A manufacturing business needed a dependable email delivery solution to launch outreach campaigns while building a strong sender reputation. The priority was reliable inbox placement before transitioning to a larger-scale sending infrastructure.

The goal was to integrate Postmark with the client's email marketing platform and establish a stable, compliant sending environment for gradual email warm-up.

The challenge was configuring the integration correctly, authenticating the sending domain with SPF and DKIM, monitoring delivery performance, and executing a controlled warm-up strategy to protect the domain's reputation.

After configuring Postmark and optimizing the sending setup, the client successfully launched campaigns with consistent delivery while closely monitoring opens, bounces, and unsubscribes to guide future optimization.

This project expanded my expertise in transactional email services, sender reputation management, email authentication, and deliverability optimization.

The result was a reliable email delivery system that improved inbox placement, supported a healthy sender reputation, and provided the client with a solid foundation for scaling future email campaigns.
