Hello, I have the version of mautic 4.2.1 and the customize slot option does not appear, making it “more difficult to write and format the text”
and I see in videos un Youtube people with this … Could you please tell me how to activate that option?
Did you mean, that you can’t customize the text in the grapesjs editor?
The screenshot is from the old e-mail builder.
To see it you have to deactivate the “GrapeJS Builder” plugin and create a new e-mail.
Nevertheless I advise you not to use it because it is not maintained anymore.
