It enables me to create and manage an auto-responder series along with list growth management tools.
The goal is to continue to engage with my list. Keeping in touch with new and potential customers helps stay "on top of mind" when needing services.  Just like the name states, it has allowed me to stay in "constant contact" with my subscribers. The most valuable features are creating and…

Event tracking has transformed how we understand user journeys and improve product decisions
RudderStack provides a platform to ensure product quality and understand user behavior, allowing us to improvise and optimize our product. The tracking plan feature provides an optimized version of the events in a semantic way, which is very helpful. The default attributes such as page attributes, page properties, operating system properties, context traits, and user traits are also major aspects we use across events. Overall, RudderStack is a good tool. Additionally, I believe that organizations not using the high-price version of RudderStack should have access to the event audit API, which I consider one of the most fantastic features that every organization should have to track their events. A basic versioning of the event audit API or allowing stakeholders to upload event schemas via CSV to the tracking plan would be very helpful, but the tracking plan feature itself is fantastic. The best feature RudderStack offers is the analytics over the past two days, past seven days, past 30 days, or however much event volume has occurred in those windows. Other major features include the tracking plan feature, the code-generation feature, and the event audit API feature, all of which are very helpful across RudderStack. The best feature I rely on the most in my daily work is the volume of events in a specific time window, which I check every two hours during working hours. This feature gives me an idea of how my website is performing, the traffic flow during working hours, and alerts me if something breaks based on the event volume. RudderStack has positively impacted our organization by opening the door to tracking user journeys across the platform, understanding user performance and behavior, and assessing how well our product is doing. It helps us measure the impact of different features on our product. RudderStack has helped us reduce errors by revealing where users get stuck in their journeys, allowing us to improve our product and reduce manual efforts. If we understand user performance, we can optimize our product to reduce friction at key success points.
