Hey @pravin ! I’d be happy to help you out here.

First, you’ll need to upload these properties to user profiles. You can upload a CSV file with 3 columns: one for email, and then one for each of the two properties you’re looking to insert to your template.

Once these properties have been added to customer profiles, you can insert them into your template by using the tag:

{{ person|lookup:'NAME_OF_YOUR_PROPERTY' }}

@pravin if they are generic you could also upload giftcodes in Klaviyo and use the variable for the dynamic assignment of discount codes. You need to have enough coupon codes for each recipient of the campaign.

Thank you ksanfelipe and @Omar.

I am planning to use the variable and insert property in the email editor.

I am attaching the screenshot for details.
