WHY SPORTS IS DIFFERENT

Sports gear is bought on fit and timing, and both drive returns.

Shoes and athletic wear have to fit exactly and often have to arrive before a game, a race, or a season, so sizing and delays both send orders back.

Fit sends it back

Sizing is the top return reason in footwear and athletic wear. When the size runs off, most brands hand back a refund and lose the customer and the sale in one step.

Drops and seasons spike WISMO

Sports runs on hyped launches, team seasons, and event deadlines. Each one floods support with "where is my order" tickets, right when your team has the least room.
20–40%
of online footwear and apparel orders are returned, among the highest in retail.
most
of sportswear returns are driven by fit and sizing.
20–65%
of an item's value can be lost to processing a single return.

HOW CLICKPOST HELPS

Own the whole journey from
doorstep to the way back
ClickPost runs tracking, returns, exchanges, and carrier decisions from one platform, so every post-purchase moment works for retention instead of against it.

Keep shoppers on your brand, not the carrier's site

Proactive updates by email and SMS at every milestone, plus a branded tracking page that looks like your store. Fewer "where is my order" tickets during drops and seasons.
  • Mobile-first branded tracking page
  • Milestone alerts by email, SMS, and push
  • Estimated delivery dates that set expectations

Use case

An athletic brand sends proactive SMS at every milestone during a sneaker drop, keeping shoppers on a branded page instead of the carrier site.

Business impact

Up to 60% lower WISMO queries and higher engagement on the brand's own domain.
Frame 2147228189 (1)

Turn a return into the next size, not a refund

A self-service returns portal suggests size swaps and alternate gear at the moment of return, so the revenue stays inside your brand.
  • Branded self-service returns portal
  • Smart size-swap and store-credit prompts
  • Return tracking so shoppers stop chasing status

Use case

A runner returns shoes that run narrow. The portal offers the wide fit instantly, and the return becomes an exchange, not a refund.

Business impact

Up to 54% of returns kept as exchanges, keeping revenue inside the brand.
Frame 2147228189

Get gear there before the game, not after

Sports ships against deadlines across UPS, USPS, FedEx, and regional carriers, and a late order is a lost one. ClickPost tracks every parcel in one place and flags delayed and stuck shipments early.
  • Unified tracking across US carriers
  • Early alerts on delayed and stuck shipments
  • Accurate delivery dates that hold up at peak

Use case

Ahead of a marathon, a brand catches delayed shipments in the control tower and expedites them before race day.

Business impact

Exceptions resolved before customers notice, fewer refunds and higher NPS.
Frame 2147228190

Feed fit and return data back into product and buying

See why gear comes back by style, size, and reason, then act on it. Return data becomes a fit signal for your product pages and buying.
  • Return reason and exchange reporting
  • Carrier and delivery performance visibility
  • Signals your merchandising team can use

Use case

Analytics show a shoe runs small and returns spike for size. The team updates the size guide and returns fall.

Business impact

Higher customer NPS and actionable data for product and buying decisions.
Frame 2147228191
BEYOND TRACKING AND RETURNS

Keep more of every order, and grow it.

Sports shoppers chase the right fit, buy against deadlines, and keep opening the order page. ClickPost adds three revenue moves built for exactly that behavior.

BEFORE IT SHIPS · ORDER EDITING

Let shoppers fix the size before the box leaves

Customers edit size, variant, quantity, and address themselves from the order page, inside a window you set, so a wrong size gets fixed instead of turning into a return.
  • Self-serve size, variant, and address edits
  • Address validation pre-dispatch
  • Merchant-set edit window with 3PL sync
30% fewer order-change tickets
PROTECT REVENUE · RETURNS PROTECTION

Stop wardrobing and serial returns from eating margin

ClickPost segments high-risk shoppers and applies eligibility rules by customer, region, or SKU, so a generous policy rewards real athletes without funding abuse.
  • AI segments serial returners
  • Eligibility enforcement by customer or SKU
  • Package protection for lost or damaged orders
30% of returns revenue protected
GROW AOV · POST-PURCHASE UPSELL

Sell the rest of the kit while attention is high

ClickPost surfaces AI-picked gear and accessories on tracking and order pages and inside the returns flow, so a size swap becomes a bigger basket.
  • AI recommendations on tracking pages
  • Complementary gear during returns flow
  • Upsell revenue that lifts AOV
+AOV from post-purchase recommendations
