Retargeting campaigns have reduced booking cancellations but new users still need clearer guidance
I believe that retargeting is the best feature that Insider offers. The ease of use and the results are why the retargeting feature stands out for me. Insider reads the results near real-time and provides AI segmentation. We only need to prompt, and then Insider will work to determine which segment is best for each campaign. Insider has helped me to reduce cancellation bookings by about 15% year-over-year. This is tracked through Insider; however, we also add additional attribution using AppsFlyer. We see significantly fewer employees needed for outbound calls because with Insider, we perform a reconfirmation of booking schedules automatically. This allows us to reduce the need for customer service outbound agents, and Insider has also helped us reduce cancellations.

Regarding the transformations I mentioned, everything worked as expected. However, figuring out how it worked took a long time. The issue is that RudderStack's documentation does not explain the transformation flow well, making it hard to understand where the transformation was applied because of different sources. For example, Node.js had one format, and the frontend part with JavaScript had another format, and I did not know how to work with transformations between these nodes due to lacking documentation. I had to conduct many tests over months to gradually figure out how the transformation worked. I experienced another problem with name restrictions that were not documented. I remember using "name" in a transformation to transform from a generic name such as full_name to "name", but sending it to CleverTap did not work without providing any error. It merely did not arrive. It was not until I switched the variable name from "name" to "short_name" that it worked. It took two days to realize this issue was not in my transformation or the JSON I built but rather a name limitation not mentioned in the documentation. Essentially, the main problem is the documentation, which I find terrible. When it does exist, it is not very helpful. One problem I have seen in RudderStack's documentation is that because it covers many tools and different destinations, there is a lot that is poorly documented and does not explain how it works, which I believe is due to many different destinations and edge cases that are not mapped in the documentation. For example, in Meta Ads, there are usage permissions issues when you create a Meta app to use the API, leading to various permission conflicts regarding number verification that require an API call via Postman, among other potential problems. RudderStack can improve mainly in its documentation, which is lacking. It does not adequately explain how to use the platform, what edge cases exist, and issues such as forbidden names are not explained either. The documentation around Transformations needs to be better as well, to clarify RudderStack's data flow and how it treats incoming data from sources such as JavaScript, which would assist in understanding the expected JSON for each type of information. A potential problem beyond documentation relates to a limitation on API calls for external enrichment. Specifically, I have had a two-second lifetime limitation for the transformation to make an API call, wait for the response, and insert it into the flow. Two seconds can be a very short time.

Pros

"Insider has helped me to reduce cancellation bookings by about 15% year-over-year."
"Insider is simple to use, making it easy to learn and navigate the platform, so the learning curve is fast."
"Working with RudderStack has positively impacted my organization by increasing productivity and effectiveness among cross-functional teams, especially since I can connect to third-party destinations without making changes in my apps or submitting new builds to app stores."
"The best feature RudderStack offers is a clean UI, with an overview of how everything is routed and how easily I can disconnect and connect different sources."
"RudderStack has impacted my organization by allowing us to integrate our customers and providing scalable visibility into the activities within our system."
"With RudderStack, all of that becomes much easier."
"RudderStack has positively impacted our organization by helping us keep our customers happy because we are able to track the data, and according to that, we are improving the product and the experience of the customer."
"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."
"RudderStack has positively impacted my organization by helping us unify our user profiles across different channels without a lot of worry, such as connecting users visiting our landing page and our Shopify store, which really helped us drive better analytics and improve our targeting and marketing."
"The best features that RudderStack offers, in my opinion, include its main feature, which is having a fast connection with destinations where you will use the platform, so you do not waste time with configurations and name transformations."
 

Cons

"I did not enjoy using Insider AI to generate copies, push copies, and messages."
"I think that Insider can be improved on the UI side because for someone with experience, Insider would be a very great tool."
"RudderStack should work on its sync time; currently, the minimum sync time for injecting data into warehouses is about 30 minutes."
"The customer support is pretty much nonexistent."
"The customer support is adequate; there could be regional issues, and while the US team is reliable, I'm based in the Middle East, which has a big time difference that hasn't always helped."
"The dashboards could be improved; as far as I knew at that time, you could host your open-source self-hosted dashboard, but it was not at the level of the online version, which was free to use."
"RudderStack can improve mainly in its documentation, which is lacking. It does not adequately explain how to use the platform, what edge cases exist, and issues such as forbidden names are not explained either."
"The biggest friction point or frustration I have encountered with RudderStack is documentation and updates to the releases."
"RudderStack could improve by adding environment concepts for organizing development, staging, and production setups, as the current structure often confuses me, highlighting the need for clearer visibility of historical data for debugging and troubleshooting."
