At LogicalStreet, we’ve spent months in the trenches with coding agents. And let’s be honest, this isn’t a fairy-tale of automation and magic. It’s closer to hiring a hundred interns who never sleep, never stop typing, and never really understand what you meant unless you spell it out. We didn’t start out with a grand philosophy. We […]

Introduction Scaling email with n8n is easy. Scaling safely—without burning your domain or annoying busy recipients—is the real craft. Deliverability is a mix of protocol hygiene (SPF/DKIM/DMARC), sending patterns (warm‑up, pacing, consistency), message quality (HTML, links, preview lines), and respect (unsubscribe and suppression policies across campaigns). Compliance adds another layer: know what you’re allowed to send, keep the […]

Introduction Outreach that you can’t measure is outreach you can’t improve. Teams often get a sending workflow running in n8n and stop there—emails go out, replies trickle in, and the source of truth becomes a messy spreadsheet plus a few Slack threads. The result? Duplicate sends, unreliable metrics, and a long detective story every time […]

Introduction Open rates are noisy; conversations drive business. If your outbound process can send but not listen, you’ll miss genuine buying signals, annoy busy recipients with off‑timing follow‑ups, and lose track of which threads are worth your time. This guide shows how to transform a one‑way sender into a reply‑aware outreach system using n8n, Gmail/IMAP, […]

Introduction Teams often maintain contact lists in Google Sheets, draft emails manually, and toggle between tabs to get one small campaign out of the door. It’s slow, prone to copy‑paste errors, and hard to measure. The workflow described here replaces the manual steps with a transparent, auditable pipeline in n8n. It reads contacts from a spreadsheet, […]

By the end of this guide, you will: This post is perfect for: Anyone tired of fighting with localhost redirects! Why “localhost” Breaks Google OAuth in n8n When n8n generates an OAuth request, it includes a callback URL. By default, if not configured, it uses: So, after a user authenticates via Google, it tries to […]

Why Agents, Why Now? Chatbots used to be the darlings of automation. They were easy to implement and gave users a taste of conversational AI. But when you needed more than canned responses—like resolving complex support issues or making context-aware decisions—chatbots fell short. Enter LLM agents. With the rise of powerful models like GPT-4o, we […]

In a world full of service providers, only a few stand out as trusted partners.The reason? They don’t just do what’s asked — they think, contribute, and elevate outcomes. This is the shift from being a task-doer to a thinking partner — and it’s a game-changer for client relationships, long-term growth, and brand credibility. Whether […]

APIs (Application Programming Interfaces) are the backbone of modern software systems. Whether you are developing an e-commerce platform or a mobile application, API design is important in enabling seamless communication between various systems. Good API design ensures that developers can easily integrate your system, allows for scalability, and ensures users have the best possible experience. […]
