Improved conversation grouping methods and systems are provided for electronic mail records. Electronic mail messages that are unread or flagged for follow-up are automatically displayed under an associated conversation grouping heading. If a conversation grouping contains only a single unread or flagged electronic mail message, the single electronic mail message is automatically displayed under the conversation grouping heading for review by a user. For a conversation grouping having no unread or flagged electronic mail messages, the latest electronic mail message in the grouping is automatically displayed under the conversation grouping heading.
