Emails are **indispensable to our operations** here at Unkey. They streamline our onboarding process, manage billing communications, and drive our marketing efforts. Our onboarding emails guide new customers through how Unkey works, while transactional emails keep them informed about billing statuses, such as overdue invoices. Additionally, our changelog updates are distributed via email, keeping all our customers in the loop about the latest enhancements and features.

Introducing Resend into our workflow was **straightforward and required minimal development effort.** We installed the SDK, utilized [React Email](https://react.email) to craft our emails, and smoothly transitioned to production.

Before Resend, handling email communications was filled with complications, specifically ensuring cross-compatibility across various email clients. Resend’s simplicity and reliability have been transformative for Unkey. It's incredible to **reliably send an email consistently to every user.**

Whenever challenges arose, the Resend support team was exceptional. They not only offered **personalized assistance** but also [pushed a PR to our open-source repository](https://twitter.com/chronark_/status/1773437626499903793) to help resolve an issue. Their level of support and guidance is **unmatched in this industry.**

Resend is the **fastest and easiest** way to send emails at scale.
