#3847 [Core feature] Flyteadmin email publisher Issue created by pingsutw Motivation: Why do you think this is important? Currently, FlyteaAmin sends an event to aws SNS first. (admin event publisher -> SNS -> SQS -> admin email processor) We can have an admin email publisher, which directly sends the email without SNS/SQS, and we should only use it in the sandbox. The new email publisher can be added to here Goal: What should the final outcome look like, ideally? We are able to use email/slack notifications in the sandbox. Describe alternatives you've considered Add aws sns / sqs config in the sandbox environment.
