
Where FeedbackFive is stronger
FeedbackFive is built around the full review lifecycle, not just the request:
- Review monitoring: alerts when any product gets a new review, with sentiment and star rating, across your whole catalog.
- Negative review workflows: flags critical reviews quickly so a brand team can respond through permitted channels or address the underlying product issue.
- Reputation reporting: trend reports on review velocity, average rating over time, and feedback score, formatted for sharing with a brand or leadership team.
- Listing and Buy Box alerts as add-ons.
For a brand with a large catalog where a single 1-star on a hero SKU is a fire drill, that monitoring layer is worth paying for.
Where EcomSanity is stronger
EcomSanity treats the review request as one instrument on a wider panel. Alongside compliant, fully-covered request automation, you get:
- Sales velocity and days of stock per SKU, so restock risk surfaces in the same place.
- Session-weighted Buy Box percentage and conversion per ASIN — catching a listing quietly losing the box.
- Return rates with reasons and dispositions, and aged-inventory risk.
- Category-level sales analysis.
And it's cheaper. The free plan includes 250 official review requests a month plus the order-metrics dashboard. Pro is $9.90/month for 5,000 requests, solicitation history, marketplace filtering, and email notifications. FeedbackFive starts around $34/month for a limited order volume and rises with order count and monitoring add-ons.
For a seller who wants review requests handled and wants one place to see whether inventory, Buy Box, or returns need attention, EcomSanity covers more of the actual weekly job for less.

Which to choose
Choose FeedbackFive if review and feedback management is the job: large catalog, brand team, a need for fast alerts on every new review and formal reputation reporting.
Choose EcomSanity if review requests are one task among many and you'd rather not run — or pay for — a dedicated review platform on top of everything else. You get compliant, fully-covered requests plus the operational signals (inventory, Buy Box, returns, velocity) that a review specialist doesn't touch, at roughly a quarter of the entry price. For the wider tool landscape, see best Amazon review request software.
EcomSanity connects through official SP-API authorization and sends Amazon's Request a Review for every eligible order, inside a console that also tracks the inventory, Buy Box, and return signals a review-only tool leaves out. The free plan covers 250 requests a month.
