Can we create custom audiences based on engagement metrics such as email opens or website visits?

Yes, you can definitely create custom audiences based on engagement metrics such as email opens or website visits. This approach is highly effective for targeting and optimizing your marketing efforts. Here's how you can leverage these engagement metrics to build and refine your custom audiences:

### 1. **Email Engagement-Based Custom Audiences**

**1.1. Segment by Email Opens and Clicks**
   - **Active Subscribers:** Create segments based on users who frequently open or click on your emails. This group is likely highly engaged and interested in your content or offers.
   - **Engaged vs. Inactive:** Differentiate between highly engaged users and those who rarely open your emails. This helps in tailoring your communication strategies—more personalized and frequent messages for engaged users, and re-engagement strategies for inactive ones.

**1.2. Re-engagement Campaigns**
   - **Targeted Promotions:** Use historical email engagement data to create custom audiences for re-engagement campaigns. For instance, target users who haven't interacted with your emails in a while with special offers or updated content to reignite their interest.
   - **Content Personalization:** Tailor the content of your emails based on past engagement metrics, such as sending relevant articles to users who have shown interest in similar topics.

**1.3. Lifecycle Segmentation**
   - **Nurture Sequences:** Design customized email nurture sequences for different segments based on their engagement level, guiding them through the sales funnel with relevant content and offers.

### 2. **Website Visit-Based Custom Audiences**

**2.1. Behavior-Based Segmentation**
   - **Frequent Visitors:** Create custom audiences from users who visit your website frequently or spend significant time on specific pages. This indicates a high level of interest and engagement.
   - **Page Views:** Segment users based on the specific pages they visit (e.g., product pages, blog posts) to tailor your messaging and offers according to their interests.

**2.2. Retargeting Strategies**
   - **Abandoned Cart:** Develop custom audiences of users who have added items to their cart but haven't completed the purchase. Retarget these users with reminders, special offers, or incentives to complete their purchase.
   - **Product Interest:** Target users who have shown interest in specific products or categories with related offers or updates.

**2.3. Engagement Triggers**
   - **Dynamic Content:** Use website behavior data to trigger dynamic content or personalized recommendations based on users' previous interactions and visits.
   - **Custom Alerts:** Set up alerts for specific actions or behaviors, such as visiting high-value pages or multiple product pages, to quickly engage users with relevant offers or information.

### 3. **Integration of Engagement Metrics**

**3.1. Combining Data Sources**
   - **Cross-Channel Insights:** Integrate email engagement data with website visit data to create more comprehensive audience segments. For example, target users who both frequently open emails and visit specific website pages with highly relevant offers.

**3.2. Enhanced Personalization**
   - **Unified Profiles:** Combine engagement metrics with other data (like purchase history or demographic information) to build detailed customer profiles. This helps in delivering highly personalized marketing messages and offers.
