About Resend
Resend ships SSO and enters the enterprise conversation as its product surface broadens.
Resend has moved well beyond its original transactional email API. The last few weeks show it filling out a complete email operations stack: segment management, table components for Broadcasts and Templates, a link checker for pre-send validation, and API endpoints for metrics, automation duplication, and email sharing. The cadence is steady and the feature breadth is growing across both the developer API and the marketing-facing tooling.
