How do I make a subscription box in Acabado?
That box isn’t created in Acabado. Most of the time, whoever you use to host and manage your email list will have options for creating subscription boxes. There are also plugins that will do it. I would use the email list company’s subscription box functionality to create the box and then they’ll give you an embed code. Then, you go into your WordPress dashboard on your site to the Widgets area under “Appearance”. Add a widget for “code” or “custom HTML” and then past the embed code for the subscription box.
This will place that subscription box in the sidebar.
This is the same process you can use for any WordPress theme.
