What it does
Many site owners collect subscribers in WordPress and then move to a separate service to write and send their newsletters. This plugin keeps that work inside WordPress. You build emails with a drag-and-drop editor and customizable templates, so you can match your brand without writing code. Newsletters use a responsive design, which means they adapt to desktop and phone screens. Campaigns can be written in multiple languages if your audience spans more than one region.
Subscriber management sits in a dashboard with segmentation options, letting you target people by behavior and preferences. Autoresponders and automated campaigns handle follow-up emails for you. The plugin connects with WooCommerce, Contact Form 7 and Gravity Forms to bring in subscribers automatically, and it includes built-in SMTP support for sending. Reports track opens, clicks, bounces and unsubscribes, and GDPR consent tools help keep your list in line with privacy rules.
Best for
- Bloggers who want to email posts and updates to readers
