    public function send(EmailableInterface $to): int
    {
        $message = $this->messageFactory->createMessage($to->getEmail(), $this->templateName, ['receiver' => $to]);

It seems like $to->getEmail() can also be of type null; however, parameter $email of FSi\Bundle\AdminSecurityBundle\Mailer\SwiftMessageFactoryInterface::createMessage() does only seem to accept string, maybe add an additional type check?

        $message->setFrom($this->fromEmail);
        if (null !== $this->replayToEmail) {
            $message->setReplyTo($this->replayToEmail);
        }

        return $this->mailer->send($message);
    }
}
