<\/figure><\/div>\n\n\nPrerequisites<\/h2>\n\n\n\n
Before proceeding you need to have Node-RED installed. You can install Node-RED locally on your computer or on a Raspberry Pi, or on a cloud server. Check the following tutorials:<\/p>\n\n\n\n
- Install Node-RED on Raspberry Pi (works on RPI OS 64-bit)<\/a><\/li>
- Access Node-RED Dashboard from Anywhere using Digital Ocean<\/a><\/li><\/ul>\n\n\n\n
For a quick Node-RED getting started guide, take a look at the following tutorials:<\/p>\n\n\n\n

Install Email Nodes<\/h1>\n\n\n\n
There are Node-RED Nodes you can install that make it easy to send emails using Node-RED.<\/p>\n\n\n\n
Go to Menu<\/strong> > Manage Palette<\/strong> > Install<\/strong>. Search for node-red-node-email<\/span> and install those nodes.<\/p>\n\n\n

<\/figure><\/div>\n\n\nFor more information about the nodes, you can check the following link:<\/p>\n\n\n\n

Now, you should have the email nodes on your Node-RED palette.<\/p>\n\n\n

<\/figure><\/div>\n\n\nSender Email<\/h1>\n\n\n\n
To send emails with Node-RED you need a sender email account. We don\u2019t recommend using your main email account to send emails using Node-RED. If something goes wrong in your flow or if by mistake you make too many requests, you can be banned or have your account temporarily disabled. So, we recommend creating a new email account to send emails or using a secondary email account.<\/p>\n\n\n\n
We\u2019ll use a Gmail.com account to send the emails, but you can use any other email provider. The receiver email can be your personal email without any problem.<\/p>\n\n\n\n
Create a Sender Email Account<\/h2>\n\n\n\n
To create a new Gmail account for sending emails with Node-RED, go to this link<\/a>.<\/p>\n\n\n
\n![\"Gmail](\"https:\/\/i0.wp.com\/randomnerdtutorials.com\/wp-content\/uploads\/2020\/02\/GMAIL-create-a-new-account.png?resize=940%2C602&quality=100&strip=all&ssl=1\")
<\/figure><\/div>\n\n\nCreate an App Password<\/h2>\n\n\n\n
You need to create an app password so that Node-RED can send emails using your Gmail account. An App Password is a 16-digit passcode that gives a less secure app or device permission to access your Google Account. Learn more about sign-in with app passwords here<\/a>.<\/p>\n\n\n\n
An app password can only be used with accounts that have 2-step verification turned on<\/a>.<\/p>\n\n\n\n
- Open your Google Account<\/a>.<\/li>
- In the navigation panel, select Security<\/strong>.<\/li>
- Under \u201cSigning in to Google\u201d, select 2-Step Verification<\/strong> > Get started<\/strong>.<\/li>
- Follow the on-screen steps.<\/li><\/ol>\n\n\n\n
After enabling 2-step verification, you can create an app password.<\/p>\n\n\n\n
- Open your Google Account<\/a>.<\/li>
- In the navigation panel, select Security<\/strong>.<\/li>
- Under \u201cSigning in to Google\u201d, select App Passwords<\/strong>.<\/li><\/ol>\n\n\n

<\/figure><\/div>\n\n\nIn the Select app field, choose mail<\/strong>. For the device, select Other<\/strong> and give it a name, for example, Node-RED. Then, click on Generate<\/strong>. It will pop-up a window with a password that you\u2019ll use in Node-RED to send emails. Save that password<\/strong> (even though it says you won\u2019t need to remember it) because you\u2019ll need it later.<\/p>\n\n\n

<\/figure><\/div>\n\n\nNow, you should have an app password that you\u2019ll use on Node-RED to send the emails.<\/p>\n\n\n

