The Newsletter Signup Modal plugin adds a clean, modern, and fully customizable subscription popup to your WordPress website. Designed with a minimalist approach (no icons, just elegant typography and shapes), it helps you grow your email list without distracting your visitors.
Built for simplicity and performance, the modal appears automatically after 2 seconds (you can adjust the delay) and can be closed by clicking outside, pressing ESC, or using the “No thanks” link. The subscription form includes name (optional), email, and a GDPR‑friendly consent checkbox.
Key benefits for your site:

• Increase newsletter subscribers with a non‑intrusive, beautiful popup.
• Seamless integration with Kit (formerly ConvertKit) V4 API – no third‑party scripts.
• Lightweight and fast – only ~10KB of CSS/JS, no external libraries.
• Fully responsive – looks perfect on desktop, tablet, and mobile.
• No icons used anywhere, keeping the design clean and brand‑agnostic.

How it works:
When a visitor lands on your site, the modal fades in after 2 seconds. They enter their name and email, accept the privacy consent, and click “Subscribe”. The plugin securely sends the data to your Kit account (V4 API) and displays a “Thank you for subscribing to the Newsletter” message in a separate confirmation window. All without reloading the page.
Admin settings:
Go to Settings → Newsletter Modal and paste your Kit V4 API key. That’s it! No complicated configuration.
