3 options for sending email with Node.js
1. Using SMTP (Ex : Gmail, Mailtrap)-
Simple Mail Transfer Protocol (SMTP) is a technology for sending outgoing emails across networks and is the most common transport method. It serves as a relay service to send email from one server to another.
When you send an email to a friend using an email client like Gmail, an outgoing (SMTP) server picks it up and connects with your friend’s receiving server. The two servers communicate using guidelines defined by the SMTP protocol, determining who the recipient is and how they can receive the incoming mail. Email clients usually have an SMTP server associated with them to aid in email delivery
2. Using an email API (email services) – [ Amazon SES, Postmark, SparkPost, SendGrid, Mailgun, and Mailchimp Transactional (formerly Mandrill) ]
Email services allow you to send email from your app using a hosted API. Instead of managing email servers and their requirements yourself, you can use an email API to handle message assembly, sending, and deliverability. Transactional email APIs come in handy when you need a reliable service that can be integrated quickly, can support high-volume sending, and offers rich functionality.
There are many email services on the market. The most popular ones include Amazon SES, Postmark, SparkPost, SendGrid, Mailgun, and Mailchimp Transactional (formerly Mandrill). All of them are paid services, though most offer free or low-cost introductory plans
3. Using a notification service – (Courier, OneSignal – is a multichannel notifications platform that enables)
With a notification service, you can easily add more channels or even switch your email service provider without having to touch your code. If you wanted to notify users across email, SMS, push, or chat apps like Slack and WhatsApp, you could do that in one fell swoop.
