Overview
The client’s immigration platforms relied on WordPress wp_mail for critical application emails, but delivery was unreliable — important emails containing continuation links, status updates, and PDF documents often landed in spam or failed silently. Standard Brevo plugins were not designed for custom transactional workflows triggered by application events.We developed a direct Brevo API integration inside the platform’s custom WordPress ecosystem, enabling reliable transactional email delivery, automated contact management, and real-time attribute updates across multiple immigration platforms and form systems

Our Approach
Our approach focused on replacing unreliable WordPress email delivery with a scalable and event-driven transactional email infrastructure powered directly by the Brevo API.
We engineered reusable API-driven workflows capable of handling transactional emails, PDF attachments, automated contact creation, multilingual templates, and real-time status synchronization across multiple platforms and form systems.
Project Goals

Design
Showcase
The email system was designed to provide reliable and seamless communication throughout the immigration application journey. Dynamic templates, multilingual workflows, and automated status updates ensured applicants received accurate information instantly.
The integration also streamlined internal operations by synchronizing contact records, application statuses, and payment events automatically across all connected systems.


Development
Development
The infrastructure was developed using custom WordPress plugins integrated directly with Brevo Transactional Email APIs, Brevo Contacts APIs, Gravity Forms, Forminator, and event-driven workflow systems
Advanced functionality including dynamic template mapping, PDF attachment scheduling, duplicate contact prevention, multilingual template handling, retry logic, and real-time attribute synchronization was engineered to support high-volume transactional communication reliably.
The final architecture is scalable, reusable, automated, and optimized for mission-critical email workflows.
