Nylas API Costs

Costs of Microsoft Exchange API vs. the Nylas APIs

As your platform scales and your user base grows, so do costs for maintaining the Microsoft integration, such as:

  • Operating servers

  • Onboarding and training teams to specialize in EAS/EWS

  • Supporting the integration and troubleshooting bugs

  • Spending time specializing in EWS, EAS, and other protocols

  • Pursuing and maintaining compliance certifications

With Nylas, none of these costs apply — we manage servers, specialization, security certifications, and provide world-class support SLAs.
