What is an ecommerce leads database?
An ecommerce leads database is a list of online stores you can sell to. It shows what each store runs, how big it is and who to contact. Some people call it an ecommerce websites database, an online store database, an ecommerce brands list or merchant data.
TAMI AI builds its ecommerce leads database by reading each store's own website. So every record shows the platform, payment providers, carriers and apps the store uses today, with the people who choose them.

Start with how the store takes money and ships parcels. Then narrow by platform, apps, size and the people you need.

| Buy now, pay later | Which finance options shoppers see | Clearpay: 2,399 stores |
| Shipping carrier | Who delivers the parcels, read from delivery and returns pages. More on the logistics page. | Royal Mail: 44,248 stores |
| Countries it ships to | Where the store sells, read from its delivery page | Ships to Ireland |
| Platform | The software the store runs on | Shopify: 64,218 stores |
| Apps and tech stack | Reviews, returns, email and other tools on the site. See technographic data. | Reviews app installed |
| Website traffic | How many people visit, so you can size the store | Above a monthly floor you set |
| Add to cart | The store sells online today | 273,688 stores |
| Contacts by role | The people who decide, with work email and phone | 842,831 contacts |

How do you build an ecommerce lead list?
This is how to find ecommerce leads in TAMI AI, step by step.
Pick the platform and country
Start with the stores your product plugs into, in the markets you sell to.
Check each store is still trading
Keep only stores with a working add-to-cart today.
Filter by payment provider and carrier
Find the stores on the provider or carrier that matters to you.
Size by traffic
Set a floor on monthly visits, so every store is big enough to buy.
Find the person who decides
Add contacts by role, with verified work emails and direct dials.
Screen and send to your CRM
TAMI AI screens UK phone numbers against the TPS and CTPS. Then send the list to HubSpot or Salesforce.
The result is a list of online stores your team can call this week.
How does TAMI AI find online stores?
TAMI AI uses AI to read the code of every website it scans. For each one, it answers three questions.
Who does it sell to?
Whether the company sells to other businesses, to shoppers, or to both. So you only see the companies that fit what you sell.
Is it active online?
Whether the website is live and selling today. A working add-to-cart means the store is trading.
Does it take payments?
Whether the site takes money online, and which payment providers sit behind its checkout.
Is it legal to use ecommerce contact data in the UK?
Yes, when you source it and use it lawfully. Company data read from public websites holds no personal data. Named contacts do, so UK GDPR asks for a lawful basis, clear sourcing and an easy way to opt out.

Ecommerce leads questions
Try TAMI AI for free
1
How do you find companies using Shopify or Magento?
Filter a store database by platform and country, then keep only the stores that are still trading. In TAMI AI that is one search: pick Shopify or Magento, pick the country, and keep stores with a working add-to-cart.
2
How do you detect an online store's ecommerce tech stack?
For one website, the free TAMI AI Chrome plugin shows the platform, apps, payment providers and carriers while you look at the site. For hundreds of stores, TAMI AI reads each store's own website and records its platform and apps, so you can filter on any of them.
3
How do you find online stores by payment provider or carrier?
TAMI AI reads the checkout for payment providers, and the delivery, returns and FAQ pages for carriers. Pick a provider or a carrier as a filter and you get every store that lists it. How TAMI AI finds online stores in the first place is patented, as explained below.
4
How is TAMI AI different from ZoomInfo and Cognism?
ZoomInfo and Cognism start from the person: names, job titles, emails and phone numbers.
TAMI AI gives you the contacts too, with verified work emails and direct dials. But it starts from the store's website. So you also see what each store runs: its platform, payment providers, carriers, apps and traffic. That is how you find the stores that fit what you sell, before you pick up the phone.
5
Where can I buy an ecommerce leads database?
You can build one in TAMI AI instead of buying a fixed file. Open a free account, search by payment provider, carrier, platform and country, and see the store count before you pay. Prices are on the pricing page.
6
How do I find ecommerce leads?
Pick the platform and country, keep stores with a working add-to-cart, then filter by payment provider, carrier and traffic. Add the people who decide and send the list to your CRM. The six steps above walk through it.
7
How can I tell which ecommerce platform a website uses?
For one site, the free TAMI AI Chrome plugin shows the platform while you browse it. For many sites, filter TAMI AI by platform, and it returns every store it found on that platform.
8
How many Shopify stores are there in the UK?
TAMI AI counted 64,218 UK stores on Shopify with a working add-to-cart on 13 October 2026, counted once per parent company. In the US it counted 256,534.
9
Can I filter online stores by traffic?
Yes. Set a floor or a range for monthly website visits, so your list only holds stores big enough to buy what you sell.
10
Can I find the person who decides at an online store?
Yes. Search by role, such as head of ecommerce or operations director, and TAMI AI returns verified work emails and direct dials. It counted 842,831 contacts at UK online stores on 13 October 2026.
11
What is the best B2B prospect database for retail and ecommerce?
The best one shows the stores that fit what you sell, and the person to call at each. TAMI AI reads 71 million active websites, so you can filter retail and ecommerce companies by platform, payment provider, carrier, apps and traffic.
Free routes work well for a handful of stores. A database is worth it when you need hundreds of stores, sized, with the right person to call.
Find the online stores that fit what you sell
Search by payment provider, carrier, platform and country, and see the count before you pay.
