Hi @jose r​ you need to share more info - such as screenshot of rules and when you say message was it an email or chat?

@user382​ these are the entry rules to the serie. When I say messages I mean email and push notifications. Thanks!

All are custom attributes, and I assume all the data, especially the date, is well set? How do you know only 41% received it? What's the message (email or chat - as chat can not be delivered if the user is not online)?

Exactly @user382​ , everything is fine including the dates. The messages are emails. In fact this series is a duplication of a structure that has worked for months. My question is why users do not enter the series, even though they comply with the entry rules?

Hmmm it might have something to do with the duplication. I would need to look at it in order to help you more. If you wish I can spare 30mins to go through this over a call, screenshare. Free of charge. But I can do it next week (starting Monday). I'm in CEST timezone.

@user382​ thank you very much for your time. The error was in the "exit" rules not in the "entry" rules, as I thought. Already solved. Thanks!

Great! Glad you sorted it out
