listmonk Web views of campaigns created with visual editor are not mobile-responsive due to missing viewport meta tag

Version:

listmonk: [v5.1.0 Docker]
OS: [Ubuntu 24.04.2 LTS]

When viewing campaigns created with visual editor on mobile devices, the content doesn't scale properly, making it difficult to read.

Campaign web views created with visual editor (accessed via /campaign/:campUUID/:subUUID) are not mobile-responsive because they lack the viewport meta tag in the HTML <head> section.

The head section is empty:

<html>
<head></head>
<body>...

With meta tag:

<html>
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1">
  </head>
<body>...

Hi @drlogout

You can add the meta tag yourself in Admin -> Templates

Unfortunately this is not possible for a "Visual Template". There is no option to edit the HTML of the template (first image) like for the standard/HTML templates (second image).
