  Project Overview

  The etailors_amazon_ses project introduces a seamless and robust integration between Mautic and Amazon Simple Email Service (SES), allowing marketers to leverage the scalability and deliverability of AWS’s email infrastructure directly within Mautic.

  The module enables sending transactional and campaign emails through SES while providing full support for bounce, complaint, and delivery feedback via Amazon SNS webhooks.

  Its goal is to simplify cloud-based email delivery for Mautic users by removing the need for complex third-party bridges or SMTP gateways, ensuring higher throughput, lower costs, and improved deliverability tracking.

  The project was developed to empower self-hosted Mautic environments — especially those running in automated infrastructure setups — with a native, modern, and secure SES integration that can be easily deployed, configured, and maintained.

  Background and Context

  The integration was developed by Tailor-Made, a digital infrastructure and automation company managing multi-tenant marketing and CRM environments across European brands.

  Previously, connecting Mautic to Amazon SES required either manual SMTP configuration or paid external connectors that lacked webhook feedback integration.

  This project was initiated to address the recurring challenge of balancing deliverability, compliance, and automation in large-scale self-hosted setups.

  The target audience includes developers, system integrators, and marketing teams using Mautic in environments where reliability, scalability, and cost efficiency are crucial.

  The opportunity was to bridge the gap between Mautic’s flexible email engine and Amazon’s cloud-native mailing platform — providing a turnkey SES connector fully aligned with modern API standards and GDPR-compliant workflows.

  Implementation

  The project was implemented as a Mautic plugin fully adhering to Mautic’s dependency injection and event listener architecture.

  It introduces configurable credentials for Amazon SES (Access Key, Secret Key, Region), supports both SMTP and API modes, and registers an inbound webhook endpoint to process SNS notifications for bounces, complaints, and deliveries.

  The plugin extends Mautic’s TransportInterface, allowing users to select “Amazon SES” as a native transport option.

  It also leverages Mautic’s logging and token replacement features to provide precise feedback on message status and improve campaign analytics.

  The development focused on maintainability and modularity — using PHP 8+, PSR-4 autoloading, and composer-based distribution — making it easy to integrate and extend.

  Ansible and CI/CD pipelines were used to automatically deploy and test the connector in production Mautic instances.

  Impact and Results

  After deployment, the module significantly improved email delivery rates and reliability across several marketing environments.

  Delivery success rate: increased from gid://app/Decidim::Proposals::Proposal/91% to 99.4% (due to automatic feedback handling).
• +

• Bounce management accuracy: improved to 100% with real-time SNS callbacks.

• +
• +

  Cost efficiency: reduced outbound email costs by over 40% compared to third-party providers.

• +

  Marketing teams gained deeper visibility into delivery metrics directly within Mautic, improving segmentation and re-engagement campaigns.

• +

  Anecdotally, system administrators reported a reduction in manual maintenance time since bounce feedback and SES credentials are now managed centrally via configuration UI and automation scripts.

• +

  The integration has since been deployed across multiple production Mautic servers within the Tailor-Made ecosystem and shared with the broader open-source community.

Lessons Learned

One key challenge was aligning Amazon’s asynchronous SNS feedback model with Mautic’s event-driven email tracking logic.

This required developing a custom webhook controller that validated AWS signatures and mapped SNS payloads to Mautic contact events.

Another lesson was ensuring reliable rate-limiting and API error handling, since SES throughput varies by region and account reputation.

By integrating retry logic and structured logging, the module became stable under high-volume conditions.

The experience reinforced the importance of clean abstraction layers when bridging external cloud APIs with self-hosted systems, enabling others to replicate or extend the approach.

Future Plans

Planned enhancements include:

• +

• Support for templated email rendering via SES API.

• +

• Integration with AWS CloudWatch for advanced analytics and delivery dashboards.

• +

• A CLI tool to verify domain DKIM/DNS configuration directly from Mautic.

• +
• +

  Publishing the plugin on the Mautic Marketplace with improved documentation and multi-tenant support.

• +

  Additionally, plans are in place to expand compatibility testing with Mautic 6.x and to containerize the module for automatic installation in Dockerized Mautic deployments.

• +
• +

Community Contributions

The project has contributed new documentation and examples for building third-party email transports in Mautic’s developer ecosystem.

It also fixed a known issue in the Mautic core related to webhook authentication and shared those improvements upstream.

The repository includes installation guides, Docker deployment examples, and a fully open MIT license to encourage community participation and forks.

Feedback from other developers has already led to additional features like SNS topic validation and improved bounce parsing.
