My verdict: the most well-known, but has become frustrating for Growth profiles.
It's the most well-known, but they've pivoted heavily toward Sales, which is frustrating for a Growth profile. You quickly feel limited and it doesn't really allow for scaling.
It's great for visual personalization and sales teams, but for a pure Growth Engineer who wants volume and flexibility, it has become less relevant.
What I like less: the Sales positioning that limits Growth use cases, the high pricing for volume, and the difficulty scaling.
My advice: for Sales teams and visual personalization, it's good. For Growth volume, Emelia or Instantly are better.
