ThemeSync Subscribe is a themed email subscription plugin for WordPress. It ships with 5 pre-designed themes (Minimal, Editorial, Boutique, Studio, Noir) that style every piece of the subscription experience — the slide-in popup, inline shortcode form, sidebar widget, confirmation email, post-notification email, and broadcasts — from one click, so the look stays consistent end to end.

You can also set an optional accent color (hex) to match your brand without touching CSS, and the plugin automatically picks accessible text contrast for buttons.