<\/figure><\/div>\n\n\nIf you\u2019re using a different email provider, check what you need to do to create an app password. You should be able to find the instructions with a quick google search \u201cyour email provider name<\/strong> + app password\u201d.<\/p>\n\n\n\n
Gmail SMTP Server Settings<\/h2>\n\n\n\n
If you\u2019re using a Gmail account, these are the SMTP Server details:<\/p>\n\n\n\n
- SMTP Server: smtp.gmail.com<\/li>
- SMTP username: Complete Gmail address<\/li>
- SMTP password: Your Gmail password<\/li>
- SMTP port (TLS): 587<\/li>
- SMTP port (SSL): 465<\/li>
- SMTP TLS\/SSL required: yes<\/li><\/ul>\n\n\n\n
Outlook SMTP Server Settings<\/h2>\n\n\n\n
For Outlook accounts, these are the SMTP Server settings:<\/p>\n\n\n\n
- SMTP Server: smtp.office365.com<\/li>
- SMTP Username: Complete Outlook email address<\/li>
- SMTP Password: Your Outlook password<\/li>
- SMTP Port: 587<\/li>
- SMTP TLS\/SSL Required: Yes<\/li><\/ul>\n\n\n\n
Live or Hotmail SMTP Server Settings<\/h2>\n\n\n\n
For Live or Hotmail accounts, these are the SMTP Server settings:<\/p>\n\n\n\n
- SMTP Server: smtp.live.com<\/li>
- SMTP Username: Complete Live\/Hotmail email address<\/li>
- SMTP Password: Your Windows Live Hotmail password<\/li>
- SMTP Port: 587<\/li>
- SMTP TLS\/SSL Required: Yes<\/li><\/ul>\n\n\n\n
If you\u2019re using another email provider, you need to search for its SMTP Server settings. Now, you have everything ready to start sending emails with Node-RED.<\/p>\n\n\n\n
Sending an Email with Node-RED<\/h1>\n\n\n\n
Drag an email<\/strong> node to the flow.<\/p>\n\n\n
\n![\"Node-RED](\"https:\/\/i0.wp.com\/randomnerdtutorials.com\/wp-content\/uploads\/2022\/11\/node-red-email-node.png?resize=145%2C66&quality=100&strip=all&ssl=1\")
<\/figure><\/div>\n\n\nDrag an inject<\/strong> node to the flow and wire it to the email. The inject<\/strong> node will contain the email content.<\/p>\n\n\n
\n![\"Node-RED](\"https:\/\/i0.wp.com\/randomnerdtutorials.com\/wp-content\/uploads\/2022\/11\/node-red-email-flow.png?resize=381%2C58&quality=100&strip=all&ssl=1\")
<\/figure><\/div>\n\n\nTo learn how we must configure the message for the email<\/strong> node, we can take a look at the email node documentation. Select the email<\/strong> node and then, click on the help<\/strong> icon in the top right corner.<\/p>\n\n\n
\n![\"Node-RED](\"https:\/\/i0.wp.com\/randomnerdtutorials.com\/wp-content\/uploads\/2022\/11\/node-red-help-documentation-icon.png?resize=30%2C31&quality=100&strip=all&ssl=1\")
<\/figure><\/div>\n\n\nYou\u2019ll get information about how to use the node.<\/p>\n\n\n
\n![\"node-red](\"https:\/\/i0.wp.com\/randomnerdtutorials.com\/wp-content\/uploads\/2022\/11\/node-red-email-nodes-documentation.png?resize=295%2C471&quality=100&strip=all&ssl=1\")
<\/figure><\/div>\n\n\nSo, we must set the message content on msg.payload<\/span> and the email subject on msg.topic<\/span>. The recipient can be set in msg.to<\/span> or in the email node (we\u2019ll set it in the email node).<\/p>\n\n\n\n
Double-click the inject<\/strong> node to edit its properties.<\/p>\n\n\n\n
Add the email content on msg.payload<\/span>. You need to set it as a String. Then, add the email subject on the msg.topic<\/span>. It also must be set as a String.<\/p>\n\n\n

<\/figure><\/div>\n\n\nNow, double-click the email <\/strong>node to edit its properties. Insert the recipient email, the sender email, and the corresponding app password you generated previously.<\/p>\n\n\n

<\/figure><\/div>\n\n\nWhen you\u2019re finished, click Done<\/strong>.<\/p>\n\n\n\n
Testing the Flow<\/h1>\n\n\n\n
Now, deploy your application.<\/p>\n\n\n

<\/figure><\/div>\n\n\nAfter deploying click on the left square on the inject<\/strong> node to trigger the email<\/strong> node.<\/p>\n\n\n

<\/figure><\/div>\n\n\nIf everything went as expected, you should have a new email on your recipient account.<\/p>\n\n\n
\n![\"Gmail](\"https:\/\/i0.wp.com\/randomnerdtutorials.com\/wp-content\/uploads\/2022\/11\/receive-email-from-Node-RED.png?resize=1152%2C214&quality=100&strip=all&ssl=1\")
<\/figure><\/div>\n\n\nThat’s it! You learned an easy way to send emails with Node-RED.<\/p>\n\n\n\n
Wrapping Up<\/h2>\n\n\n\n
As you can see, sending emails with Node-RED is very straightforward. We showed you a simple example with an inject node. The idea is to apply this feature in real-world scenarios. We’ll publish more tutorials about this subject, so stay tuned.<\/p>\n\n\n\n
