Original: Clean quoted replies from email with the Nylas API
Short summary
This tutorial demonstrates how to use the Nylas API and CLI to strip quoted replies, signatures, and disclaimers from email threads, leaving only the meaningful new text. It covers two paths: an on-demand PUT endpoint for cleaning specific messages (up to 20 per call) and a message.created.cleaned webhook for automatic cleaning of incoming mail. The operation is non-destructive, returning a parsed copy while preserving the original message, making it safe for pipelines that feed cleaned text to language models.
- •On-demand endpoint cleans up to 20 messages per call, returning stripped conversation text
- •Webhook path automatically cleans every incoming message for pipeline use
- •Non-destructive operation preserves original message for safe reprocessing
