In Klaviyo, a flow is an automated sequence that is set in motion by a specific trigger and then includes one or more steps. Flows make it easy to initiate and nurture relationships with your subscribers and customers over the course of their lifecycle. You can automate messages that will help grow your business, without losing any of the personalization and relevancy needed to build strong customer loyalty.
With flows, you can trigger a message, or series of messages, based on when someone joins a list, is added to a segment, or takes any other action — such as making a purchase or abandoning a cart. Any data syncing to your Klaviyo account can be used to trigger and target automated flows. Flows help you send timely communications to recipients via email or SMS and can simply apply certain actions, like updating a specific field on a profile.
In this article, you'll learn more about flows and how triggered messages can fit into your email marketing strategy.
Which Flows to Set Live First
Four of the most popular flows are also the ones you should set live first. In order, they are:
- A welcome series flow to introduce subscribers to your brand and convert them into first-time customers
- An abandoned cart flow to convert would-be customers; this flow is customizable based on items in someone's cart and whether they're already a customer
- A post-purchase flow to show appreciation for customers and let them know about related products they might be interested in
- A winback flow for customers who purchase but then don't come back to buy again, customizable based on the products they've purchased and how many purchases they've made
Types of Flow Triggers
Every flow must have a trigger. A flow's trigger is what sets the automated series in motion. There are four types of flows:
People will qualify to enter a list-triggered flow when they are added to a specific list. One example is the welcome series.
People will qualify to enter a segment-triggered flow when they are added to a specific dynamic segment.
People will qualify to enter a metric-triggered flow when they take a specific action (for example, placing an order). To see all possible metrics that can trigger a flow, check out your account's Metrics within the Analytics tab.
- Date Property-Triggered
People will qualify to enter a date property-triggered flow if they have a specific date-based profile property set (for example, a birthday).
Klaviyo's Built-In Flows
When you integrate an ecommerce or nonprofit platform with Klaviyo, we will provide different best practice flows for you out-of-the-box.
After configuring your core company details in the Setup Wizard, you can navigate to the Flows tab in your account. Here, you will see any best practice flows we have pre-populated. These flows will contain default templates that provide a suggested layout and example text. Most of these templates will also be configured to pull in relevant dynamic personalized content through your integration.
When you find a flow that you would like to add to your account, click on it to see the preview modal. Here, you'll see:
- A live preview of what the flow looks like
- A short description of the flow's goal
- How the flow is tagged
- The flow's name (editable)
- The tag that will be added to the flow (editable)
- The flow's trigger (editable in some cases)
- Any necessary prerequisites for using the flow
Once you click Create Flow, you will be brought to the visual flow builder where you can edit and customize the flow to suit your needs.
Even if you don't integrate any third-party tools, you will still get a standard welcome series flow. This flow is triggered when new subscribers are added to a list. When editing this flow, you will need to select the list you would like subscribers to be added to in order to trigger the welcome series.
Create a New Flow
To create a new flow, click the Flows tab in your account's main navigation sidebar and then click the Create Flow button. If you aren't sure where to start, browse the Flow Library for innovative automation ideas spanning the customer lifecycle. Otherwise, click Create from Scratch to create a brand new flow.
When creating a brand new flow, you'll first need to name your flow. The name of your flow should be easily understood by you and your team — as you start to use Klaviyo more and more, the number of flows can add up quickly.
Next, you'll select a trigger for your new flow — you will be able to choose one of four options outlined above: list, segment, metric, or date property.
You will narrow each trigger. For example, if you choose a list-triggered flow, you'll need to choose which specific list will set your flow in motion.
Set Up Your Trigger Filters and Flow Filters
Whenever someone qualifies to enter a flow based on the trigger, we will also first check all trigger and flow filters:
- Those who fail the trigger and flow filters at this time will be filtered out immediately and will not be scheduled for any components in your series.
- Everyone who passes the flow's trigger and flow filters will officially enter the flow and be scheduled for messages and splits based on the delay period you've set.
- Before each step (email, SMS, split, etc.), flow filters will be checked once more to ensure that recipients still meet the criteria of the flow. Trigger filters are not checked again at send time.
