With Garagist.Plaintext you can convert any HTML or MJML document to plaintext. Useful for newsletter generation.
Add the package in your site package:
composer require --no-update garagist/plaintextThe run composer update in your project root.
To hide an element, add the class plaintext:hidden to remove it from the plaintext output. To mark an MJML element as headline (aka convert to uppercase), add the css-class plaintext:uppercase.
