The best way is with the UltimateWB built-in mailing list app. Then you can also send out mailers to your mailing list. It is easy to use and integrate in your website. There are a lot of customization options, such as requiring them to confirm their email address, mail groups, and personalizing mailers to address subscribers by name.
