Great self-hosted solution with awesome support

If you already have a WordPress website and want to start email marketing, this should be your first choice as the subscriber data, campaigns and sending is all managed inside your own WordPress installation. With another plugin you can even use your already existing email account’s SMTP access to send the emails making your email newsletter completely free to operate.

The subscription tiers provide detailed statistics and quick support if something goes wrong, so I did subscribe to Max and I am very satesfied with the service.
