Mailboxer is a Ruby on Rails gem that adds a private messaging system to web applications. It supports multi-participant conversations, system notifications, email delivery, and per-user mailboxes with inbox, sentbox, and trash folders.

Use cases

• add private messaging between users in a Rails app
• implement group conversations with multiple participants
• send in-app system notifications to users
• notify users by email when they receive a message
• give each user an inbox, sentbox, and trash mailbox

When to choose

• you need a ready-made messaging layer for a Rails application
• you want conversations, notifications, and email delivery in one gem
• you need per-user mailboxes without building the schema yourself

When to avoid

• you are not using Ruby on Rails or ActiveRecord
• you need real-time chat with websockets rather than stored messages
• you need a heavily customized messaging model beyond conversations and notifications
