North German Fundraising Day on 14 April 2026
Donations are built on trust. And trust is created when communication feels personal, processes are reliable, and fundraising remains capable of acting quickly – even when urgency is high. This is exactly where we support you on site in Hamburg.

Our dialog marketing specialists Silke Zierfuß (silke.zierfuss@trebbau.com) and Katrin Elstner (katrin.elstner@trebbau.com) look forward to meeting you in person at our booth on site. Feel free to schedule an appointment in advance or stop by spontaneously – we look forward to engaging and inspiring conversations with you!
The “secret ingredient”: precise donor communication
