ELMA promotes the effectiveness of doordrops, which includes the distribution of print media such as leaflets, flyers, catalogues, brochures, free newspapers, and product samples.

Its vision is to be Europe’s “centre of excellence and innovation for letterbox marketing”, and provide clients with superior resources, experience, and knowledge, all in a sustainable format.

The business selects its members carefully to represent the best in class in each market, ensuring quality and professionalism for clients looking to use this channel.

“Doordrop, or unaddressed mail, is a highly effective and popular media to promote products and services as it directly engages the consumer in the relaxed environment of their homes,” said ELMA chairman Mark Davies.

“They are accountable and integrate wonderfully with other in-home media, such as television and the internet.”

He added: “We are delighted to become a member of Two Sides. As a letterbox marketing association, it is important to highlight the sustainability of our products.

“By joining Two Sides, we have access to a range of resources and facts that are great to help us communicate sustainability within our own business and to our customers.”

As a Two Sides member, ELMA has access to a large library of co-brandable communications tools, consumer research, sustainability advice, and events.

Jonathan Tame, managing director of Two Sides UK, said: “Our partnership with ELMA will help us tell the great sustainable story of doordrop mail, to consumers, to inform them about the environmental merits of print and paper.

“Welcoming new members on board is always a pleasure and we look forward to working with ELMA.”

Print procurement platform Webmart and hybrid mail specialist CFH Docmail have also recently joined Two Sides as members.
