I have used growthpush on two different platforms, as well as multiple times in my own business. The team is very responsive to any questions or concerns we may have. They are great about providing detailed analytics reports that give you actionable insights into your performance issues. In some cases it has been difficult to determine an issue's root cause when using other providers (e.g., Google Analytics). We had no problems with this provider, but there were many others who did! Do not hesitate - if they can help you and their service looks like what you need, take advantage of them. Using Push Notifications for email marketing campaigns, our goal was to increase click-throughs from optin pages. Our objective was met by nearly doubling conversions from these types of emails compared to normal emails sent through GCP. I like how easy it is to set up, configure and manage all my apps using this platform - Pushbullet, Facebook Messenger etc. The price point is great as well! Nothing at all really. It's been good so far but nothing major has come out of it yet. We are solving distribution problems in our organization by providing better customer engagement through messaging platforms.
