          <spacer size="27"></spacer>

You need to place styles in app.scss (or included files), after that ZURB will be able to make correct inline style. Do not write inline styles manual.

Besides, you need setup babel to convert relative paths to abloluse like as in *.html templates.

.pipe($.if(!!awsURL, $.replace(/('|")(\/?assets\/img)/g, "$1" + awsURL)))

Example for aws:

// Compile Sass into CSS
function sass() {
    var awsURL = !!CONFIG && !!CONFIG.aws && !!CONFIG.aws.url ? CONFIG.aws.url : false;
    return gulp.src('src/assets/scss/app.scss')
    .pipe($.if(!PRODUCTION, $.sourcemaps.init()))
    .pipe($.sass({
      includePaths: ['node_modules/foundation-emails/scss']
    }).on('error', $.sass.logError))
    .pipe($.if(PRODUCTION, $.uncss(
     {
        html: ['dist/**/*.html']
      })))
    .pipe($.if(!PRODUCTION, $.sourcemaps.write()))
    .pipe($.if(!!awsURL, $.replace(/('|")(\/?assets\/img)/g, "$1" + awsURL)))
    .pipe(gulp.dest('dist/css'));
}

and add creds pipe in task. It will look something like this:

// Build emails, then send to EMAIL
gulp.task('mail',
  gulp.series(creds, 'build', aws, mail));

This is necessary to initialize the CONFIG var.
