Subject: Ruby Courses in Your Inbox

I am launching a new project: Ruby Courses over email.

Text is still an incredible medium for learning, and email remains one of the most straightforward forms of online communication.

You may find yourself flooded with emails every day. Or maybe you keep your Inbox clean.
No matter the case, here is my proposal for you:

What if your email can be the place to learn something new?
Like discovering technical insights or helping you stay updated with what’s new in Ruby or Rails?

I aim to respect your preferences and send you a clear, text-focused email, perhaps with code snippets or images that will bring you a new perspective or know-how about a specific topic.

I think there is something beautiful about receiving a well-crafted, concise email that offers valuable knowledge.

The inbox isn't just a repository for tasks, chores, and to-do’s; it can also be a source of discovery and inspiration.
