Why this works
n8n fires a weekly research job that sends topic prompts to Perplexity, which returns cited summaries of recent signal events. Gumloop's multi-agent pipeline transforms research outputs into structured newsletter sections and scores multiple subject line variants. The draft lands in Taskade's editorial checklist for human review and final send approval.

FAQ
Which email platforms does n8n support for the send trigger?
n8n has native integrations for Beehiiv, ConvertKit, Mailchimp, Substack API, and any platform with a REST API. You configure the send trigger to post the final draft to your platform's scheduling endpoint.
How does Perplexity ensure research is recent and not outdated?
Perplexity's Pro search uses real-time web access with date filters. You can configure n8n to pass a date range parameter (e.g., past 7 days) with each research query to ensure only recent content is returned.
Can the subject line scoring be A/B tested automatically?
Gumloop scores variants based on learned patterns. For actual A/B sends, you need your email platform's split-test feature. Beehiiv and Mailchimp have native A/B subject line testing you can trigger via API from n8n.
