inliner seems to remove font @import

I'm new at this, so I apologize in advance for my ignorance.

I'm attempting to import a google font by including the following in my app.scss:
@import url(http://fonts.googleapis.com/css?family=Raleway:300,400,500,700,600);
@import 'settings';
@import 'foundation-emails';
@import 'local'

I'm using foundation emails 2.2.1 with the following dependencies:
"babel-core": "^6.3.26",
"babel-preset-es2015": "^6.3.13",
"babel-register": "^6.7.2",
"beepbeep": "^1.2.0",
"browser-sync": "^2.11.0",
"colors": "^1.1.2",
"gulp": "git+https://github.com/gulpjs/gulp.git#4.0",
"gulp-awspublish": "^3.0.1",
"gulp-cli": "^1.1.0",
"gulp-html-src": "^1.0.0",
"gulp-htmlmin": "^1.1.1",
"gulp-if": "^2.0.0",
"gulp-imagemin": "^2.4.0",
"gulp-inline-css": "^3.0.0",
"gulp-litmus": "0.0.7",
"gulp-load-plugins": "^1.1.0",
"gulp-rename": "^1.2.2",
"gulp-replace": "^0.5.4",
"gulp-sass": "^2.1.0",
"gulp-sourcemaps": "^1.6.0",
"gulp-zip": "^3.2.0",
"inky": "^1.3.6",
"lazypipe": "^1.0.1",
"merge-stream": "^1.0.0",
"panini": "^1.3.0",
"rimraf": "^2.3.3",
"siphon-media-query": "^1.0.0",
"yargs": "^4.1.0"

I can see the import in the app.css:
@import url(http://fonts.googleapis.com/css?family=Raleway:300,400,500,700,600);

But when the final index.html is created, the font import is missing.

Is it being removed by the inliner?
