Building a Custom Brevo Integration Plugin for WordPress – A Codeboxr Case Study
At Codeboxr, we specialize in building custom WordPress plugins that integrate deeply with third-party platforms. This case study explains how we built a fully custom strong>Brevo integration for WordPress that allows email campaigns to be created, scheduled, synced, and managed directly from the WordPress dashboard.

Project Background
Content teams often manage newsletters in WordPress, while email campaigns live inside external tools like Brevo. This split workflow creates friction, duplicated effort,
and limits automation opportunities.
The goal of this project was to build a custom WordPress plugin for Brevo that brings campaign management closer to content creation.
The Core Problem
The existing workflow required users to manually move data between systems:
- Write and manage posts in WordPress
- Design templates separately in Brevo
- Rebuild campaign content for every send
- Manually schedule or update campaigns
This approach was time-consuming and limited the ability to send dynamic, content-driven newsletters.
The Solution: A Custom Brevo Integration
Codeboxr developed a standalone WordPress plugin that integrates directly with the Brevo API and introduces a campaign-first workflow inside WordPress.
The plugin allows users to:
- Create Brevo campaigns from the WordPress admin panel
- Store campaigns locally in WordPress
- Save campaigns as drafts or schedule them live in Brevo
- Sync campaigns between Brevo and WordPress
Dynamic Email Templates with Real Content
A key requirement was support for fully custom HTML templates created inside Brevo.
Instead of generating email markup inside WordPress, the plugin allows users to select an existing Brevo template from a dropdown in the campaign creation form.
Dynamic Post Data Injection
The plugin sends structured WordPress data to Brevo for dynamic rendering. This includes:
- Post title
- Featured image
- Post URL
- Post content or excerpt
Brevo templates use this data to automatically render newsletters such as “latest posts”, product updates, or curated content emails.
This removes manual copy-paste work and ensures campaigns always reflect the most up-to-date content.
Campaign Creation Inside WordPress
The campaign creation screen provides a clean, familiar experience:
- Select newsletter template from Brevo
- Set subject line and sender details
- Choose recipient lists
- Select schedule date and time using a date picker
Local Storage and Campaign States
Every campaign can be stored locally in WordPress. This enables:
- Draft campaigns without API calls
- Editing before syncing with Brevo
- Historical tracking of campaigns
Campaigns can exist as:
- Local draft
- Brevo draft
- Scheduled live campaign
Two-Way Campaign Synchronization
The plugin supports bi-directional syncing:
- Import existing Brevo campaigns into WordPress
- Update Brevo campaigns from WordPress changes
- Maintain consistency across both systems
Plugin Global Seting
The plugin has global WordPress native settings for storing api key and other fields
Technical Highlights
- Secure Brevo API integration
- Scalable campaign data model
- Custom admin UI built for marketers
- Future-ready architecture for automation
Results and Impact
This custom Brevo integration delivered clear benefits:
- Campaigns managed without leaving WordPress
- Faster newsletter creation
- Dynamic, content-driven emails
- Reduced manual effort and errors
Why Custom Integrations Matter
Generic plugins solve generic problems.Custom integrations solve real workflows.
This project demonstrates how a tailored WordPress Brevo integration can unlock automation that off-the-shelf tools cannot.
Conclusion
This case study reflects Codeboxr’s approach: building clean, scalable, and business-focused custom WordPress solutions.
When content, email, and automation work together, marketing becomes simpler — and more powerful.
