3. Create Dynamic Content in Klaviyo Emails
1. Using Dynamic Tags
Insert dynamic tags directly into your email content:
html
CopyEdit

This pulls the customer’s first name automatically from their profile data.
2. Setting Conditional Logic
Go to the Email Editor in Klaviyo.
Drag a Text Block into your email template.
Click Personalize and choose Conditional Logic.
html
CopyEdit
{% if person|lookup:'favorite_color' == 'Blue' %} Check out our blue collection, just for you! {% else %} Discover our best sellers today! {% endif %}
Tip: Use conditional logic to show different products or offers based on customer preferences.
4. Use Segmentation to Send Personalized Campaigns
Navigate to Lists & Segments in Klaviyo.
Click Create List / Segment and select Segment.
Define your segment using filters such as:
Purchase Behavior: "Has purchased product X in the last 30 days."
Engagement Level: "Opened email in the last 7 days."
Custom Properties: "Favorite Category is Skincare."
Example: Create a segment of VIP customers who have spent over $500 and send them exclusive offers.
5. Automate Personalization with Flows
Go to Flows in Klaviyo.
Select Create Flow and choose from pre-built templates or start from scratch.
Use Triggers such as Added to Cart or Abandoned Checkout.
Add Email Actions with personalized content based on customer behavior.
