Yes, many production applications use Resend. However, it's younger than SendGrid or Postmark with a shorter track record at very high scale. For most applications, Resend's reliability is excellent. For mission-critical enterprise email where a decade of deliverability data matters, consider more established alternatives.
Resend has dramatically better developer experience — cleaner API, better documentation, modern dashboard, React email support. SendGrid has more features (marketing email, inbound parse, email validation), a longer track record, and better deliverability infrastructure at scale. Choose based on whether DX or feature completeness matters more.
Yes. React Email is optional. Resend's API accepts plain HTML and text content. The React integration is a bonus for React teams but not required. You can use Resend with any framework or language through the REST API.
Good, with proper domain authentication. Resend handles SPF, DKIM, and DMARC configuration. Inbox placement rates are competitive with other major providers. For the highest deliverability, ensure proper domain warmup and authentication — Resend's dashboard guides you through this.
