## Example of workflow condition: An event occurred
**Trigger:** New customer sign up
**→ Action:** Send email (Send initial engagement email)
**→ Action:** Wait (Wait for email delivery and potential engagement)
**→ Condition:** **An event occurred - Email opened**
**→ Action (If False):** Send email (Send win-back email with special offer)
**Trigger:** New customer sign up
**→ Action:** Send email (Send promotional email with CTA links)
**→ Action:** Wait (Wait for email delivery and potential click)
**→ Condition: An event occurred -** **Email clicked** (Check if customer clicked email link)
**→ Action (If True):** Add customer tags (Tag customer as engaged)
⚠️ Without **CTA links in your email**, the “Email clicked” event cannot be detected.
**Trigger:** New customer sign up
**→ Action:** Send email (A marketing or promotional email is sent to the customer)
**→ Action:** Wait (The workflow pauses (e.g., for 7 days) to monitor the customer's interaction with the email)
**→ Condition:** **An event occurred - Customer unsubscribed**
**→ Action (If True):** Update subscription status - Cancelled (If the customer chose to opt-out, the system automatically updates their profile status to Cancelled to stop all future marketing)

**Trigger:** Product restock
**→ Action:** Send email (Send an initial "back in stock" notification to customers who requested an alert)
**→ Action:** Wait (The workflow pauses for 1 day to give the customer time to see the first email and complete a purchase)
**→ Condition:** **An event occurred - Customer purchased** (if the customer has made a purchase since the initial notification was sent)
**→ Action (If False):** Send email (if the customer has not purchased, send a follow-up "low stock warning" email to create urgency)
## Best practices
* **Add a Wait step:** Include a **Wait action** before adding a condition. This gives your customers a little breathing room to open the email and check out your message.
* **Include a clickable link:** If you want to track **Email clicked**, make sure your email includes a button or link. No link \= no clicks to track 😉
* **Create urgency with follow-ups:** Use the **False** path (for customers who haven’t purchased yet) to send a friendly reminder, such as a *“Limited stock available!”* message. This can help encourage last-minute conversions.
* **Keep your mailing list clean:** Use the **Unsubscribe** condition to automatically remove users who opt out. This helps maintain a healthy list and ensures you’re only communicating with engaged subscribers. *Learn more:* [How the unsubscribe link works?](https://docs.foxecom.com/xflow-app/email-templates/email-templates-faqs/how-the-unsubscribe-link-works)
