EmailJS

Archie's take

EmailJS is a great fit for small teams, solo developers, or static site owners who need to send emails from client-side code without spinning up a backend. Its standout feature is the ability to connect directly to popular email services and send transactional or notification emails securely, all from the frontend—making it a real time-saver for rapid prototyping or simple web apps. However, it's not designed for high-volume, enterprise-grade email campaigns or complex workflows, and you’ll want to be mindful of client-side exposure and rate limits. The free tier is generous for light use, but costs can add up if your volume grows, so keep an eye on your usage as your app scales.
