Thank you for the reply.
but the checkbox still doesn’t work.(The other forms work.)

Controller (shortened)

 $data = [
            'name'  => get('name'),
            'company'  => get('company'),
            'email' => get('email'),
            'text'  => get('text'),
            'city' => get('city'),
            'state' => get('state'),
            'postalcode' => get('postalcode'),
            'country' => get('country'),
            'when' => get('when'),
            'howlong' => get('howlong'),
            'source' => get('source'),
            'target' => get('target'),
            'type'   => get('type') /****** here ******/
        ];

…

 if (empty($alerts)) {
            try {
                $kirby->email([
                    'template' => 'email',
                    'from'     => 'mymail@gmail.com',
                    'replyTo'  => $data['email'],
                    'to'       => 'mymail@gmail.com',
                    'subject'  => esc($data['name']) . ' a message from website',
                    'data'     => [
                        'name'  => esc($data['name']),
                        'type' => esc($data['type']), /****** here ******/
                        'company'  => esc($data['company']),
                        'email'  => esc($data['email']),
                        'city'  => esc($data['city']),
                        'state'  => esc($data['state']),
                        'postalcode'  => esc($data['postalcode']),
                        'country'  => esc($data['country']),
                        'text'   => esc($data['text']),
                        'sender' => esc($data['company']),
                        'when' => esc($data['when']),
                        'howlong' => esc($data['howlong']),
                        'source' => esc($data['source']),
                        'target' => esc($data['target'])
                    ],
                    'attachments' => $attachments
                ]);
