Seeking Feedback: I built senderwolf to fix my Node.js email headaches. Is the API clean enough?

As a developer working on Audit Systems and internal tools, I’ve always found existing Node.js email libraries a bit... heavy. I wanted something that felt modern, was natively built with TypeScript, and could handle bulk sending without me manually managing connection pools. So, I built Senderwolf. It’s now at v3.5.0, and I’m at the point where I need "outsider" eyes to tell me where it breaks or how the DX (Developer Experience) could be better. What I’m trying to solve The goal was to create a library that is * 50-80% faster * for bulk emails by using built-in connection pooling and zero-config provider detection. The "Clean API" Test I’m really focused on the API design. Does this look intuitive to you? import { sendEmail } from "senderwolf"; await sendEmail({ smtp: { auth: { user: "your@outlook.com", pass: "password" }, // Auto-detects settings for 13+ providers }, mail: { to: "recipient@example.com", subject: "Weekly Report", html: ""<h1>Here is your data</h1>"", }, }); Specific
