[Lenny's Data](https://lennysdata.com) gives my subscribers a unique dataset to build with. It includes all of Lenny's Newsletter 350+ posts and 300+ podcast transcripts, in clean markdown, plus an MCP server, and a GitHub repo.

When I started the project, I asked **Claude Code** what it would recommend for email. When it recommended Resend, I checked out the website (which was super slick) and told it to start building.

Within a few minutes, it finished building the entire magic link auth flow. I provided a **Resend API key and a few parameters**—that was it! I was able to start sending auth emails within minutes.

Resend is the infrastructure layer that I don't need to ever think about. It's reliable, invisible, and **easy to implement for any agent**. The auth flow gives me peace of mind, and lets me focus on building the product.

The few times I had questions, the response was **super quick**. The CEO even jumped on personally to help resolve my questions.

Resend is your **magical email infra.**
