Quick answer: Helium 10's Follow-Up sends Amazon's official review request, but it's bundled into a research-and-launch suite priced from roughly $39/month up past $250, with the useful tiers well over $100. EcomSanity does compliant, fully-covered review automation plus operational analytics for $9.90/month, with a 250-request free tier. If review requests are the goal, Helium 10 is an expensive way to get there.
Helium 10 is a strong product for what it's built for. Review automation just isn't what it's built for — it's a checkbox on a much larger, more expensive tool.
What Helium 10 is actually for
Helium 10 is a product-research and growth platform: Cerebro and Magnet for keywords, Black Box for product ideas, listing optimization, rank tracking, an advertising module, and Follow-Up for post-purchase messaging and review requests. The reason to buy Helium 10 is the research ecosystem — Helium 10 vs Jungle Scout covers that comparison.
Follow-Up can send Amazon's official Request a Review for eligible orders, and it can build custom buyer-seller message sequences — though the compliant, low-risk path is the official call only, per what's allowed in review automation.
The price problem
Helium 10's plans are priced for the research suite. The entry tier sits around $39/month with tight limits; the tier most sellers actually use runs well over $100/month, and higher plans go past $250. That's reasonable value if you're using Cerebro, Black Box, rank tracking, and the rest. If you're logging in only for Follow-Up, you're paying suite prices for one module.
EcomSanity's review automation is included on the free plan (250 official requests a month) and the $9.90/month Pro plan (5,000 requests, plus solicitation history, marketplace filtering, and notifications). The gap is an order of magnitude.
What you're not getting from Follow-Up
Helium 10 is oriented toward finding and launching products. It's thinner on the daily job of running an established catalog. EcomSanity is built for that side:
- Sales velocity across rolling windows and days of stock net of inbound and reserved units.
- Session-weighted Buy Box percentage and conversion per ASIN, so a listing losing the box on real traffic surfaces before it dents revenue.
- Return rates with reasons and dispositions; aged-inventory surcharge risk; category sales.
If your catalog is set and your weekly questions are about restock, Buy Box, and returns rather than your next product, that's the toolset that matters — and Follow-Up doesn't provide it.
The comparison
| EcomSanity | Helium 10 (Follow-Up) | |
|---|---|---|
| Official Request a Review | Yes | Yes |
| Compliant-by-default (no custom pitch) | Yes | Custom sequences available (higher risk) |
| Operational analytics (velocity, stock, Buy Box, returns) | Yes | Limited |
| Product & keyword research | No | Yes, the core strength |
| Free tier for review requests | 250/month | Trial only |
| Entry price for the review feature | $9.90/month | $100+/month effective |
Which to choose
Choose Helium 10 if you're actively researching and launching products and will genuinely use Cerebro, Black Box, and the rest — Follow-Up then comes along for free, and running one login is convenient.
Choose EcomSanity if you're operating an existing catalog and want compliant, fully-covered review requests plus the inventory, Buy Box, and return analytics that keep it healthy — without paying a research suite's monthly price for a feature you'd use a slice of. If you do need research tools too, it's cheaper to run EcomSanity for operations and add a research tool only during active launch phases. See best Amazon review request software for the full field.
EcomSanity sends Amazon's official Request a Review for every eligible order through SP-API authorization, alongside the operational analytics a research suite doesn't focus on — at $9.90/month, or free for up to 250 requests.
Frequently asked questions
Does Helium 10 do Amazon review requests?
Yes, through its Follow-Up feature, which can trigger Amazon's official Request a Review for eligible orders. It's one module inside Helium 10's broader platform of research, keyword, listing, and advertising tools.
Is Helium 10 worth it just for review automation?
Usually not. Helium 10's value is the research and listing ecosystem, and its plans are priced for that — a mid-tier plan runs well over $100/month. If you only need compliant review requests, a focused tool at a fraction of the price does the same job.
What does EcomSanity offer that Helium 10's Follow-Up doesn't?
Operational analytics for an existing catalog: sales velocity, days of stock, session-weighted Buy Box and conversion, and return-rate analysis, alongside the review automation. Helium 10 is oriented toward finding and launching products rather than running the ones you have.
