@asaadfilho Thanks for the tag, I somehow missed the post notifications.
@buttermilkbysam and @theladycatelyn Sorry for the delay. In general, it’s best to start your own thread, because questions and site details diverge and become unique.
Generally speaking, our plugin options affect the raw RSS feed. Mailchimp then often strips out a lot of those options and the styling itself, requiring it’s own custom CSS, mentioned above. Mailchimp CSS is added in Mailchimp, in the email template at the very top is best, using the <> code icon.
Be sure the Resize images in unchecked on the Mailchimp RSS URL page, and if Medium is still not displaying well, try Large or Full. If you change the Medium dimensions, you have to rebuild your thumbnails (there are a few plugins for that) for that new dimensions to take effect on already uploaded images.
The Excerpt setting is in WordPress under Settings > Reading, choosing Summary or Full, as well as the number of posts in the raw feed.
The Mailchimp merge tag for showing the excerpt would be RSSITEM:CONTENT, and the full text (regardless of the WordPress setting I belive) is RSSITEM:CONTENT_FULL.
The length of the excerpt is controlled by WordPress default value of 55 words, and the theme may have an option to change that as well, but the “Advanced Excerpt” plugin can customize many things regarding the excerpt as well. I will look into adding an option to our plugin for changing the excerpt length so that it’s built-in, to bring more value to the plugin and not require additional work to get the feed looking the way you want.
I will also look into adding an option “Include Mailchimp CSS” for including some default Mailchimp custom CSS according to the plugin options set, and look into other services as well.
