Mail Preview

Preview your Nodemailer emails in your browser (Inspired by Letter Opener).

Build Status


  1. Install via npm

     $ npm install mail-preview
  2. Use it with Nodemailer

     var nodemailer = require('nodemailer');
     var path = require('path');
     var tmpdir = path.join(__dirname, 'tmp', 'nodemailer');
     var transport = nodemailer.createTransport('MailPreview', {
       dir: tmpdir,  // defaults to ./tmp/nodemailer
       browser: true // open sent email in browser (mac only, defaults to true)

    Any emails sent through the MailPreview transport will be written to the tmpdir and opened in a browser (unless browser is set to false).
