We have built a workflow with an incremental query to target X people during an X period of time with a recurring delivery. The way it works is:
- Data workflow with an incremental query and an end button that start the marketing workflow.
- External signal on marketing workflow that picks up the data from the data workflows and sends the email out as a recurrent delivery.
Everything was running smoothly and working fine seems September but the emails have suddenly stop sending and it only sends if we manually re-build the workflow. Within the journal of the workflow it shows that the delivery is ready to prepare but all the approvals are taken out of the delivery and the prepare delivery is not showing up in any delivery folder.
Would you have any idea of why this is happening by any chance? Is there a certain amount of deliveries that you can only send with a recurrent delivery?
Thanks for getting back. No, we haven't upgraded our instance neither done any significant change/ maintenance operation (I have just checked with the technology team).
The only thing I added on the delivery where some addresses and HTML pixels. We thought that might have been the reason of failing so I removed them. The email was sent when I manually re-start the workflow but it got stuck again on Prepare again next day. I have removed the old delivery and created a new one from the scratch and it seems to have worked now. I just thought you could maybe help understanding the reason why this has happened.
