BrainStudioz Newsletter Hub

BrainStudioz Newsletter Hub is a WordPress newsletter plugin for building email signup forms, keeping a local subscriber database, and syncing contacts with popular email marketing services.

Your forms and subscriber records stay in WordPress as the source of truth. Connect Mailchimp, Brevo, MailerLite, Kit (formerly ConvertKit), ActiveCampaign, or another supported provider when you want to sync contacts. Add or switch providers without rebuilding your signup forms.

BrainStudioz Newsletter Hub manages subscribers and provider syncs; it does not send newsletter campaigns itself.

Newsletter forms and subscriber management

• Build newsletter signup forms with a drag-and-drop form builder
• Add forms with the Newsletter Form block, shortcode, Elementor widget, or PHP function
• Use inline, floating-bar, and slide-in form displays
• Store, search, filter, tag, import, and export subscribers in WordPress
• Record consent and suppress unsubscribed, bounced, or blocked contacts
• View subscriber growth, form views, submissions, and conversion rate

Email marketing integrations

Connect Mailchimp, Brevo, MailerLite, Kit (formerly ConvertKit), ActiveCampaign, GetResponse, AWeber, Campaign Monitor, Drip, or Constant Contact.

Choose lists or groups, map custom fields, apply tags, and configure double opt-in per connection. You can connect several providers or multiple accounts from the same provider.

Capture subscribers from existing WordPress forms

Turn submissions into newsletter subscribers from WordPress comments and registration, Contact Form 7, WPForms, Gravity Forms, Ninja Forms, Fluent Forms, Formidable Forms, Elementor Forms, or JetFormBuilder.

How subscriber sync works

1. A visitor submits a newsletter or connected WordPress form.
2. BrainStudioz Newsletter Hub stores the subscriber in your WordPress database.
3. The plugin queues a background sync for your connected provider.
4. Automatic retries handle temporary API errors and rate limits.

Privacy by design

Subscriber data is stored on your WordPress site. The plugin collects no telemetry, sends no usage analytics, and makes no provider request until you configure a connection with your own credentials. Provider credentials are encrypted at rest. See External Services for exactly what is shared when sync is enabled.

Optional Pro add-on

The separate optional Pro add-on adds audience routing, WooCommerce order tracking, popups, lead magnets, automations, webhooks, AI tools, and provider migration. The free plugin works independently.

External Services

BrainStudioz Newsletter Hub contacts no external service by default. After you add a provider connection with your own credentials, a sync sends the subscriber data you collected to that provider’s API. This may include email address, name, mapped custom fields, tags, and list membership. No data is sent to the plugin author.
