I created an email signature with Hubspot generator and copied the code to an HTML editor. Can I save the HTML file and use it on other platforms (e.g. Office email templates folder)? In the HTML there are classes, I believe it can be deleted if I'm not using the Hubspot platform, is this correct? Thanks
