Sending HTML mail using a shell script

Question

How can I send an HTML email using a shell script?

Answer 1

The tags include 'sendmail' so here's a solution using that:

(
echo "From: me@xyz.com "
echo "To: them@xyz.com "
echo "MIME-Version: 1.0"
echo "Content-Type: multipart/alternative; " 
echo ' boundary="some.unique.value.ABC123/server.xyz.com"' 
echo "Subject: Test HTML e-mail." 
echo "" 
echo "This is a MIME-encapsulated message" 
echo "" 
echo "--some.unique.value.ABC123/server.xyz.com" 
echo "Content-Type: text/html" 
echo "" 
echo "

echo "------some.unique.value.ABC123/server.xyz.com--"
) | sendmail -t

A wrapper for sendmail can make this job easier, for example, mutt:

mutt -e 'set content_type="text/html"' me@mydomain.com -s "subject" <  message.html
