Add a toRecipient method to allow sending mail notifications to a different email without overriding routeNotificationForMail method

[sts-ryan-holton]

I have a Laravel 10 project which allows a user to customise the email address that should receive alerts from my system. This, right now is done by overriding the routeNotificationForMail method on my User model. However, when the user types in a different email address that isn't their account's email address, important emails such as password resets and other emails are sent to this notification email which may not be their account's email address and thus means users cannot reset their passwords.

I only really need to override the email that should receive alerts in my toMail method of some notifications, but I don't see anywhere where this is supported by Laravel? Here's one of my toMail method in a DomainExpiry notification class:

/**
 * Get the mail representation of the notification.
 *
 * @param  mixed  $notifiable
 */
public function toMail($notifiable)
{
    $domain = isset($this->emailData[0]['domain']) ? $this->emailData[0]['domain'] : '';
    $domain = htmlspecialchars($domain);

    $data = [
        'is_subscribed' => $notifiable->is_subscribed,
        'first_name' => $notifiable['first_name'],
        'domains' => json_encode($this->emailData),
    ];

    try {
        $this->createHistoryEntry('mail', 'Domain Expiry', $data, $notifiable);
    } catch (\Exception $e) {
    }

    return (new MailMessage)
                ->subject(isset($domain) && ! empty($domain) ? "Domain Expiry Alert: $domain" : 'Domain Expiry Alert')
                ->markdown('emails.domains.expiry', $data);
}

And here's the method overrideen on the User model:

/**
 * Route notifications for the mail channel.
 *
 * @return array|string
 */
public function routeNotificationForMail(Notification $notification)
{
    return $this->notification_email;
}

How do I customise the recipient without sending important alerts to this notification_email field?

Is there a way to fetch the user model into the toMail and set a recipient right on:

return (new MailMessage)
            ->subject('My subject')
            ->markdown('emails.domains.expiry', $data);

Maybe there's a toRecipient method?

You can return a full Mailable. See Using Mailables section.

@Angel5a cool! And this would allow me to use markdown etc?

Yes it is.
