# `message:append_text_html(content)`
|
|
|
|
{{since('dev')}}
|
|
|
|
Identifies the primary `text/html` part of the message, decodes its transfer
|
|
encoding, and locates the closing `"</body>"` or `"</BODY>"` tag. If the tag
|
|
is found, `content` is inserted ahead of it. If no body tag is found, appends the
|
|
`content` string to the part. The part is then re-transfer-encoded and the
|
|
message data is updated.
|
|
|
|
This is useful for example to add a tracking pixel into the message:
|
|
|
|
```lua
|
|
umo.on('smtp_server_message_received', function(msg)
|
|
local my_tracking_link =
|
|
'<img src="http://10.0.0.1/img_tracker.jpg" alt="open tracking pixel">'
|
|
msg:append_text_html(my_tracking_link)
|
|
end)
|
|
```
