quick question about my game development: Users will input their login info, and then the game app sends an email verification. Is it safe to use my personal email for this?

const sendMail = async (email, mailSubject, content) => {
    try {
        const transport = nodemailer.createTransport({
            service: 'gmail',
            host: 'smtp.gmail.com',
            auth: {
                user: process.env.SMTP_MAIL,
                pass: process.env.SMTP_PASSWORD,
            },

        });

        const mailOptions = {
            from: process.env.SMTP_MAIL,
            to: email,
            subject: mailSubject,
            html: content
        }
        transport.sendMail(mailOptions, function (error, info) {
            if (error) {
                console.log(error)
            } else {
                console.log('Mail sent successfully:-'.info.response);
            }
        });
    } catch (err) {
        console.log(err.message);
    }
}
