When trying to create an amp email, it is appending ="" to the attribute in the tag. How can you prevent that?

< html ⚡4email="" lang="en" >

It's coming from the PostHTML renderer I think, will check if there's an option to prevent that.

Meanwhile, if it's a problem, you could just replace that string after the template is compiled:

// config.production.js
module.exports = {
  replaceStrings: {
    '⚡4email=""': '⚡4email',
  }
}

So there's quoteAllAttributes in PostHTML, which can be set to false like this in Maizzle:

// config.production.js
module.exports = {
  build: {
    posthtml: {
      options: {
        quoteAllAttributes: false
      }
    }
  }
}

...but I wouldn't recommend doing it because it'll remove attribute quotes wherever it can, so you end up with stuff like:

<table style="width: 100%;" cellpadding=0 cellspacing=0 role=presentation>

Which should be mostly fine if you're not using an XHTML doctype (why would you?), but I'm not sure what happens with those in quirks mode, which is quite common in email (email clients strip your doctype so it doesn't interfere with theirs, i.e. Gmail web, Thunderbird etc).

There's a PR to PostHTML's parser that might fix this.
