Know what your competitors change, the week they change it
Your brand competes with stores you know and some you have not found yet. SellWinners shows you who they are, how they advertise and how they email their customers, so your positioning and retention plans rest on what the market is really doing.
What gets in the way
Rivals you have not spotted
New stores open in your category all the time. The one growing fastest may not be on your list yet.
Positioning by guesswork
Price, offer and message are hard to set when all you see of a competitor is its homepage. You need its best sellers, its ads and the angles it keeps repeating.
Retention happens out of sight
Ads are public, but the emails that bring customers back land in private inboxes. Without them, you cannot tell how a rival handles welcome offers, sales or abandoned carts.
The features DTC brands use most
Similar Shops
Enter your own domain and get the shops most similar to yours, each with a similarity score, traffic, growth and active ads. Sort by 30-day growth to put the rising ones on top.
Shop Analytics
See a competitor's best sellers and full catalog, its estimated monthly sales, the apps and theme behind its storefront, its social follower history and the other stores of the same brand.
Brand Tracker
Add your closest competitors once and follow their launches, top ads, headlines and landing pages. A daily record of their ad texts and headlines starts the day you add them, so you can see when a message changed.
Shop Emails
Read every email a competitor has sent, with its monthly sending calendar, its rhythm across the week and the campaign types and promotions it relies on.
Email Library
Browse welcome, abandoned cart and newsletter emails across brands, or filter by an event such as Black Friday, before you plan your own flows and campaigns.

Questions DTC brands ask
Can I start without a card?
Yes. Sign up on the Free plan for the web app, with no card on file: search Shopify stores and the full Meta ad library. Tracking the brands you choose is on paid plans, which you can compare on the pricing page.
Can I see a competitor's sales?
You see estimated monthly sales and their history, next to traffic, growth and best sellers. These are estimates, not figures reported by the store, so they work best for comparing stores and seeing which way each one is moving.
Which plan fits a brand?
It depends on how many competitors you follow and how much you automate. A few tracked rivals checked in the web app need little, while a daily feed into your own dashboards or an AI assistant uses more credits. Paid plans differ in monthly credits, rate limit and API keys.
Can my AI assistant brief me on a competitor?
Yes, on paid plans. Connect it to the MCP server with your API key and ask for a brief on a competitor by name or domain, or for what changed in a tracked brand's ads over the past week. Each tool call costs the results it returns, from your plan's credits.
