RedHen Labs vs m19
Built to "let the AI run" — plus 3% of managed ad spend. Here's how they compare for Amazon PPC management.
m19 review, from a competitor: what it does well, and where we differ
m19 is an automated Amazon PPC platform that invites you to "let the AI run." Its pricing page lists Autopilot at a fixed $59 a month, which it recommends for sellers and vendors under $5K of ad spend a month, and Professional at "$479 + 3%" of managed ad spend, with a 30-day free trial. Autopilot, for Sponsored Products only, costs less than we do, and we will say so. On Professional, the 3% grows with every dollar you advertise: at $25,000 a month, it is $1,229.
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.

What 3% costs as you scale
m19's Professional plan is $479 a month plus 3% of managed ad spend. At $10,000 a month in ad spend that is $779; at $25,000, $1,229; at $50,000, $1,979. RedHen Labs is $129 at every one of those — $1,100 a month less at $25,000.
Letting the AI run, or checking it first
m19 invites you to "let the AI run." Our default is the opposite: the AI proposes and you approve, so you see every change before it reaches Amazon, and any automation you've learned to trust can be switched to run on its own.
When m19 is the better pick
m19's Autopilot plan is a fixed $59 a month — $10 less than our Growth plan, and less than half Professional — for Sponsored Products, on campaigns it builds itself; m19 recommends it under $5K a month in ad spend. If you're at that size and want hands-off automation, it's the cheaper choice.
What you’d pay at your ad spend
| Monthly ad spend | m19 (Professional) | RedHen (Professional) | With RedHen, a month | With RedHen, a year |
|---|---|---|---|---|
| $5,000 | $629 | $129 | $500 less | $6,000 less |
| $10,000 | $779 | $129 | $650 less | $7,800 less |
| $25,000 | $1,229 | $129 | $1,100 less | $13,200 less |
| $50,000 | $1,979 | $129 | $1,850 less | $22,200 less |
What each includes. m19: Professional has machine-learning bid optimization and keyword discovery on the campaign structure m19 builds itself, across Sponsored Products, Brands, Display and DSP, with dayparting, TACOS targeting and a profit and loss report. 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. Professional is "$479* + 3% / Month" "of managed ad spend, excl. VAT": $479 + 3% of managed ad spend, with no threshold (in Japan, $229 + 3%). Autopilot, for Sponsored Products only, is a fixed $59 a month at any spend. Ad spend means the spend the tool manages. Source: m19.com, 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
m19 calls itself "a machine learning platform, not a rule-based system," and it "creates its own campaign structure." RedHen Labs works on the campaigns you already run, with rules you set and AI suggestions you approve.
- 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.

Do I have to turn off m19's autopilot first?
On any campaign you want RedHen Labs to manage, yes. Two tools bidding on the same keyword just keep undoing each other's work. Connecting itself changes nothing: it reads your data, and by default every change waits for your approval and is logged with a one-click undo.
Should I "let the AI run" my Amazon ads?
That's m19's pitch: "let the AI run." Ours is the opposite. Left untethered, AI is bad at Amazon PPC: it chases the target it's given, and a mistake on autopilot repeats every day until someone catches it. In RedHen Labs, AI is only one of the tools, with rules, harvesting, dayparting and budget automations. It assists the operator; it doesn't decide for you. It proposes, you approve.
When is m19 the better pick?
m19's Autopilot plan is a fixed $59 a month, $10 less than our Growth plan, for Sponsored Products on campaigns it builds itself; m19 recommends it under $5K a month in ad spend. If you're at that size and want hands-off automation, it's the cheaper choice. Its free trial is longer too: 30 days to our 14.
