As of version 0.7.0 (Aug 19, 2018) this gem is officially deprecated and will no longer be maintained. Please instead use Google's official Gmail API Ruby Client, which uses the Gmail API rather than IMAP and has significantly better performance and reliability. This gem is a Rubyesque interface to Google's Gmail via IMAP. Search, read and send multipart emails, archive, mark as read/unread, delete emails, and manage labels. It's based on Daniel Parker's ruby-gmail gem.
