I did some research to see what mailing list options WordPress offers. Below is a list of WordPress mailing list plugins that don't require help and that do require help from outside services. When I say 'outside service', I'm talking about email list services like MailChimp, etc. solely dedicated to offering email list services.
WordPress mailing list plugins that don't require an email list service
- mail list
- benchmark email lite - This WordPress email mailing list plugin is very interesting, it allows you to very easily send subscribers an email version of a particular blog post. I like this idea, because you don't ever have to conpose email newsletter, just send your blog posts.
- commenter emails - This plugin allows you to extract a CSV formatted list of all the commenters of your WordPress blog. This CSV is ment for adding to an email list program via the import CSV file functions. Most email list programs have this capability. Beware, it's not really legal to add people to your email list without their permission and many hosting companies will investigate this type of activity and ban your account.
- email newsletter - This plugin allows you to send html emails to registered users and 'commenters' of your WordPress website.
- speakup! email petition - This plugin allows you to create an email petition on your WordPress website. When people fill out the form, a copy of your petition letter is sent to an email address you specify with the subscriber's signature.
