DEMO Northfold Supply Co. is a fictional store. No email was sent, nothing was pushed to Shopify or Klaviyo, and no offer is real.

Campaign factory demo

A full Black Friday and Cyber Monday campaign for a store that does not exist

Northfold Supply Co. is made up. Its catalog is 16 products in the same shape a Shopify store exposes. The factory took a client brief and that catalog and produced everything on this page: the deals page, 5 emails, the audiences, the send calendar, the Shopify theme code and a QA report.

How it was made

Code does the rendering, the checks and the pushes. The writing is the only part an AI drafts, and QA checks it against the brief.

  1. BriefThe client fills one form: offers, codes, dates, shipping cut-offs, brand. If something is missing the build stops and lists the questions.
  2. CatalogA snapshot of the store's products, prices and stock. Sold-out products are left out of the page and the emails.
  3. PlanSend times in the store's time zone, which offer each email carries, the audiences and the products.
  4. CopySubject lines, preheaders and body copy, written to a schema. Only facts from the brief and catalog may appear.
  5. Build and QAMJML emails, the Shopify section and this preview, then 21 checks: codes, prices, offer windows, links, UTMs, unsubscribe, contrast, phone layout.
  6. Approval, then pushApproval is tied to a hash of the files. Pushes create Klaviyo drafts and an unpublished theme copy. Nothing sends or goes live without a person.

Offers in the brief

Every code, date and price on these pages comes from this table or from the catalog. Times are store time (America/New York).

The emails

Each one is MJML compiled to 600px HTML, with a plain-text version, a preheader, alt text on every image and dark-mode styles. The Klaviyo version keeps the merge tags; these previews swap in sample values. Links here go to the demo deals page; in the real files every store link carries utm_source=klaviyo&utm_medium=email&utm_campaign=demo-northfold-bfcm-2026.
