How to Build a Custom WordPress Block for a Newsletter Signup Form (Step-by-Step Tutorial)

Want to create a fully custom WordPress block for a newsletter signup form? In this in-depth tutorial, you’ll learn how to build a dynamic, PHP-rendered block inside your own WordPress theme — without relying on plugins!

We’ll walk through:
• Setting up the block folder structure (block.js, render.php, block.json)
• Registering the block in functions.php
• Writing custom React-based block editor code
• Styling the block with both frontend and editor-specific CSS
• Handling form submissions using admin-post.php
• Comparing shortcode vs. block development methods

By the end, you’ll have a fully functional, reusable block you can add anywhere in your site — including footers, pages, and templates.

🔧 Tools Used: Local WP, Mailpit, WordPress Block Editor
