Thanks for the update, Benjamin! A couple more things to double-check: - Are there any filters, splitters, iterators, or routers in your scenario after the aggregator(s)? - In your aggregator settings, is it set to “aggregate all bundles from the previous module” (not using any grouping key)? - Try removing the array aggregator and just keep the text aggregator directly before your Email module (sometimes using both can cause a split). - If you run the scenario with logging on, do you see more than one bundle output from the aggregator? If all else fails, could you post a screenshot of your scenario’s flow (modules and connections), including the aggregator settings? It might help spot anything subtle. Happy to troubleshoot deeper if you can share that view! Tim
