About Greendimes
Greendimes operates as a service-focused enterprise dedicated to reducing unsolicited physical mail for households in the United States. The company was established on August 18, 2006, with Pankaj Shah listed as a principal contact. Over its history, the company has also been known as Tonic Mailstopper, with actor Matt Damon serving as a board member for the initiative.
The core of Greendimes' business is to act on behalf of its subscribers to remove their names from direct marketing and mailing lists. This service aims to eliminate a significant portion of unwanted mail, including credit card offers, insurance promotions, sweepstakes entries, and catalogs. The company claims its efforts can reduce a household's junk mail volume by as much as 90%. Revenue is generated through a subscription-based model where customers pay a fee for the service. For instance, a $20 fee was previously cited for the full-service option.
Greendimes provides different tiers of service. A free, do-it-yourself option allows users to manage catalog removals, while the paid premium services offer more comprehensive and continuous monitoring. As a component of its business model, a portion of the subscription fees is directed toward environmental initiatives. Specifically, the company commits to planting trees on behalf of its subscribers, linking its commercial service directly to a positive environmental impact. This dual focus on consumer convenience and ecological contribution forms the central value proposition of the company.
