What if your email strategy worked perfectly…until it crossed a border?

What if your email strategy worked perfectly…until it crossed a border?

In this episode of Email After Hours, Guy Hanson and Danielle Gallant sit down with global email expert Alexandre “Alex” Coussy. They unpack the realities of email marketing across borders, with a deep dive into Australia’s unique ecosystem.

From regional mailbox providers like BigPond and Optus to Microsoft dominating the market share outside the US, the conversation reveals why deliverability strategies that work in North America or Europe can quickly fall apart in other regions. Alex shares practical insights from his international experience across France, New Zealand, Hong Kong, and Australia, highlighting the importance of localization, technical precision, and adhering to privacy laws.

Whether you’re scaling into new markets or optimizing an existing program, this episode offers a clear roadmap to staying compliant, relevant, and effective—no matter where your audience is.

What you’ll learn:

• Why Australia’s mailbox providers (like BigPond and Optus) require a different deliverability approach
• What makes Australian consent laws stricter and how they differ from US regulations
• How to diagnose and recover from regional bounce spikes with a structured approach
• Why localization (seasonality, tone, and culture) directly impacts engagement and performance
• How to use AI as a practical workflow tool, not just a trend, for email marketing

…and more!
