Hello @Martin_Dee,
Great question!
At present it would not be possible to create a segment that filters off of just a partial phrase or property. Klaviyo’s segment and filter definitions require exact match phrasing to evaluated. @alex.hong has a great write up and explanation of this in his Community post which I’ve included below:
I think it’s also helpful to further understand different data types and how it effects your segment and flow filters. I recommend taking a look at the About Data Types Help center article Klaviyo offers to learn more.
In addition, both @Dov and @Hussein Kdouh touched upon this subject in a recent Community post which I’ve included below:
Thanks for being a Klaviyo Community member!
