Usage guide
Step 1: Create a dynamic image template on Wafrow
Use an existing image template or create your first on Wafrow.
Step 2: Embed dynamic images within the customer.io email or push notification designer
In your email or push notification designer in Customer.io, add a new Image and select the "dynamic image" checkbox.
In the URL, you can add the image template and the properties linked to the customer. For instance,
https://wafrow.com/i/TEMPLATE_ID?LAYER_NAME[PROPERTY_NAME]={{CUSTOMER_IO_PROPERTY_VALUE}}
In real usage like the screenshot above, it looks like this:
https://wafrow.com/i/9e5c3920-c52b-49e6-93fb-c5333f2ad1fb?firstname[text]={{customer.first_name}}
Here is a preview for two sample users, Elena and David.
This example uses custom properties ("firm" and "logo") that were added to the user profiles in Customer.io. These are then used in the image URL:
https://wafrow.com/i/9ee6bbbc-2c88-444b-b9f3-f1d6a56d8111?firstname[text]={{customer.firm}}&logo[src]={{customer.logo}}
You can create a high degree of personalization for all your Customer.io campaigns with this setup.
Happy exploring!
