You will have to add a tag as well for the link to work

1. Passing user id as to also should work with shortcode
2. Which plugin you are using for this profile structure? You can ask their support to know how we can get user id in that profile page.

Currently we support wordpress roles to send announcement.
May be in future, we may support other 3rt party plugins.

You can follow https://www.shamimsplugins.com/docs/front-end-pm/getting-started/show-unread-message-count-in-menu/ to get an idea

You can use https://www.shamimsplugins.com/docs/front-end-pm/shortcode/fep_shortcode_new_message_form/ , You can pass “to” with this shortcode.

You can uncheck Dashboard > Settings > Discussion > Avatar Display

Please follow https://www.shamimsplugins.com/docs/front-end-pm-pro/getting-started-2/translate/

Can you provide a screenshot of that page so that we can have an idea?

You can get an idea from https://www.shamimsplugins.com/docs/front-end-pm/customization/send-welcome-message-user-register/ (instead of registration, you can use woocommerce hooks to send message).

You can use https://www.shamimsplugins.com/docs/front-end-pm-pro/getting-started-2/role-to-role-block/ for this (available in PRO version)

add following code in your theme’s (child theme’s if your are using) functions.php

add_filter( 'fep_menu_buttons', function( $menu ){
	unset( $menu['newmessage'] );
	return $menu;
}, 99 );

Thank you for your suggestion.
In future i may create this type of plugin.

if you use any caching plugin make sure to clear all cache.
This plugin deletes everything in that checkbox is checked.
If users’ have open tab when this plugin was installed, then you uninstalled this plugin but users are still in that page, then notification url will be hit, untill user refresh or move to another page. As css files are also get hits, it seems you are using any caching plugin where this url is loaded.

Clear all caches and wait some time should fix all your questions.
