This guide distills the video “Whatnot tips, things I wish I knew before starting Whatnot” into an actionable playbook for new and growing sellers. Whatnot isn’t a typical resale site—it behaves like “60% live commerce marketplace + 40% social network.” Success comes from consistency, smart sourcing, compelling live shows, and community leverage. Use giveaways to cold-start growth (follow-gated entries), schedule recurring shows to build repeat buyers, and maintain deep inventory so your auctions never stall. Set up a shipping workstation with thermal labels, bubble mailers, boxes, and poly mailers to ship fast and keep 5-star reviews. Join the Whatnot community and organize/participate in raid trains to share audiences. Optimize thumbnails (face + bold text + clean bright backdrop) and treat shows like a performance: disclose flaws honestly, double-pack, and ship within 24–48 hours. A weekly operating rhythm—weekdays for listing/setup, weekends for shipping—turns chaos into scale.
