Hi Rose!
I contacted the author and he told me that if I buy his pro version, I will be able to change the emails, but it doesn’t seem logical to me because your editor is much better. I’ve been looking this topic -> https://www.8theme.com/topic/built-in-email-builder-woo-subscription-email-templates-are-missing/, and I see that the editor can be integrated with emails from other plugins, but it’s an old post and most of the images are not visible, so I don’t know what to do.
If I send a test mail from your builder, it works fine and shows the design created with your template.
Thank you so much for your help.
Best regards.
