emailjs 
send emails, html and attachments (files, streams and strings) from node.js to any smtp server
INSTALLING
npm install emailjs
FEATURES
- 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
REQUIRES
- auth access to an SMTP Server
- if your service (ex: gmail) uses two-step authentication, use an application specific password
EXAMPLE USAGE - text only emails
import { client as c } from 'emailjs';
const client = new c.Client({
user: 'user',
password: 'password',
host: 'smtp.your-email.com',
ssl: true
});
// send the message and get a callback with an error or details of the message that was sent
client.send({
text: 'i hope this works',
from: 'you <username@your-email.com>',
to: 'someone <someone@your-email.com>, another <another@your-email.com>',
cc: 'else <else@your-email.com>',
subject: 'testing emailjs'
}, (err, message) => {
console.log(err || message);
});
EXAMPLE USAGE - html emails and attachments
import { client as c } from 'emailjs';
const client = new c.Client({
user: 'user',
password: 'password',
host: 'smtp.your-email.com',
ssl: true
});
const message = {
text: 'i hope this works',
from: 'you <username@your-email.com>',
to: 'someone <someone@your-email.com>, another <another@your-email.com>',
cc: 'else <else@your-email.com>',
subject: 'testing emailjs',
attachment: [
{ data: '<html>i <i>hope</i> this works!</html>', alternative: true },
{ path: 'path/to/file.zip', type: 'application/zip', name: 'renamed.zip' }
]
};
// send the message and get a callback with an error or details of the message that was sent
client.send(message, function(err, message) { console.log(err || message); });
// you can continue to send more messages with successive calls to 'client.send',
// they will be queued on the same smtp connection
// or instead of using the built-in client you can create an instance of 'smtp.SMTPConnection'
EXAMPLE USAGE - sending through outlook
import { client as c, message as m } from 'emailjs';
const client = new c.Client({
user: 'user',
password: 'password',
host: 'smtp-mail.outlook.com',
tls: {
ciphers: 'SSLv3'
}
});
const message = new m.Message({
text: 'i hope this works',
from: 'you <username@outlook.com>',
to: 'someone <someone@your-email.com>, another <another@your-email.com>',
cc: 'else <else@your-email.com>',
subject: 'testing emailjs',
attachment: [
{ data: '<html>i <i>hope</i> this works!</html>', alternative: true },
{ path: 'path/to/file.zip', type: 'application/zip', name: 'renamed.zip' }
]
});
// send the message and get a callback with an error or details of the message that was sent
client.send(message, (err, message) => {
console.log(err || message);
});
EXAMPLE USAGE - attaching and embedding an image
import { client as c, message as m } from 'emailjs';
const client = new c.Client({
user: 'user',
password: 'password',
host: 'smtp-mail.outlook.com',
tls: {
ciphers: 'SSLv3'
}
});
const message = new m.Message({
text: 'i hope this works',
from: 'you <username@outlook.com>',
to: 'someone <someone@your-email.com>, another <another@your-email.com>',
cc: 'else <else@your-email.com>',
subject: 'testing emailjs',
attachment: [
{ data: '<html>i <i>hope</i> this works! here is an image: <img src="cid:my-image" width="100" height ="50"> </html>' },
{ path: 'path/to/file.zip', type: 'application/zip', name: 'renamed.zip' },
{ path: 'path/to/image.jpg', type: 'image/jpg', headers: { 'Content-ID': '<my-image>' } }
]
});
// send the message and get a callback with an error or details of the message that was sent
client.send(message, (err, message) => {
console.log(err || message);
});
API
new client.Client(options)
// options is an object with the following keys
options =
{
user // username for logging into smtp
password // password for logging into smtp
host // smtp host
port // smtp port (if null a standard port number will be used)
ssl // boolean or object {key, ca, cert} (if true or object, ssl connection will be made)
tls // boolean or object (if true or object, starttls will be initiated)
timeout // max number of milliseconds to wait for smtp responses (defaults to 5000)
domain // domain to greet smtp with (defaults to os.hostname)
authentication // array of preferred authentication methods ('PLAIN', 'LOGIN', 'CRAM-MD5', 'XOAUTH2')
logger // override the built-in logger (useful for e.g. Azure Function Apps, where console.log doesn't work)
}
client.Client#send(message, callback)
// message can be a smtp.Message (as returned by email.message.create)
// or an object identical to the first argument accepted by email.message.create
// callback will be executed with (err, message)
// either when message is sent or an error has occurred
new message.Message(headers)
// headers is an object ('from' and 'to' are required)
// returns a Message object
// you can actually pass more message headers than listed, the below are just the
// most common ones you would want to use
headers =
{
text // text of the email
from // sender of the format (address or name <address> or "name" <address>)
to // recipients (same format as above), multiple recipients are separated by a comma
cc // carbon copied recipients (same format as above)
bcc // blind carbon copied recipients (same format as above)
subject // string subject of the email
attachment // one attachment or array of attachments
}
message.Message#attach
// can be called multiple times, each adding a new attachment
// options is an object with the following possible keys:
options =
{
// one of these fields is required
path // string to where the file is located
data // string of the data you want to attach
stream // binary stream that will provide attachment data (make sure it is in the paused state)
// better performance for binary streams is achieved if buffer.length % (76*6) == 0
// current max size of buffer must be no larger than Message.BUFFERSIZE
// optionally these fields are also accepted
type // string of the file mime type
name // name to give the file as perceived by the recipient
charset // charset to encode attatchment in
method // method to send attachment as (used by calendar invites)
alternative // if true, will be attached inline as an alternative (also defaults type='text/html')
inline // if true, will be attached inline
encoded // set this to true if the data is already base64 encoded, (avoid this if possible)
headers // object containing header=>value pairs for inclusion in this attachment's header
related // an array of attachments that you want to be related to the parent attachment
}
new smtp.SMTPConnection(options)
// options is an object with the following keys
options =
{
user // username for logging into smtp
password // password for logging into smtp
host // smtp host
port // smtp port (if null a standard port number will be used)
ssl // boolean or object {key, ca, cert} (if true or object, ssl connection will be made)
tls // boolean or object (if true or object, starttls will be initiated)
timeout // max number of milliseconds to wait for smtp responses (defaults to 5000)
