Personizely: A/B Testing & CRO

The app is exceptional. The creative freedom is crazy good, the analytics are amazing and, whilst the support team asked me not to mention this, but just review the app, I need to tell you, these guys are the best you'll ever experience in terms of support from an app on Shopify. Hands down. I say that as someone who's been on Shopify for 10 years. No one matches so far in my experience what these guys are willing to do to help.
