Way of sending mails

[10NANCY]

I have an ecommerce site and want to send out new letters very frequently through scripts. Has anyone used SMPT authentication for mail scripts? Is it a secure way of sending mails ?

I think you are talking about SMTP Authentication. Yes, SMTP Authentication is secured enough and is reliable. Therefore, you can use it. However, you need to make sure that you have done the settings and configuration of it properly.
