Changing Alert Emails from Dark Mode

Grafana Alerting

Hi all,

Update from 9.4.3 to 9.5.1 few weeks ago and had Alert Emails not sending

I editted the ng_alert_notification.html before to suit light mode and then updated and got
“Got 2 out of expected 3 arguments” or similar error, didn’t have time to check the missing piece yet, will do

But my question is, apart from editing colour settings of headings and body in html is there a way to change to lightmode alerts

Also I have light mode on for Grafana in general so it must just default the email to dark mode

I’m having the same issue too - would like all of my alerts – email, Teams to be light mode. Dark mode plays havoc when trying to forward to someone - results in black text on black background. There must be a simple switch, or similar, rather than having to hack up ng_alert_notifications. @georgerobinson

I’m afraid just dark mode is supported at present. If forwarding emails from Grafana is important, and images are not required, I’d recommend telling Grafana to send plain text emails instead.

For example:

You have 1 firing alert(s), and 0 resolved alert(s) for alertname=Test, grafana_folder=Test Folder

(1) FIRING
-----------

Labels: alertname=Test, grafana_folder=Test Folder
Summary: This is a summary
Description: This is a description

If using plain text emails I would recommend upgrading to the latest version of Grafana 10 as I’ve done work in Grafana 10.0.1 to 1. improve the default template and 2. support templating of plain text emails.

Here is an example of how to turn on plain/text emails in Grafana’s ini file:

[emails]
welcome_email_on_sign_up = false
templates_pattern = emails/*.html, emails/*.txt
content_types = text/plain
