Send Mail laravel to multiple recipients by using foreach - laravel

Question

Good evening everyone,
I have some issues in my project. I'm trying to send mail to each collaborator who celebrates his birthday. The data are taken from my database. The problem is that: if I have for example 2 or 3 collaborators who celebrate their birthday in the same day, only the first in the list receive a mail. My question how send to all concerned collaborator a mail.
My code:
public function handle()
{
$collaborateurs = Card::listCard();
foreach ($collaborateurs as $collaborateur) {
return Mail::to($collaborateur->adresse_email)->send(new SendEmail($collaborateur));
}
}
class CarteAnnif {
public static function listCard(){
$collaborateurs = Organigramme::whereMonth('date_de_naissance', now()->month)
->whereDay('date_de_naissance', now()->day)
->get();
$collaborateursConcernes = [];
foreach ($collaborateurs as $collaborateur) {
$date_de_naissance = Carbon::createFromFormat('d/m/Y', $collaborateur->date_de_naissance)->format('d-m');
$date_de_naissance = strtotime($date_de_naissance);
$today = date('d-m');
$today = strtotime($today);
if($date_de_naissance == $today ){
$collaborateursConcernes[] = $collaborateur;
}
}
return collect($collaborateursConcernes);
}
}
public $collaborateur;
public function __construct($collaborateur)
{
$this->collaborateur = $collaborateur;
}
/**
* Build the message.
*
* #return $this
*/
public function build()
{
$this->view('admin.emails.send_card_to_collaborateurs')
->subject("Joyeux anniversaire");
return $this->from('app#domain.com')->view('admin.emails.send_card_to_collaborateurs');
}
}
I hope I have been clear otherwise I remain available for any other additional information
Thanks in advance!

The return ends a function, so your function will stop after the first loop. Just delete the retun :
foreach ($collaborateurs as $collaborateur) {
Mail::to($collaborateur->adresse_email)->send(new SendEmail($collaborateur));
}
