    Node-RED nodes to send and receive simple emails.


    You will need valid email credentials for your email server. For GMail this may mean getting an application password if you have two-factor authentication enabled.

    Note : Version 1.x of this node requires Node.js v8 or newer.


    You can install by using the Menu - Manage Palette option, or running the following command in your Node-RED user directory - typically ~/.node-red

        cd ~/.node-red
        npm i node-red-node-email

    GMail users

    If you are accessing GMail you may need to either enable an application password, or enable less secure access via your Google account settings.


    Nodes to send and receive simple emails.

    Input node

    Fetches emails from an IMAP or POP3 server and forwards them onwards as messages if not already seen.

    The subject is loaded into msg.topic and msg.payload is the plain text body. If there is text/html then that is returned in msg.html. msg.from and are also set if you need them.

    Additionally msg.header contains the complete header object including to, cc and other potentially useful properties.

    Output node

    Sends the msg.payload as an email, with a subject of msg.topic.

    The default message recipient can be configured in the node, if it is left blank it should be set using the property of the incoming message. You can also specify any or all of:, msg.bcc, msg.replyTo, msg.inReplyTo, msg.references, msg.headers, or msg.priority properties.

    The email from can be set using msg.from but not all mail services allow this unless msg.from is also a valid userid or email address associated with the password. Note: if userid or msg.from does not contain a valid email address (, you may see (No Sender) in the email.

    The payload can be html format. You can also specify msg.plaintext if the main payload is html.

    If the payload is a binary buffer then it will be converted to an attachment.

    The filename should be set using msg.filename. Optionally msg.description can be added for the body text.

    Alternatively you may provide msg.attachments which should contain an array of one or more attachments in nodemailer format.

    If required by your recipient you may also pass in a msg.envelope object, typically containing extra from and to properties.

    If you have own signed certificates, Nodemailer can complain about that and refuse sending the message. In this case you can try switching off TLS.

    Use secure connection - If enabled the connection will use TLS when connecting to server. If disabled then TLS is used if server supports the STARTTLS extension. In most cases set this to enabled if you are connecting to port 465. For port 587 or 25 keep it disabled.

    This node uses the nodemailer npm module.
