My favorite part of Resend is the straight forward syntax to sending an email and the fact that you can build your email templates in a React component.

SMTP compatibility meant I didn't have to rewrite a single template, just pointed nodemailer at Resend's server and moved on.

Setup took maybe 30 minutes including DNS verification. Works reliably, the logs actually show you what happened to each email.
