# What are campaigns
**Campaigns** are the control layer that decides **who gets notified, when, and with which workflow** when a product is back in stock.
Think of a campaign as the *manager* that connects your products, workflows, and emails into one targeted restock strategy.
***
## Definition
A campaign defines:
* **Which products or collections** are included
* **Which workflow** runs when they’re restocked
* Whether the campaign is **active or paused**
You can run multiple campaigns at the same time, each with its own logic.
## How campaigns work
{% hint style="info" %}
1. A customer subscribes via the ["Notify me" widget](/xflow-app/notify-me-widget/customize-notify-me-form-and-messages.md).
2. The product or variant is restocked
3. XFlow checks which **campaign** the product belongs to
4. The campaign triggers its assigned **workflow**
5. Emails are sent based on your workflow rules (timing, conditions, follow-ups).
{% endhint %}
> In short: **Campaign = scope + control**, **Workflow = logic + actions**
## Benefits of using campaigns
:white\_check\_mark: **Targeted messaging**: Run different restock strategies for bestsellers, seasonal items, or limited drops.
:white\_check\_mark: **Better control:** Pause, edit, or replace workflows without touching your widget or emails.
:white\_check\_mark: **Scales with your store:** Start with one global campaign, then add product- or collection-specific campaigns as you grow.
:white\_check\_mark: **Cleaner reporting:** Track performance by campaign instead of mixing all restock alerts together.
## Best practices
* Start with **one global campaign.** *Learn more:* [Global restock campaign](/xflow-app/getting-started/quick-start-guide/global-restock-campaign.md)
* Create separate campaigns only when products need **different workflows.** *Learn more:* [Advanced restock campaign](/xflow-app/getting-started/quick-start-guide/advanced-restock-campaign.md)
* Avoid overlapping scopes unless you intentionally manage priority.
