当我连接到我的应用程序时，我会收到一封验证电子邮件，但是我的电子邮件地址已经过验证。我应该使用什么条件，以便在验证电子邮件地址时不发送验证电子邮件？非常感谢。这是代码：

public function verifyContactEmailAmazonSes() {

    $domainName = Str::after(request('domain'),'http://');
    $domainName = Str::after($domainName,'https://');

    $sesClient = new SESClient([
        'version' => '2010-12-01','region' => 'eu-west-1','credentials' => [
            'key' => config('aws.key'),'secret' => config('aws.secret'),],]);
    $sesClient->verifyEmailIdentity([
        'Emailaddress' => 'contact@'.$domainName,]);

    return response()->json([
        'status' => true,'message' => '',]);
}
