pass: config.SMTP_SECRET
},

const transporter = nodemailer.createTransport(credentials);

const mailOptions: any = {
from: config.SMTP_EMAIL,
to: receiverEmail,
subject,
headers: {
"X-Laziness-level": 1000,
"charset": 'UTF-8'
},

transporter.sendMail(mailOptions, (error, info) => {
if (error) {
console.log(error.message)
reject(false)
} else {
resolve(true)
}
});
