Post Editing And Modification

via “post-editing-and-modification”

via “message-editing-and-deletion-with-history”

Unique: Applies unified edit/delete logic to both email and chat messages, allowing users to edit email messages after sending (which traditional email doesn't support). This requires server-side message storage and rendering, not just SMTP forwarding.

vs others: More flexible than email (which doesn't support post-send editing) but less comprehensive than Slack's message editing (which shows edit history inline without requiring a separate view).
