Vibe coding for marketing managers in e-commerce.
You own the promo calendar for a store on Shopify or a similar platform, and every campaign you run ends in a discount code, a landing page and an SMS blast. The tension is that the fastest tools to build are the ones that create codes and send messages, and both cost real money the second they misbehave.
What is true about software in e-commerce before you write a prompt.
E-commerce executives have a platform that does most things and a long list of things it does not. Vibe coding fills the list: the returns portal, the wholesale order form, the inventory view, the promotion tool. Every one of them touches orders, customers and money, and every one of them is visible to shoppers or connected to the systems that serve them.
Never store card data yourself
Payment details go through the payment provider and nowhere else. A tool that touches a card number, even briefly, brings PCI obligations the company does not want. The AI will happily build a card form. Do not let it.
Orders and inventory must agree
A tool that updates stock in one place and not the other oversells. A tool that changes an order without telling the platform breaks fulfilment. Integrations need to be two-way and idempotent, or read-only.
Traffic arrives all at once
A promotion tool or a returns page that worked in testing will be hit by thousands on launch day or Black Friday. Hosting, caching and rate limits are part of the build, not an afterthought.
Customer data is personal data
Names, addresses, order history and email. Privacy law applies, deletion requests must be honoured, and marketing consent is a record you have to keep.
What a marketing manager in e-commerce builds first.
01The single-use code generator
A tool that creates a unique code per subscriber or creator through the platform API, with an expiry and a usage cap, so a code leaked to a coupon site cannot be used a thousand times.
02The product finder quiz
Five questions, a recommendation and an add-to-cart button. It reads price and stock live from the platform so it never recommends something that sold out an hour into the campaign.
03The drop and back-in-stock page
A countdown page with a notify-me form that watches inventory and sends the email when stock returns. Cached hard before launch, because for one hour it will be the most visited page you own.
Marketing managers in every industry tend to build the same four things. The marketing manager page has that list.
The SMS tool messages people who never opted in
Your flow tool pulls phone numbers from the order export and sends the launch text to everyone, though half of them ticked only the email box. In the US one unsolicited marketing text can cost $500 to $1,500 under the TCPA, and law firms search for exactly this. A single blast to twenty thousand numbers is a claim larger than the year's revenue, with your name on the send.
The pattern underneath is the one every marketing manager hits: names, emails and phone numbers land in a database with default settings and an admin page with no login. The first person who finds the URL has your entire lead list.
What a safe build in e-commerce usually runs on.
Builds usually sit next to Shopify, BigCommerce or a similar platform, connected through the platform's API with a scoped key, hosted on Vercel or comparable, with Postgres for anything the platform does not store. Payments stay inside the platform or Stripe. Public pages get caching and rate limiting before launch.
What changes for a marketing manager in e-commerce.
A CTO in your corner reads every page and form before it goes public. Where the leads are stored, whether the admin has a login, whether the keys are hidden, whether the tracking respects consent. You ask in chat when something breaks mid-campaign and get an answer the same day. You still ship at campaign speed. You just never have the conversation with legal.

Thirty minutes, free, no card. What you built, what is going on with it, whether we can help.
