Basecamp vs Google Groups

Basecamp tackles project management with a focus on communication and collaboration. Making to-do lists and adding to-do items literally just takes seconds. Basecamp is optimized to make the things you do most often really fast and really easy. Basecamp mobile is especially made for popular mobile devices like iPhone and Android. Basecamp free alternatives are Trello and Asana. If you are looking for open-source self-hosted Basecamp alternatives pay attention to RedMine or ProjectPier.
Google Groups
Google Groups provides a convenient way for your users to send messages to groups of people they frequently contact. A group contains the email addresses of its members, so users can send a message to all the group's members using the single address for the group.
