Amazon Pinpoint is Shutting Down: A Practical Migration Guide (and How One Tool Can Replace All Four)
Amazon Web Services will end support for Amazon Pinpoint on October 30, 2026, according to OneSignal's migration guide. AWS's own documentation directs Pinpoint customers to four separate services—Amazon Connect, Amazon Kinesis, Amazon SES, and AWS End User Messaging. OneSignal argues this fragmentates workloads and pitches its own platform as a single replacement covering journeys, segmentation, push, in-app, email, and SMS/RCS. The article includes a practical migration checklist and a call to plan ahead of the hard deadline.
- Amazon Pinpoint support ends on October 30, 2026; Pinpoint stopped accepting new customers in May 2025.
- AWS's migration guide directs Pinpoint customers to Amazon Connect, Amazon Kinesis, Amazon SES, and AWS End User Messaging.
