Overview

Newsletter Glue is a WordPress newsletter plugin launched in 2016, headquartered in the United States, that lets creators and businesses create, publish, and track newsletters in the familiar WordPress editor without switching tools. Newsletter Glue does not handle email delivery itself; instead it integrates 5+ email service providers — Mailchimp, ConvertKit, Mailerlite, Kit, and more — as delivery backends, combining WordPress content creation with professional ESP delivery.

Newsletter Glue's core value is completing the full newsletter workflow inside WordPress: creators write emails in the WP editor (Gutenberg or classic), use Smart Paste to convert published blog posts into newsletters with one click, set up subscription forms and membership content, and pull back open and click statistics after sending. The entire flow stays inside WordPress, reducing content production overhead.

For bloggers, media sites, and creators already using WordPress, Newsletter Glue offers a lightweight, controllable email communication solution — teams maintain a single content source that produces both blog posts and newsletters. Within the email marketing platform ecosystem, it best fits teams already deeply invested in WordPress that want to minimize tool switching.

Key Strengths

  • Native WordPress Experience: Create newsletters in the familiar WP editor without learning a new editor or copy-pasting layouts, giving content teams a 0-migration path to email newsletters.

  • Smart Paste One-Click Conversion: Converts published blog posts into newsletter layouts automatically, saving 50%+ of email creation time — teams maintain just one content source.

  • 5+ Email Service Integrations: Supports Mailchimp, ConvertKit, Mailerlite, Kit, ActiveCampaign, and other major ESPs as delivery backends, keeping professional delivery while unifying content creation.

  • Subscription Forms & Membership Content: Built-in subscription form builder and 2 types of paid membership content, integrating seamlessly with the WordPress ecosystem — see membership site platforms for monetization.

  • Statistics Pull-Back: Automatically retrieves and displays 3 metrics (open rates, click rates, unsubscribe rates) in the WP admin, letting creators review email performance without switching to the ESP, and improving results with email deliverability optimization.

Product Ecosystem

WordPress Editor Integration

Newsletter Glue deeply integrates with Gutenberg and the classic editor, providing email-specific blocks and components for layout, images, buttons, and email previews — the creation experience matches writing a blog post.

Smart Paste

One-click conversion of blog posts into newsletter layouts, automatically extracting titles, summaries, images, and body text with manual fine-tuning afterward — a core efficiency tool for content reuse and multi-channel distribution.

Subscription Forms & Landing Pages

Built-in subscription form components embed in posts, sidebars, and custom pages, with landing page building to collect subscribers and sync them to the connected ESP — follow subscriber management best practices.

Automation & Membership

Supports automated emails (welcome sequences, content update notifications) and paid membership content distribution, connecting WordPress membership plugins with email newsletters for a sustainable subscription business model.

Delivery & Statistics

Delivery runs through the connected ESP, with open, click, and unsubscribe rates pulled back to the WP admin, plus email archiving and resending; configure SPF/DKIM/DMARC on your sending domain to protect deliverability.

Limitations

  • WordPress Ecosystem Dependency: Newsletter Glue is a WordPress plugin, so teams not on WordPress cannot use it without migrating or abandoning the approach.

  • Delivery Depends on Third-Party ESPs: The plugin does not handle delivery, so you must purchase a separate Mailchimp, ConvertKit, or other ESP service — email cost equals plugin plus ESP, which small teams should budget carefully.

  • Advanced Features Need Paid Version: Smart Paste, membership, and automation require the paid version; the free tier is fairly basic.

  • Creator-Focused Positioning: Better suited to individual creators and small teams for content newsletters; large enterprises' complex marketing automation still needs full platforms like Mailchimp or HubSpot.

Use Cases

  • Blog/Media Content Newsletters (★★★★★): Automatically reuse blog content as newsletters with one content source and multi-channel distribution — ideal for WordPress bloggers.

  • Creators & Personal Brands (★★★★★): Independent creators build direct subscriber relationships through subscription forms and membership content for a sustainable content business.

  • SaaS & Product Teams (★★★★): Send product updates, tutorials, and onboarding via email automation, boosting activation and retention with email automation.

  • Ecommerce & Brand Marketing (★★★): Send promotions and cart reminders alongside WooCommerce, though dedicated email marketing platforms may fit complex ecommerce marketing better.

  • Internal Newsletters & News (★★★): Low-cost recurring delivery of internal communications and industry news built on the WordPress content system.

Pricing note: Newsletter Glue uses annual subscriptions, and delivery requires a separately purchased connected ESP service, so total cost equals plugin subscription plus ESP fees.
