The signup form that you set up is triggered by Welcome Flow. When someone fill-up the form they go through by Welcome Series. Make sure that triggered!

And the Abandoned Cart Flow is triggered by When someone “Checkout Started” and Flow filter is “Placed Order” zero times since starting the flows. 

Hope you will be able to make it!

If it’s still not working check the Activity Feed, still not working maybe your integration problem.

hi, 

thanks for your reply. All the settings appear correct to me, but still subscribers don’t get into the welcome flow, specially when they go into another segment (engaged etc etc). I have noticed the problem with customers who subscribe, then for example add something in their cart and they become automatically engaged, and the welcome flow is not triggered.

that happened yesterday  as well with a new subscriber.

@Daniele_Caglio  can you tell us more about your welcome flow? How do you trigger it? NEwsletter list, a specific segment or something else?

Welcome flow is triggered when someone is added to newsletter...that’s it

@Daniele_Caglio  I do understand but is it a list or segment?

when someone goes into the newsletter list the flow it is triggered, but I am noticing that if a new subscriber gets immediately in the engaged segment because maybe he has seen some products he doesn’t get into the newsletter list so the flow is not triggered...

Hey @Daniele_Caglio, 

Is double opt-in enabled on your Newsletter list that triggers your Welcome Series flow by any chance?

If double opt-in is enabled on your list and the customer has signed up to your Newsletter list but has not confirmed their subscription, the contact would have a profile created within your Klaviyo account and may get captured by segments but would not be added to the list and thus not triggering and being served the Welcome Series flow. With double opt-in enabled, only contacts who have confirmed their subscription would be added to the Newsletter list and then trigger the Welcome Series flow. 

I would also recommend taking a look at a similar post from @ezerosi regarding a similar topic which other members have suggested some helpful troubleshooting tips:
