Resend

Email from your application that arrives – with templates you maintain like the rest of your code.

dectria sends transactional email with Resend: invitations, password links, notifications and reports from web applications and SaaS products. We use Resend in production in our own products.

We write the templates with React Email as TypeScript components – with the same tools as the frontend, versioned in the same repository and tested in all common email clients.

To make sure emails arrive, we authenticate the sender domain with SPF, DKIM and DMARC and track the delivery status of every message via webhooks.

What is Resend – and when is it worth it?

Resend is an email service with a lean API for emails that an application sends automatically. React Email, from the same team, describes email templates as React components instead of nested HTML tables.

Resend is worth it for applications that send invitations, notifications or reports, especially when the team already works with React. For newsletters with campaign planning and marketing automation, a specialized marketing tool is the better choice.

FAQ

Resend FAQ

Why Resend instead of SendGrid or Mailgun?
Because of the lean API, the typed SDK and React Email: templates are built with the same tools as the frontend. For purely transactional email, this is often faster to implement and easier to maintain. If you need extensive marketing features, established providers are the better fit.
What is React Email?
An open-source framework from the Resend team for building email templates as React components. Instead of writing HTML tables and inline CSS by hand, we work with type-safe components that are compiled into email-ready HTML at build time.
How reliable is email delivery with Resend?
The foundation is a properly authenticated sender domain: we set up SPF and DKIM as DNS records and define a DMARC policy. Via webhooks, we track the delivery status of every email, so we can react to bounces and complaints immediately. For high sending volumes, a dedicated IP address is an option.
Where does Resend process data?
Resend is a US company. We can have emails sent via the EU region in Ireland, but according to Resend, account data, logs and metadata are stored in the US. We sign the data processing agreement for the transfer. If all data must stay in the EU, we choose a European provider.
