Four Python Myths Debunked: Lessons Learned Building a Python Email API

In less than two years, Nylas developed a Python-based email API that is trusted by thousands of developers globally, illustrating Python's strength as an enterprise-level programming language despite common misconceptions about its scalability, speed, and reliability. Python's perceived limitations are countered by its extensive ecosystem of libraries and its adaptability to various applications, as evidenced by its use in major companies like YouTube and Instagram. Nylas chose Python for its simplicity, diversity of libraries, and ability to efficiently manage server operations, which allowed them to build a robust, scalable, and reliable tech stack that processes billions of email, calendar, and contact events weekly. By leveraging Python's open-source modules and frameworks, such as Gevent, Flask, and SQLAlchemy, Nylas created a cloud-core engine that powers their RESTful API, enabling seamless integration of messaging services in applications. The language's strong community values, including diversity and openness, align with Nylas's ethos, making Python a strategic choice for their architecture, which focuses on delivering high uptime and stability without reinventing the wheel.
