Does that help?

Hey @kriziadg !

We don’t currently support the ability to include checkboxes in your template, but there are a few workarounds.

The first option is to use buttons to collect information about your customers. You can view our Help Doc here: https://help.klaviyo.com/hc/en-us/articles/115005255248-How-to-Use-Buttons-to-Collect-Information-About-Your-Recipients

I think this option is good for a single question, but I wouldn’t recommend using it 4+ times in your template.

Instead, I would recommend directing users to a preference page as you described! If using a button block to link users to the preference page, you can do this with the tag: 

{% manage_preferences_link %}

The only thing to keep in mind is that if you’re sending this content in your welcome flow, and that flow is triggered by a list, then you’ll need to make sure you update the list preference page. This is not the same as the global “Preference Pages” for your account.
