After years of building and maintaining custom webhook delivery systems at scale, we decided to build the platform we wished existed. SendSend is the result — a delivery API that handles rate limiting, retries, and observability so you don't have to.
Every company that sends webhooks or notifications ends up building the same infrastructure: queues, rate limiters, retry logic, monitoring. It's complex, error-prone, and takes engineering time away from your core product.
SendSend provides all of this as a managed API. One integration gives you rate-limited delivery with automatic retries, real-time tracking, and the throughput to handle millions of events. You focus on what to send — we handle how it gets there.
