New WordPress Site email should be configurable

[123host]

I am a server administrator at a web hosting company.

When using the WP toolkit and WP is automatically installed, an email is send to the user

Your new WordPress site has been successfully set up at:

https://example.com

You can log in to the administrator account with the following information:

Username: admin_example
Password: The password you chose during installation.
Log in here: https://example.com/wp-login.php

We hope you enjoy your new site. Thanks!

This is useful, but it seems obvious that a web host or perhaps a developer would like to customise this email so that it is white labelled and more personal.

A grep search shows the string "New WordPress Site" in

wp-includes/ms-functions.php
wp-admin/includes/schema.php
wp-admin/includes/upgrade.php

The ​update_welcome_email filter can be used to modify the body of this email. I think this can be closed as worksforme.

How can I modify a filter in an install before it has happened? The install happens, the email is sent straight away. What is the point of then adding a filter to modify the email?

@123host In order to use this filter you need to hook into the wp_filter global inside a file that loads during the installation, usually wp-config.php. This approach is documented here for another filter that runs before plugins have a chance to hook in: ​https://developer.wordpress.org/reference/hooks/enable_wp_debug_mode_checks/

I'll add the same note to this filter for future reference. Cheers!
