I know I could program it myself, but maybe there is a simple (that's the keyword) package.
I like to add a box, snippet, form or page to my site for users to input their email address. Then I'd like it to automatically send email saying you have successfully subscribe. I'd want an unsubscribe link and I would be using SMTP on Google apps.
I would like to send email with HTML, so I can have a simple sentence with a complex link such as this.
I don't know if I'll get marked as spam if I try to send everyone an email at once. I'd like the software to manage it. Also, I'd like to get the emails in a simple format like CSV.
Is there a simple app that does this? if not i can write a simple form which does a simple insert (or delete when unsubscribing) and write a 200-300 line app to send my emails out for me.
