Allow placing the Checkmk logo at the bottom of HTML notification emails

Hello,

I would like to suggest a small improvement to the "Parameters for Email (HTML)" notification method.

Currently, the generated HTML emails always place the Checkmk logo at the very beginning of the email body. While this looks nice in the email itself, it has an unwanted side effect on some mail clients.

For example, on Apple Mail for iPhone, the email preview uses the first text elements of the HTML message. Since the logo's alt text ([Checkmk Logo]) appears first, every notification preview starts with:

[Checkmk Logo]

instead of immediately showing the relevant monitoring information, such as the event, host or service.

As a result, the notification list becomes much harder to scan quickly, especially when receiving many alerts.

Proposed enhancement

Please add an option to the "Parameters for Email (HTML)" notification method to control the logo position, for example:

Logo at the top (current behavior, default)
Logo at the bottom
No logo

Moving the logo to the bottom would preserve the existing branding while allowing the notification preview in mail clients such as Apple Mail to begin with the most important information.

This would improve readability without changing the default behavior, so existing installations would not be affected.

Thank you for considering this enhancement.

Best regards
