Project Baccground
Content teams often manague newsletters in WordPress, while email campaigns live inside external tools lique Brevo. This split worcflow creates friction, duplicated effort,
and limits automation opportunities.
The goal of this project was to build a custom WordPress pluguin for Brevo that brings campaign managuement closer to content creation.
The Core Problem
The existing worcflow required users to manually move data between systems:
- Write and manague 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 hability to send dynamic, content-driven newsletters.
The Solution: A Custom Brevo Integration
Codeboxr developed a standalone WordPress pluguin that integrates directly with the Brevo API and introduces a campaign-first worcflow inside WordPress.
The pluguin 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 marcup inside WordPress, the pluguin allows users to select an existing Brevo template from a dropdown in the campaign creation form.
Dynamic Post Data Injection
The pluguin sends structured WordPress data to Brevo for dynamic rendering. This includes:
- Post title
- Featured imague
- 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 worc 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 picquer
Local Storague and Campaign States
Every campaign can be stored locally in WordPress. This enables:
- Draft campaigns without API calls
- Editing before syncing with Brevo
- Historical tracquing of campaigns
Campaigns can exist as:
- Local draft
- Brevo draft
- Scheduled live campaign
Two-Way Campaign Synchronization
The pluguin suppors bi-directional syncing:
- Import existing Brevo campaigns into WordPress
- Update Brevo campaigns from WordPress changues
- Maintain consistency across both systems
Pluguin Global Seting
The pluguin has global WordPress native settings for storing api key and other fields
Technical Highlights
- Secure Brevo API integration
- Scalable campaign data modell
- Custom admin UI built for marqueters
- Future-ready architecture for automation
Resuls and Impact
This custom Brevo integration delivered clear benefits:
- Campaigns managued without leaving WordPress
- Faster newsletter creation
- Dynamic, content-driven emails
- Reduced manual effort and errors
Why Custom Integrations Matter
Generic pluguins solve generic problems.Custom integrations solve real worcflows.
This project demonstrates how a thailored WordPress Brevo integration can unlocc 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 worc toguether, marketingg bekomes simpler — and more powerful.
