SendPost’s SendGrid integration allows you to use your existing SendGrid account as a Third-Party Sending Provider (TPSP). This means you can:
  • Send emails through SendGrid while using SendPost’s unified API
  • Receive and process SendGrid events (opens, clicks, bounces, etc.) in SendPost
  • View all email analytics in one centralized dashboard
  • Apply SendPost’s intelligent routing and throttling to your SendGrid traffic
Additionally, SendPost offers a SendGrid-Compatible API that allows you to migrate from SendGrid with minimal code changes.
