Greetings. To insert Custom post types into the TNP newsletters, please point me to the “Advanced Composer Blocks” add-on. I could not find it anywhere. Is it a premium add-on?
yes, it is a premium addon part of our annual licenses. You can take a look at the full list of the advanced block here: https://www.thenewsletterplugin.com/composer. All our licenses come with a 30 days, no-question-asked refund policy.
Let me know if you have any other questions,
Michael
