thredUP Affiliate Program

The simplest and fastest way to join the thredUP affiliate program is to sign up to 37X and generate your own affiliate marketplace within a few minutes. We are pre-approved to run marketplaces through our partner affiliate networks and merchant programs. 37X transparently reports all marketplaces it operates to both affiliate networks and merchants.

Sign up for 37X and create your first site. Once your site is created, click to manage the site and then navigate to tools > affiliate link generator. Once you are there, copy and paste your desired destination url into the tool and click generate. The 37X system will generate the best possible link for that url that you can share. Alternatively, when you generate a site, the catalog will automatically include affiliate links for products. You can view the product catalog for your site in the product management section and copy links directly from there. We highly recommend that you publish and connect the site to your own custom domain before generating links. You can publish your site to a custom domain via the settings > domains DNS configuration.

Earnings on the thredUP affiliate program vary based on traffic quality, product category, and region. With 37x, you can earn up to 4.0% commission. Your actual results depend on your niche, audience, marketing strategy and supplier specific program terms.

Payout terms vary by merchant and affiliate network. 37x partners with all major affiliate networks and always routes traffic through the link with the best revenue potential. Once the network confirms payment to 37x, we pay you within 30 days. Most networks pay between 14 to 90 days after conversion, so with 37x's payout window added, expect payouts between 44–120 days in total. Some partners also require minimum thresholds before payouts are released.

With 37x, you can earn up to 4.0% commission on thredUP products. We often negotiate higher rates on behalf of our marketplace creators, as we collectively drive significant value to our affiliate merchant partners.
