RedHen Labs vs SellerMate.ai
Cheap to start — then 1.5% of ad spend on Unlimited. Here's how they compare for Amazon PPC management.
SellerMate.ai review, from a competitor: what it does well, and where we differ
SellerMate.ai starts cheap: a free plan, and Pro at $29 a month ($20 billed annually) with a monthly credit allowance. Its Unlimited plan is $150 a month ($105 billed annually) "Or 1.5% of monthly ad spend, whichever is higher" — so above $10,000 a month in ad spend, the percentage sets the bill: $375 at $25,000. Its AI agent asks first — "Nothing executes until you click to confirm" — while Pro's "Bids, budgets & bulk edits on autopilot." RedHen Labs is $129 a month flat, and every automation starts in an approval queue.
RedHen Labs is a focused Amazon advertising management platform with built-in profitability tracking. At a flat $19 to $129 a month — never a percentage of ad spend — it gives mid-tier sellers the automation and visibility that used to require enterprise tools or agencies.

Cheap until the percentage takes over
SellerMate's Pro plan is $29 a month, but Unlimited is $150 a month or 1.5% of monthly ad spend, whichever is higher. Above $10,000 a month the percentage decides: $375 at $25,000, $750 at $50,000. RedHen Labs stays at $129.
Two answers to who decides
SellerMate's AI agent asks first — "Nothing executes until you click to confirm" — while its Pro plan lists "Bids, budgets & bulk edits on autopilot." RedHen Labs uses one rule for both: changes wait for your approval unless you switch a specific automation to run on its own.
When SellerMate is the better pick
If a credit-based AI agent at $29 a month covers what you need, SellerMate's Pro plan costs far less than ours.

What each includes. SellerMate.ai: Unlimited has unmetered automation runs — rules for bids, budgets, dayparting, search-term harvesting and inventory — on unlimited ad accounts, with hourly data and an AI agent whose changes wait for you to confirm. RedHen Labs Professional: everything in Growth, plus the rule engine — bid rules, keyword harvesting and negative keyword automation, budget and placement automations, dayparting — and the plain-English AI assistant.
How it’s calculated. Unlimited is $150 a month billed monthly "Or 1.5% of monthly ad spend, whichever is higher", counted on total ad spend across your connected accounts. Billed yearly its flat fee is $105; how the 1.5% works on yearly billing isn't published. Pro, at $29 a month, runs automation on 5,000 credits a month, at 50 credits a run. Ad spend means the spend the tool manages. Source: sellermate.ai, checked October 31, 2026. RedHen’s figure is the Professional plan’s monthly price, the same at any ad spend ($110.08 a month billed yearly). AI assistant: $20 of usage included each month, and it stops at $50 unless you raise the limit.

How RedHen is different
SellerMate's AI agent asks first — "Nothing executes until you click to confirm" — while its rules run on autopilot. RedHen Labs queues both by default, and you choose which run on their own.
- Rules first, AI as the advisor. Rules settle the clear-cut calls, and the AI suggests changes inside hard limits. Auto-apply is off by default; switched on, the AI can only nudge bids.
- It waits when the data is thin. RedHen won’t cut a bid on too little data. It looks again next cycle instead of guessing.
- The same flat fee at any spend. $19, $69 or $129 a month, whatever you spend on ads.
- You approve, and one click undoes it. Changes wait for your approval unless you choose otherwise, and each one is logged with a one-click undo.
Why we don’t charge more
We could charge more. We don’t, and it isn’t because this is a lighter product — it’s because it’s a focused one. We built the things an Amazon seller actually touches every week and left out the twenty modules that pad a suite. A focused product costs less to build and less to run, so it can cost less to buy.
The other reason is simpler. By the time a seller has paid referral fees, fulfillment, storage, returns, and advertising, a lot of hands have already been in the till — and then an agency wants a percentage of sales and a tool wants a percentage of spend. The person who designed the product, paid for the inventory, and carries every bit of the risk ends up with the thinnest slice of it. We decided not to be one more toll on that road. $129 is a number we can hold at any account size, which means growing your business never costs you more to keep using ours.
