Hi! 

Welcome to the community! You definitely can :)

Here’s the attribute name to change the fonts in the modal (you can find more info of what parameters can be modified at the help page article - How to Install Back in Stock for Shopify):

For the button, you can add a class to the button as one of the parameters and the modify the css in your theme to choose what font you want to match your store styling:

Hope that helps!

Hi @Mailbox Manny, this same option isn’t listed in the documentation for BigCommerce (which is what I’m working in) is this still possible to edit?

Thanks! 

Ahhh.. should be possible still.  Test it out :)

If it doesn’t, you should be able to add custom css to your theme and override the klaviyo attributes:

Let me know if it works out, I’d be curious (I’ve only done work on Shopify stores)
