Resend

Resend is an email infrastructure platform designed to help developers reliably send transactional and marketing emails at scale. It focuses on improving deliverability so that critical messages such as password resets, order confirmations, and product updates consistently reach user inboxes instead of spam folders. Resend provides a modern API and tooling that integrates easily into existing applications and workflows.

Key features include a developer-friendly REST API and SDKs for popular languages, native support for frameworks like Next.js, and seamless integration with email providers such as AWS SES. Resend offers email templates, including React-based templates, to standardize and personalize content without complex HTML. It provides detailed event tracking and logs for opens, clicks, bounces, and failures, enabling teams to monitor performance and troubleshoot issues quickly. Built-in support for domain authentication (SPF, DKIM) and suppression lists helps maintain sender reputation and improve deliverability.
