I use ActiveCampaign integration for my own business and all my client's businesses. A very robust system, with high-quality integration and new features added all the time.
We've been using both ActiveCampaign and Shopify for multiple years now. We love that we now have been able to connect the two to see how our customers are behaving across the two platforms. This was definitely a game changer!
I use ActiveCampaign (separate software) for my email campaigns. This shopify app is needed to integrate that software with Shopify. I'm not exactly sure what the Shopify app does, just that it is needed. All is working fine.

We use the automation technology in Active Campaign to send out Welcome Emails and also a series of Abandon Cart emails, which has grown immensely. We love it! And having a technician there for you whenever you need help has been lifesaving!
