Sending transactional email
shouldn't be this hard.

@
DNS verification001

Tedious DNS configuration.

Configuring SPF, DKIM, and DMARC for custom domains is error-prone. One wrong entry can silently tank your sender reputation.

Template design002

Broken HTML layout code.

Writing responsive email layouts in raw HTML is a nightmare. Building a custom react-email rendering pipeline requires major engineering effort.

SDK Integration003

Coupled API boilerplate.

Wiring up email sending SDKs directly into every microservice creates tight coupling, making it difficult to manage domains and configurations centrally.

Delivery events004

Invisible email tracking.

Getting real-time delivery logs, open rates, and bounce alerts shouldn't require building a separate analytics and webhook ingestion platform.

Complete email workflow.
Built for developers, powered by Resend.
