Building a Self-Hosted Email Marketing Infrastructure with MailWizz & Postal
Overview
Quad Nathan needed a reliable, self-hosted email marketing system that would give them full control over their email campaigns, mailing lists, and sending infrastructure while reducing dependence on third-party email platforms.
About the Client
Quad Nathan is a business seeking a scalable and cost-effective email marketing solution capable of managing campaigns, subscriber lists, and high-volume email delivery through its own infrastructure.
Goal
The objective was to deploy a secure and fully functional email marketing ecosystem using MailWizz and Postal, ensuring the platform was properly configured for campaign management, email authentication, and dependable email delivery.
Challenges
The project involved configuring multiple server components, integrating MailWizz with Postal, securing the server with SSL, and implementing proper DNS authentication (SPF, DKIM, and DMARC). Careful tuning was also required to ensure stability, performance, and reliable email delivery.
Solution & Outcome
A complete email infrastructure was successfully deployed on a Linux VPS. Postal was configured as the SMTP server, while MailWizz was installed and connected for campaign management. SSL certificates were implemented to secure the platform, DNS authentication records were configured, and the entire environment was tested to confirm successful email transmission. The client received a production-ready system capable of managing email campaigns independently.
Knowledge Gained
This project strengthened my expertise in Linux server administration, MailWizz deployment, Postal configuration, Docker-based services, DNS management, email authentication protocols, and end-to-end email infrastructure deployment.
Business Impact
With a self-hosted email marketing platform, Quad Nathan gained greater control over email operations, reduced recurring software costs, improved scalability, and established a foundation for reliable and secure email marketing as the business grows.

Sendy Email Infrastructure Deployment
A manufacturing business needed a reliable, self-hosted email marketing platform to manage its growing contact database and send newsletters at scale. They wanted full control over their email operations while maintaining strong inbox placement.
The project involved deploying Sendy on an Ubuntu VPS, integrating Amazon SES and Postmark, configuring Apache, PHP-FPM, MariaDB, SSL, and DNS authentication (SPF, DKIM, and DMARC), resolving installation and server configuration issues, verifying the mailing list, warming up the sending reputation, and optimizing deliverability before launching campaigns.
Through this project, I strengthened my expertise in Linux server administration, email authentication, SMTP integrations, deliverability optimization, and large-scale email deployment.
The outcome was a stable, secure, and scalable email marketing system that gave the client greater control over email campaigns, improved deliverability, and reduced long-term sending costs.