When each message is scheduled to send, Klaviyo will apply your flow filters again (e.g., has Placed Order zero times since starting this flow) and skip anyone who fails these filters at send time. This is why you may see people queued up for flow messages — in the Waiting bucket — who you know shouldn't actually get the message based on the flow's filters. If someone qualifies to get the message initially upon entering the flow, this person will appear as waiting for messages in your series. Flow filters will always be applied again, however, right before each message sends.
You can explore the complete Recipient Activity for a given flow message by clicking on View all Activity in a message's left-hand sidebar. Here, you will also see who was skipped from receiving a message in the Skipped tab. When you click this dropdown, this will reveal a range of different skipped options. When someone no longer qualifies to receive a flow message at send time, we'll skip over them—most often, someone will be skipped because they fail the flow's filters, or because they've since unsubscribed and are suppressed in your account.
Back-Populating Flow Recipients
If you create a new flow and want to queue up those who would have been captured by the flow if it had been running previously, you can use our back-populate feature. This feature can be found in the Manage Flow dropdown menu.
Learn more about back-populating a flow.
Add Steps to a Flow
After you create a new flow, select a trigger, and add any desired trigger and/or flow filters, you are ready to start adding additional components into your flow series.
To add an email into your flow, click on the email component in the sidebar and drag it onto the visual canvas. Every "droppable" location for an email will turn green as you drag it onto the canvas, and a light green drop zone will appear as you get close to a drop point. Once an email is dropped onto the canvas, it can be configured in the lefthand sidebar. Learn more about the Email component.
To add an SMS message to a flow, drag the SMS component onto the visual canvas. Learn more about adding an SMS message to a flow.
Schedule a Step in a Flow
Messages and other components are scheduled by time delays that are added before them in a flow series. If components are back-to-back, without any time delays, they will all occur simultaneously.
Each time delay creates a waiting period between one component and the next. In this way, emails in a flow series will be scheduled relative to one another. This means that if Email #1 in a flow is sent one day after the trigger event, and you drag in a time delay set to two days between the first email and the second, Email #2 will be sent three days after the trigger event.
You can set a delay to any number of minutes, hours, or days. To send a message immediately after the previous step, you don't need to drag in a time delay at all.
You can also choose if you like to set a delay until a specific time of day or delay until only specific days of the week.
After you set a delay, you can always adjust it by clicking on the time delay component. Keep in mind that updating a time delay before a message will not impact any already-scheduled messages. The updated timing will only impact newly scheduled messages moving forward.
The Flow Action Status
There are three possible statuses for a flow action: draft, manual, or live. You can change the status of a message in the left-hand panel or by bulk updating the status for every action.
This is the default status for a new message and is the status you should use while you're still configuring your content and adjusting settings. When a message is in draft, nobody will be queued up or receive it. If you change a message in a live flow to draft, contacts will move on to the following step and skip the draft message.
When you are done configuring a new message and are interested in testing it out, you can place it in manual mode. When a message is in manual, it is active in your flow but no manual messages will send automatically. You will need to manually review and send all scheduled messages. When a contact is scheduled as "needs review," they will then move to the next step. If you have live messages later in the sequence, they can still receive these while waiting for approval to receive manual messages.
To "turn on" a message in a flow series, you will want to change the message's status to live. A live message is active in your flow and is sending automatically.
When a flow message is set to manual, you will see all ready-to-review-and-send messages in the Needs Review section within the Analytics snapshot in the left-hand sidebar. By clicking View all Analytics, you will be taken to a report where you can explore all recipient activity for your flow message.
If you switch the status of a message from manual to live, any messages in the Needs Review section will continue to remain there until manually reviewed and handled—these messages will not automatically send when the message's status switches to live.
From the Needs Review section within Recipient Activity, you can choose to Send All or Cancel All, or alternatively click Send Now or Cancel for an individual message.
If your flow message has a time delay before it, you will also notice individuals queued up in the Waiting section within your message's Recipient Activity. This view shows you who entered your flow and is currently waiting to receive the selected message.
In order to understand how a flow is performing overall, you will want to view message performance across your whole series. With the Visual Flow Builder, you can show analytics on the visual canvas itself. To do this, once inside the builder for a given flow, click Show Analytics on the top header menu. Then, you'll see all message cards expand to feature a key performance metrics with an adjustable timeframe.
For each action, when selected, you can also view a 30-day snapshot in the sidebar and click in to view robust analytics around that action step in your series.
