Jeeng (formerly PowerInbox, acquired by OpenWeb in 2022 and now marketed as OpenWeb Email Monetization) is a multichannel monetization and audience-engagement platform for digital publishers. It helps publishers grow first-party, opt-in audiences and generate advertising revenue across email newsletters, websites, push notifications, and newsreader apps, reaching more than 150M opt-in subscribers. Its products — AdFill, AdServe, AdMarket, and Renderer — fill vacant ad inventory with monetized content, extend direct ad campaigns into email through existing ad servers, connect advertisers to opt-in audiences, and streamline Google Ad Manager ad-ops workflows. Publisher integration is handled through merge tags, per-newsletter ad tags, and cs_email tracking parameters plus direct Google Ad Manager integration; campaigns and reporting are managed through the portal at manage.jeeng.com. Jeeng also publishes partner Reporting & Management APIs at developers.jeeng.com — an advertiser API for campaign line and creative management plus campaign/performance reporting, and a publisher API for container, placement and publisher performance reporting — served from powerinbox.azure-api.net behind Microsoft Entra ID OAuth 2.0 client-credentials tokens. API access is not self-serve: an account manager provisions the client id and client secret.
