send emails, html and attachments (files, streams and strings) from node.js to any smtp server
npm install emailjs - works with SSL and TLS smtp servers
- supports smtp authentication ('PLAIN', 'LOGIN', 'CRAM-MD5', 'XOAUTH2')
- emails are queued and the queue is sent asynchronously
- supports sending html emails and emails with multiple attachments (MIME)
- attachments can be added as strings, streams or file paths
- supports utf-8 headers and body
- built-in type declarations
- automatically handles greylisting
- auth access to an SMTP Server
- if your service (ex: gmail) uses two-step authentication, use an application specific password
