Moving from Python Automation to n8n - Looking for Practical Delivery Tips

Hi @everyone Ahmad here.

I come from a Python scraping background (I already deliver those solutions) and I’m now learning n8n. I’m building lead-gen + outreach flows and small agent-style automations to win new clients and I’d love practical advice from people who’ve shipped this commercially.

A few specific things I’m curious about:

do you build directly in the client’s n8n instance or export JSON and hand it over? Pros/cons you’ve found.
Common pitfalls when scaling outreach automations (personalization at scale, bounce handling, throttling, etc.).
Must-have nodes/plugins, hosting tips, or debugging tricks that saved you time.
Simple checklist for client-ready n8n projects (what to include: env vars, docs, tests, runbooks, etc.).

If you’ve got one short tip, a template, or a link, please drop it. I’ll share a basic flow in return for helpful replies. Thanks!
