What we build

Everything for the newsletter
craft.

Six building blocks that together deliver exactly what usually takes three tools and a technician.

01
Baustein

Editor like a blank page.

A visual editor that feels like writing in Word — except a responsive email comes out at the end. Templates, blocks, custom fonts, real previews.

  • Drag-and-drop blocks
  • Custom templates
  • Live preview for mobile & desktop
  • AMP-ready blocks
02

  • Timezone scheduling
  • Series & automations
  • Send-time optimisation
  • A/B tests
