I'm using MailPoet within my WordPress website and currently it's only optional for me to send a weekly newsletter (cron job or on user's entrance) based on categories only.
All my posts are tagged with different ACF fields as well, and I was wondering if it's somehow possible to 'hook' mailpoet's functionality based on chosen acf's and not only categories.
I dont have any code to provide but MailPoet's GitHub repository link page.
