Hi there,

I’m trying to migrate from another provider, and I ran into a general question for the segmentations. I have a lot of companies and each of them should receive different campaigns. What I thought about, but don’t want to do is to create a Segment checking the Organisation Name / Custom Field for each created organisation, because then I will have thousands of segments. I didn’t find dynamic segmentation with parameters.

My software triggers an Event that should be send to all people of an organisation, but only them so I have to use a segmentation.

What’s the “approved” way of doing things like that? I need it to work over API and I need it to be performant.

Maybe anyone has an idea that I can research on further

Thanks in advance and Cheers
