Mastering Shopify Flow's "Wait" Action: Stop Unexpected Emails and Ghost Triggers
Hey everyone! As a Shopify expert who spends a lot of time digging through community discussions, I often come across those head-scratching moments that make us all feel a little less alone in the world of e-commerce. Recently, a thread titled "Wait Action Issues" caught my eye, and it perfectly illustrates a common, yet often misunderstood, quirk within Shopify Flow.
It’s the kind of problem that makes you question your sanity: you’ve built out a beautiful, logical flow, but then a "Wait" action fires when it absolutely shouldn't, sending an email or triggering an action that goes against all your conditions. Let's dive into what happened and, more importantly, how the community rallied to find a solid workaround.
The Mystery of the Firing Wait Action
The original poster, @ukecom, was building out some essential flows – abandoned cart, thank you, welcome sequences – all within the native Shopify Flow app. Their abandoned cart flow had a pretty standard setup: a trigger, then a condition like, "Customer has not received another abandonment email in the last 14 days?" If the answer was False (meaning they had received one), the flow should ideally just stop there.
If True, it would move to another condition, checking if items were still in stock, and if so, proceed to a "Wait 15mins" action. Sounds logical, right? But here's where the frustration kicked in:
"the condition sees customer has received another abandonment email in the last 14 days, goes False which is a dead end. - the next conditon for stock levels of items in their cart (only connected to the true output of the prior condition), does not light up - but the 'Wait 15mins' node after that FIRES… and in turn, continues on the path after that wait node!"
Talk about confusing! A condition evaluates to False, a subsequent true-path node doesn't even "light up," yet a "Wait" action further down that supposedly dead path still fires. It feels like a ghost in the machine, and as @Maximus3 rightly pointed out, "A flow step being false and continuing down a true path is not something I’ve ever seen lol." It certainly goes against common automation logic.
Unpacking the Shopify Flow "Quirk"
Thankfully, @Mustafa_Ali stepped in with some brilliant insights, confirming that this isn't a mistake in logic but a "known quirk with Shopify Flow." The core issue? Shopify Flow runs are independent.
Imagine a customer abandons their cart, triggering a flow. Let's call this "Run A." Run A proceeds, hits your initial conditions, passes them as True, and schedules its "Wait 15mins" action. Now, before those 15 minutes are up, the same customer abandons another cart (or some other event triggers the flow again). This creates "Run B."
Run B starts, hits your initial condition, and this time, it correctly evaluates to False (because Run A has already 'claimed' the customer or sent an email recently). Run B stops. But here's the kicker: Run A's previously scheduled "Wait 15mins" action is still on the calendar! It doesn't care that a later run (Run B) decided the customer isn't eligible anymore. Once a Wait action is scheduled by an active flow run, it fires independently of subsequent flow runs for that same customer.
This means you can end up with duplicate emails or actions, even when your conditions *seem* robust.
The Community's Brilliant Fix: De-Duplication & Double-Checks
The solution, as shared by @Mustafa_Ali (and acknowledged as "great advice" by @ukecom), is to implement a robust de-duplication strategy. It's essentially about adding eligibility checks both before and after every Wait action.
Step-by-Step: Implementing the De-Duplication Strategy
Here's how you can fortify your Shopify Flows to prevent these ghost triggers:
-
Initial Eligibility Check: Right after your flow's trigger, you'll have your initial condition (e.g., "Customer has not received another abandonment email in the last 14 days?"). This is good, keep it.
-
Add a De-Duplication Condition After the Wait: This is the crucial step. Let's say your flow looks like this:
- Trigger (e.g., Abandoned Cart)
- Condition 1 (e.g., "Customer not emailed in 14 days?" - True path)
- Wait 15 mins
- Action (e.g., Send Abandoned Cart Email)
You need to insert the same or a similar eligibility check immediately after the "Wait 15 mins" action, but before your final action. So it would look more like this:
- Trigger (e.g., Abandoned Cart)
- Condition 1 (e.g., "Customer not emailed in 14 days?" - True path)
- Wait 15 mins
- NEW: Condition 2 (e.g., "Customer not emailed in 14 days?" - True path)
- Action (e.g., Send Abandoned Cart Email)
This ensures that even if an older, independent flow run's "Wait" action fires, the flow will re-evaluate the customer's eligibility *right before* sending the email or taking the final action. If the situation has changed (e.g., a newer flow run correctly stopped, or the customer completed their purchase), this second check will catch it, and the flow will dead-end, preventing the unwanted action.
-
Consider Using Tags or Custom Fields: For more complex scenarios, you can enhance de-duplication by setting a customer tag (e.g., "flow_running_abandoned_cart") at the very start of the flow's true path, and removing it at the very end. Your initial condition could then check for the absence of this tag. This provides a clear flag that a flow is actively processing for that customer, allowing you to stop subsequent runs immediately. Remember to clear the tag even if the flow ends on a false path, or if you use it for a limited time.
Why This Matters for Your Store
Implementing these de-duplication checks is crucial for several reasons:
- Customer Experience: No one likes being spammed. Preventing duplicate abandoned cart emails or welcome sequences ensures a smoother, more professional experience for your customers.
- Accuracy: Your automation should reflect your business logic. This fix ensures your flows behave as intended, maintaining data integrity and reliable customer communication.
- Resource Management: While native Shopify Flow is powerful, avoiding unnecessary actions and emails means you're using your resources efficiently, especially if you're tracking email sends or other metrics.
