I recently started using EngageSpot and I'm absolutely loving it! The features are incredibly powerful, yet easy to use. I'm able to easily create automated messages . I'm also able to create personalized messages and track my result on engagespot dashboard. EngageSpot is helping me to grow my product in a very efficient and effective way. Highly recommend it!
I like how it is a lightweight, highly extendable solution that is easy to use and which gives you control over your notifications without making you struggle with low level code. It is well-documented too, so it's easy to get started and quickly add new features afterwards.
I like how it is a plug and play solution for setting up a notification engine for any applications which supports a wide variety of channels, which otherwise be tedious to build from scratch. Recommending to anyone who wants to set up notification system in their application.
For a product aiming for web applications, not having a proper integration with React (and all other SPA frameworks, really) is a terrible business choice. It is a poor solution for a very simple problem.
