Using Smtp2Go with Node.js

Sometimes you need a way to send email based on some automatisms or you need to send a bulk of emails without relying on external SaaS for some reasons.
SMTP2Go is a neat service to send email programmatically by calling regular RESTfull API over the network. The service is kind enough to provide a free plan for those who don't have to send a massive amount of emails.
Using Node.js together with it is quite trivial. A simple module, let's say sender.js might be filled with this code:
const request = require('request')
var smtpurl = 'https://api.smtp2go.com/v3/email/send'
var smtpob = (name, email) => {
return {
'api_key': 'your-api-key',
'to': [`${name} <${email}>`],
'sender': 'My Company <hello@example.com>',
'subject': 'A Subject',
'text_body': 'some text'
}
}
module.exports = function () {
function send (name, email) {
var src = smtpob(name, email)
request
.post({
headers: {'content-type': 'application/json'},
url: smtpurl,
body: JSON.stringify(src)
})
.on('response', function (response) {
if (response.statusCode !== 200) {
console.log(response.statusCode)
console.log(response.statusMessage)
}
})
.on('data', function (data) {
console.log('decoded chunk: ' + data)
})
.on('error', function (err) {
console.log('Email sender', err)
})
}
return {send: send}
}
Now, in order to use with your content, go to create an index.js file with:
var sender = require('./sender.js')()
sender.send('Fabio', 'hello@gmail.com')
By running this script I'll receive a message from it (please, change the email before using it!).
If you want to use this service in the right way, don't forget to configure properly the SPF record in your DNS to avoid to be caught by spam filters.
