@littlerchicken Thank you for confirming!
Actually I found that I checked the option to create a new feed url
https://runthealps.com/feed/email
Can someone with MailChimp experience let me know if this output is ideal for fixing the mega image size issue.
Thank you
BTW I also made sure the MailChimp checkbox to resize images for me is un-checked as the documentation for this plugin suggests.
Thank you. ACF Docs could use this!
