Plunk

Plunk is a complete email platform that helps you send three main types of emails from one place. First, there are transactional emails - the automatic messages your app sends like password resets or order confirmations. Second, marketing automations - email sequences that trigger based on what your users do. Third, broadcast campaigns - newsletters and updates you send to many people at once.

The platform is open-source, which means the code is public and you can even host it yourself if you want. It runs on Amazon's email service, which makes it reliable and fast. Plunk offers a clean dashboard where you can create emails, track who opens them, and manage your contact list all in one spot.

Getting started with Plunk is straightforward. Here's how to use it effectively:

• Sign up and set up your account at useplunk.com. You can start with the free plan which includes 3,000 emails per month across all types.

• Verify your domain so emails come from your own address instead of Plunk's. This step is important for email delivery and trust.

• Create your first email using the built-in editor. You can design responsive emails visually or import your own HTML code if you prefer.

• Set up automations by choosing triggers like when someone signs up or takes a specific action. The platform will automatically send the right email at the right time.

• Use the API to send transactional emails directly from your application code. Plunk provides simple API documentation and libraries for popular programming languages.

• Track results through the dashboard to see open rates, click rates, and other important numbers.
