How to implement a simple newsletter/subscription system and mask recipients list

I need to create a simple e-newsletter or subsciption system in PHP. At first, I thought of using PHPList for WordPress but the plugin is compatible only up to 2.9.2, if I recall correctly.

• how can I mask my recipients list?
• what must I consider to not have mails considered as spam?
• how to send mail in batches?

I am open to use of plugins or 3rd party frameworks. I think they would provide valuabl开发者_如何学JAVAe insight to create such a system from scratch.

There are lots and lots of services that can provide newsletter services for you. You should seriously consider using one of them instead of rolling your own. Consider MailChimp, Exact Target and Constant Contact as popular options. All of them provide appropriate APIs.
