Email Sending using Aspose.Email Cloud in Heroku Node.js App

A tutorial on how to setup a heroku node.js app, and how to use Aspose.Email Cloud for email sending in Node.js application.

This blog guides you through deploying a Node.js app on Heroku and using Aspose.Email Cloud for email sending. It assumes you already have a free Heroku account and that Node.js and NPM are installed locally. Let’s get started!

Setup Heroku

First, install the Heroku Command Line Interface (CLI). The CLI lets you manage apps, provision add‑ons, view logs, and run your app locally. macOS users can install it via Homebrew, or you can download it from the official Heroku site.

brew install heroku/brew/heroku

After installation, authenticate the CLI:

heroku login
heroku: Press any key to open up the browser to login or q to exit
 ›   Warning: If browser does not open, visit
 ›   https://cli-auth.heroku.com/auth/browser/***
heroku: Waiting for login...
Logging in... done
Logged in as me@example.com

This opens your browser to the Heroku login page, which is required for both Heroku and Git commands to work correctly.

Setup Aspose.Email Cloud

Aspose.Email Cloud is a SDK that lets you send, receive, append, flag, and convert emails in the cloud, as well as create folder structures for email archiving. It works without additional software and supports many languages, including C#, Java, PHP, Python, Ruby, and TypeScript. Follow the official guide to install the SDK here.

Email Sending using Aspose.Email Cloud

Assuming Node.js is installed, create a project folder:

$ mkdir my-email-sending-app
$ cd my-email-sending-app
$ npm init
$ npm install express --save
$ npm install @asposecloud/aspose-email-cloud

Add the following code to main.js:

Deploy Node.js App to Heroku

When your changes are ready, push the app to Heroku:

$ heroku create
Creating sharp-rain-871... done, stack is heroku-18
https://sharp-rain-871.herokuapp.com/ | https://git.heroku.com/sharp-rain-871.git
Git remote heroku added

This creates a Git repository on Heroku. Deploy by pushing your code:

$ git push heroku main

Open the live app with:

heroku open
