What this is
n8n is a workflow automation tool. By calling the Twain API from an n8n workflow, you can trigger Twain's research and writing automatically off any event, a new signup, a booked demo, an inbound signal, or a cold lead going quiet, and have the result land where your team already works. Twain does the research and the first draft in seconds; a human still reviews and sends. These guides give you a ready-made template for each common use case.
What you can automate
Auto-qualify signups, score each new signup against your ICP and route only real fits to Slack and HubSpot.
Send a researched welcome, draft a personalized welcome for every signup, ready in Gmail for your approval.
Prep reps for demos, build an AE brief and a pre-demo email the moment a meeting is booked.
Personalize LinkedIn outreach, turn a signal into a researched LinkedIn intro plus follow-ups, drafted for you to send.
Re-engage cold leads, read each cold lead's prior conversation and draft a re-engagement that continues the thread.
What they share
All of these work the same way underneath, so once you have built one the rest are familiar:
You stay the sender. Every workflow stops at a draft. Nothing is sent automatically, a person reviews and sends.
The quality comes from your Twain campaign. You set up a campaign and Agent once, in plain language, and every run inherits it. Tighten the campaign and the output tightens with it.
They handle personal emails. When a lead only has a personal inbox, an optional LinkedIn lookup can resolve their profile so Twain still has something to research. If there is nothing usable, the lead is skipped with a note in Slack, never silently dropped.
Each ships as an importable template. The full n8n template lives on the linked blog post for each use case. You import it, add your own connections, and paste in your campaign.
What you need
An n8n instance
Your Twain API key, added in n8n as a Header Auth credential (see API access)
A Twain campaign set up for the job you want to automate
Connections for wherever the result should land (Slack, Gmail, HubSpot, HeyReach), depending on the workflow
How this differs from Twain Workflows
This is not the same as the built-in Workflows feature inside Twain (which runs Import, Campaign, Export, and Notification steps inside the app). These setups call the Twain API directly from n8n workflows you build and host yourself, so they run outside the app and can react to any trigger n8n supports.
