CiviMail
CiviCRM’s bulk email feature has all the functionality of commercial mailing apps like MailChimp and Constant Contact. You are provided with a basic, mobile-friendly mailing template that can be customized with your colors and logo.
Feel free to play with CiviMail, but note that there is no mail processor enabled for this test site so no mail will be sent. You can still explore features like editing headers, footers and templates, including/excluding Groups as Recipients, etc.

Reports include all the typical mailing stats: Deliveries, Opens, Click-throughs, Bounces, etc.
