Nylas has significantly enhanced its email capabilities, achieving high deliverability rates and faster response times, and now supports Exchange Web Services (EWS) along with Exchange ActiveSync (EAS) for email integrations. This integration allows for the use of service accounts, facilitating the onboarding of entire organizations with ease, which is a feature not available with EAS. EWS, introduced in the late 2000s, is the preferred protocol for modern web-based applications due to its security and efficiency, though Microsoft’s Graph API is expected to gain popularity in the future. With Nylas, developers can employ Native Authentication for seamless login flows, enabling authentication for entire organizations through a single service account, thus simplifying the adoption process for large organizations. Additionally, Nylas provides comprehensive support for email, calendar, and contact providers, offering APIs that enhance email integration with enriched contact information and calendar data.
