Definition
Martech is the collection of software and technology solutions that support marketing activities. The term covers everything from email service providers (ESPs) and customer relationship management (CRM) platforms to analytics tools, customer data platforms (CDPs), automation platforms, and AI-powered optimisation tools.
For email marketers specifically, the martech stack typically includes an ESP as the core platform, supplemented by tools for deliverability monitoring, email design and testing, list verification, analytics, and integration with CRM and e-commerce systems. The martech landscape has grown exponentially — there are now over 14,000 martech solutions globally, with email-related tools representing one of the largest categories.

Best Practices
- Build a martech stack that integrates seamlessly rather than collecting disconnected tools
- Prioritise platforms that offer open APIs and webhook support for custom integrations
- Audit your martech stack annually to eliminate unused or redundant tools
- Invest in training — the best tools underperform without skilled operators
- Consider total cost of ownership including integration, training, and migration costs

Frequently Asked Questions
Your email service provider is the most critical investment, as it handles deliverability, list management, automation, and analytics. All other tools should integrate with and complement your ESP. For most programmes, the second most important investment is a deliverability monitoring tool.
Map your stack to specific use cases and eliminate tools that overlap. If your ESP already offers built-in analytics, automation, and template building, you may not need separate tools for each function. Start with your core ESP and add specialised tools only when specific gaps emerge.
