Lets you send transactional emails through Resend's API without writing the boilerplate yourself. You get two modes: single for one-off emails with attachments or scheduling, and batch for firing off up to 100 distinct emails in one call. The batch endpoint is worth knowing about if you're bumping into Resend's default 2 requests per second rate limit. This is from the official Resend team, has passed security audits from Gen Agent Trust Hub, Socket, and Snyk, and sits at 473 installs with 125 GitHub stars. Straightforward integration if you're already in the Resend ecosystem.
