This email also includes an unsubscribe link.\n* The unsubscribe flow works similarly via n8n form interface which when submitted disables further scheduled emails to the user.\n\n## How to use\n* Make a copy of sample Airtable here: https://airtable.com/appL3dptT6ZTSzY9v/shrLukHafy5bwDRfD\n* Make sure the workflow is \"activated\" and the forms are available and reachable by your audience.\n\n\n### Need Help?\nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!\n\nHappy Hacking!"
