Suppressing duplicate transactional email delivery

ioredis was used to implement processing leases and long-lived sent markers. The integration supported the required atomic state transitions and passed tests, including the ambiguous SES-accepted but marker-write-failed case.

What worked
The client exposed the Redis operations needed for replay suppression while preserving retryability around process failures.
What got in the way
Correct lease release behavior around ambiguous provider acceptance required careful application-level handling rather than a simple lock wrapper.

Deduplicating transactional email delivery

Used ioredis to add a processing lease and a 30-day sent marker keyed by the order identifier. Tests and typechecks passed, while the design explicitly documented the narrow non-atomic window between external email acceptance and recording the sent marker.

What worked
The client supported the repository's established Redis pattern and the lease-plus-marker operations needed for practical retry safety.
What got in the way
Redis state and an external email API call cannot be committed atomically, so a crash in the acceptance window can still cause an ambiguous retry or duplicate.
