Hello Team,
Could you please share if it is possible to have color coding while sending email via Watcher?
Like if OK = the cell should be Green in the table which is sent via Watcher & for NOT OK = Red.
I tried but it seems the style parameters are being dropped even tried updating the elasticsearch.yml with below config but it did not help :
```auto
xpack.notification.email.html.sanitization.allow: _tables, _blocks, _formatting, _links, img:embedded
xpack.notification.email.html.sanitization.disallow: script, style
```
Any pointers on how to proceed or if it is possible or not?
Thank you !

Could you post a watch that reproduces this? Have you tried setting `xpack.notification.email.html.sanitization.enabled` to false, just to see if that solves the problem (I understand that you probably don't want to do that in production, but I'm just curious if it solves the problem).

Thank you @Keith_Massey
Yes, using this option color coding works as required. But how to make it happen in Production?
Thanks!!

I'm not sure yet. Can you post a watch that reproduces this?

You need to add `_styles` to your 'allow' setting as documented [here](https://www.elastic.co/guide/en/elasticsearch/reference/8.18/notification-settings.html#email-notification-settings).

Thanks @angelo for the suggestion.
Using styles , i confirm it is working as expected.
`xpack.notification.email.html.sanitization.allow: _tables, _formatting, _styles`
Thanks!!
