Remote Volunteering

About the Non-Profit Organisation

Letzte Werbung e.V.

Letzte Werbung is a non-profit and independent association that works voluntarily to ensure that mailbox advertising is only permitted with the consent of the recipient. In this way we eliminate one of the biggest wastes of paper, plastic, CO2 and water and save millions of trees every year.

Hundreds of thousands of citizens from all over Germany and numerous environmental and consumer organisations such as BUND, NABU or Greenpeace have already supported us. With extremely successful campaigns such as the collection of more than 70,000 objections on, the distribution of more than 100,000 No Advertising Stickers and the big Bundestag petition "Briefkastenwerbung nur auf Wunsch" (mailbox advertising only on request) with 18,000 signatures, we have brought the issue into the public eye.

Now it is time to change the law and follow the will of more than 60 million people in Germany.

More about the organisation

About the volunteering opportunity

Program an app that abolishes mailbox advertising

It breaks our hearts when millions of trees are felled, treated with chemical processes and printed with toxic ink, only to be thrown into the trash unnoticed.

For this we would like to make our contribution and send to each humans in Germany a no advertisement sticker. You can participate! 

Our detector app allows you to have an advertising-free mailbox without stickers. And if something does come in, you can take legal action against it. 

This way you can help

Community and value-oriented

We are the good guys, the do-gooders of the world - and together we define the moral pillars that define us.
