Thanks for reply, I think that you talk about this plugin GitHub - ChrisRAoW/mautic-rss-to-email-bundle: Mautic plugin to send emails from RSS
and also related to this pull request Add possibility to extend the email form template (edit emails) by ChrisRAoW · Pull Request #10401 · mautic/mautic · GitHub
But is it in 4.2.2 version of Mautic ? I am not sure.
If yes, how to use it ?
@joeyk and @chrisraow have you any feedback related to this ?
