It is a good idea to use sendmail command to send an html email from a linux or unix server. By using this command the email content will be displayed in HTML format (not just HTML code). In this tutorial I will be covering two options to send HTML email using shell script,
Using SendMail
If you don’t have sendmail installed please install it first. I personally suggest to install sendmail to do this trick.
Save all your HTML content in to a file with some name. For example I am giving the file name as email.html
Add the below content
<h1>This is a test email<h2><b>Mistonline.in one of the largest website tutorial provider</b>
Save this file to some path like /home/admin
Now create a shell script named test_email.sh in path /home/admin and add the below content, Make sure execute permission for test_email.sh file is set accordingly.
Note: Change the To: [email protected] to email address of your choice
#!/bin/sh
host=`hostname`
(echo To: [email protected]
echo From: server@$host
echo "Content-Type: text/html; "
echo Subject: Some Subject
echo
cat email.html ) | sendmail -t
If you do not want a file to be created but just want some html content to be send through email then use the below commands
#!/bin/sh
host=`hostname`
(echo To: [email protected]
echo From: server@$host
echo "Content-Type: text/html; "
echo Subject: Some Subject
echo
echo "<h1>This is a test email<h2><b>Mistonline.in one of the largest website tutorial provider</b>" ) | sendmail -t

Using mail
If you don’t have sendmail installed then try using the mail command.
Send HTML email in a single mail command
# mail -a "Content-type: text/html" -s "Testing HTML Email" [email protected] << EOF
<html><h2>This is a test email</h2><a href="https://mistonline.in">Click Here</a></html>
EOF
Here,
-a, –append=HEADER: VALUE append given header to the message being sent
-s, is the subject of the email
Send HTML email by appending HTML file in the mail command
mail -a "Content-type: text/html" -s "Testing HTML Email" [email protected] < email.html
In the above command email.html contains the HTML format we are intending to send as an email.
Make sure to replace [email protected] to the email address of your choice.
