Best for

Developers who want to send product email from code without wrestling with legacy ESP consoles.

Why it deserves attention

Resend is an email API with official SDKs for Node.js, Python, PHP, Ruby, Go, Rust, Java, Elixir and .NET, plus REST and SMTP for everything else, and it treats React Email as a first-class way to build templates. The dashboard covers domains with DKIM, SPF and DMARC setup, logs, webhooks, broadcast and inbound email, and the free plan sends 3,000 emails a month with three domains and three inboxes. Paid plans are $20/month for 50,000 emails and $90/month for 100,000, with extra messages at $0.90 per thousand. Deliverability tooling includes shared IPs maintained by Resend and dedicated IP add-ons. The caveats: it is younger than SendGrid or Postmark, so some enterprise integrations and marketing-automation features are thinner, and as with any ESP your sender reputation still depends on how you treat your list.
