Do review request emails indirectly boost future conversion?

I'm running an e-commerce store and want to understand the potential impact of post-purchase review request emails on future customer conversions. While I understand these emails are typically used to gather feedback, I'm curious whether they might have a secondary effect of subtly influencing customers' likelihood of making repeat purchases. Are these emails just a feedback mechanism, or could they serve as a strategic tool for improving long-term customer retention and conversion rates?

TL;DR - Quick Answer

Size guides reduce returns by 15-30% and increase conversion by 8-15% for apparel and footwear. Shoppers who can't confidently determine their size either buy and return (costly) or abandon (also costly). A clear size guide eliminates both outcomes.

Can a Size Guide Reduce Friction and Increase Conversion?

Size uncertainty is one of the leading causes of cart abandonment in apparel and footwear. Shoppers who aren't confident about sizing face a costly dilemma: buy and risk a return (which erodes trust and margin) or don't buy at all. A well-designed size guide resolves this uncertainty before checkout, removing one of the biggest friction points in the purchase decision.

Size Guide Impact by Category

Category Conversion Lift Return Rate Reduction
Footwear+12-20%-20-35%
Fitted clothing (tops, bottoms)+10-18%-15-28%
Swimwear / lingerie+15-25%-25-40%
Kids' clothing+20-30%-30-45%
Loose/oversized styles+5-10%-10-18%

Size Guide Best Practices

  • -Placement: Link directly from the size selector - "What's my size?" next to the size dropdown
  • -Format: Include both measurements AND model dimensions ("Model is 5'8" wearing size M")
  • -Brand comparisons: "If you wear Nike size 9, order our size 9" reduces uncertainty dramatically
  • -Fit notes: "This runs small - order one size up if between sizes" is worth more than a chart
  • -Mobile-first: Size guides in modals load faster than separate pages on mobile
