Hey Architects — need your input. My next client has a Carrd signup form for a push-up challenge. Goals: - Capture every signup into a simple database (leaning Google Sheets, maybe Airtable) - Send a weekly email every Sunday to everyone who signed up (reminder / motivation) Plan: Carrd form → n8n Webhook (POST) → store signup → weekly Sunday email from n8n to the whole list. Questions: - Any Carrd → webhook gotchas I should watch for? (duplicates, spam, timeouts, retries) - Would you build this as two workflows (intake + weekly sender) or one? - For Carrd: do I need admin access to paste the webhook URL, or is there another clean way? Appreciate any advice!
