PHPList Send 2 emails when i send the Campaña

hello, I am having a problem when sending the campaign, when sending the mail is received with the correct content but also another email simultaneously with the text [URLTEXT]. the main mail with the campaign shows me correctly but I want to delete the second one that sends I do not know where to find that option

@m1koscars Are you referring to sending a test email? If so, then add this to the config.php file and phplist will send only one test email

define('SEND_ONE_TESTMAIL', true);
