node js Set Interval方法调用

发送邮件() 功能。因此,电子邮件只发送到最后一个电子邮件id。下面你可以看到我的代码,请有人能帮我解决这个问题吗

async function mailSend(callback) {

    for (let scriptData of automatedScriptData.dataList) {
        var userData = {
            email: scriptData["Business Email"],
            password: "acc0unt@123",
            name: scriptData["First Name"] + " " + scriptData["Last Name"],
            firstName:scriptData["First Name"],
            title: scriptData["Title"],
            timeZone: scriptData["Time Zone"],
            location: scriptData["Country"],
            company: scriptData["Company"]
        };

       setInterval(function() {
         console.log(userData.email);
           sendtheMail(userData);
           }, 5*1000); 

    }

}
