Klaviyo setup for fashion brands
Fashion moves quickly: new collections arrive, sizes sell out and prices change. A Klaviyo setup for a fashion brand can respond to that. Klaviyo's help lists price drop and low inventory among its flow triggers, which suit alerts for items people viewed. Campaigns for new arrivals can go to segments by style or category. Post-purchase flows need to account for returns, which Klaviyo's Shopify data reference records as Refunded Order, so customers who sent something back are not asked to review it. Product content in emails should show sizes and fit clearly, and measurement should look at orders kept, not only orders placed.
This page covers new arrivals, price and stock flows, size-aware content, returns, segments and measurement. LetGetGrow sets up and manages Klaviyo and Mailchimp, including flows, templates, integrations and migrations, with the scope, cost and timeline set out in a custom quotation.

Fashion flows
| Flow | Trigger | Purpose |
|---|---|---|
| Price drop | Price falls on a viewed item | Timely alert |
| Low stock | Inventory runs low | Prompt before sizes sell out |
| Abandoned checkout | Checkout Started without order | Recover the order |
| Post-purchase | Placed Order, Fulfilled Order | Styling tips, care, review |
| Returns handling | Refunded Order | Exclude from review and upsell |
New arrivals
New collections are a natural reason to email. Send to segments that fit: buyers of a category, people who browsed similar items or customers who bought from a previous collection. Show the pieces on people with clear sizing information, and link to the right product pages.
Returns in flows
Returns are part of fashion. A customer who returned an item should not receive a review request or an upsell for it. Use the Refunded Order event to exit or filter post-purchase flows, and test with a refunded test order.

Example: a knitwear label
Illustrative example — not a client case study
Situation: A knitwear label releases small batches that sell out by size.
- A low stock flow alerts people who viewed a jumper when their likely sizes are running low.
- The post-purchase flow sends care instructions after delivery and skips anyone with Refunded Order.
- Monthly reports compare email-attributed orders with orders kept after returns.
What this shows: Emails respected returns and helped customers buy before sizes sold out. This example is illustrative.

Style segments
Segments by category bought, price range or collection let campaigns reach people likely to want each launch. Klaviyo's segments are dynamic, so customers move as their buying changes.
Consent
Price drop, low stock and new arrival emails are marketing. Send them only to people who agreed or meet the soft opt-in conditions under ICO guidance.
Sizes in alerts
A low stock alert is only useful if the sizes the customer wants are still available. Where possible, note a customer's usual size from past orders and check alerts reflect real availability. Linking straight to the product page with sizes visible saves frustration.
Trusted sending
Set up a branded sending domain and confirm authentication meets Gmail's sender guidelines before sending launch campaigns at volume.
How often to email
Frequent launches can tempt frequent sends. Use segments so each customer hears about collections likely to interest them, and watch unsubscribe and complaint rates as frequency rises.
Styling content
Post-purchase emails showing how to wear or care for a piece can reduce returns and build loyalty. Match the content to what was ordered, using product data from the order event.
Restocks
Popular pieces that sold out may return. Collecting interest on the product page and emailing those people when stock returns, with their consent, can recover sales that would otherwise be lost to a competitor. Check that stock data reaches Klaviyo accurately before relying on it.
Lookbooks and styling
Campaigns that show how pieces work together, across a range of people and sizes, can help customers picture items and choose sizes with confidence. Link each item to its product page and check the links before sending.
New and repeat customers
Loyal customers may buy each collection anyway. Report new and repeat customers separately so you can see what email adds, and use a welcome series to turn first-time buyers into regulars.
