How XFlow works
XFlow’s back-in-stock system is built around three core components:
Campaign → Workflow → Email template
They work together to create a complete automation flow.
Think of it like this:
Campaign = What you’re running
Workflow = What happens when restock occurs
Email template = What customers receive
Together, they form one seamless automation.
Campaign management
A Campaign defines:
Which products are included
When it is active
How it is prioritized
How performance is tracked
Each campaign runs independently, meaning you can activate, pause, or modify one without affecting others.
⭐ Example:
A “Winter Collection Restock” campaign
A “VIP Early Access Restock” campaign
Both can run at the same time, but each has its own rules and tracking.
Key elements
Scope
Defines which products or collections the campaign applies to
Schedule
Determines when the campaign becomes active and inactive
Priority
Resolves conflicts when multiple campaigns target the same product
Status
Controls whether the campaign is active or inactive
Workflow
Defines the automation logic associated with the campaign

CampaignsWorkflow builder
A Workflow defines what happens when a product in a campaign is restocked.
When inventory updates:
XFlow automatically triggers the workflow
The workflow runs predefined actions (like sending emails)
Instead of manually notifying customers, everything runs automatically.
⭐ Example:
When product restocks →
Send back-in-stock email
Wait 24 hours
Send a reminder
Workflows can be reused across multiple campaigns.
Key elements
Trigger
Defines when the workflow starts, such as when a product is restocked.
Conditions
Optional rules that determine whether the workflow should continue.
Actions
Define what the workflow does as an outcome.
Workflow flow
The sequence that connects triggers, conditions, and actions into a complete automation journey.

WorkflowsEmail template builder
The Email template builder is where you design the actual email customers receive.
You can:
Create branded restock emails
Add dynamic product details
Personalize with customer data
Reuse the same template across campaigns
Templates are connected to workflows — when a workflow says “Send email,” it uses your selected template.
Key elements
Visual email editor
Build email layouts without writing code.
Dynamic content variables
Personalize emails by inserting dynamic product and customer data that automatically updates at send time.
Reusable templates
Create, save, and reuse email templates across multiple campaigns and workflows.
Preview & testing
Preview emails before sending to verify layout, content, and personalization.
