Send Emails from Next.js with Hisend SDK

Sending transactional emails in Next.js should be incredibly simple. But if you are building an app for the European market, you quickly run into a wall: strict GDPR requirements, US-hosted servers, and sometimes overly complex APIs. In this quick tutorial, I will show you how to send emails in a Next.js App Router project using Hisend ( @hisend/sdk ) – an EU-hosted email API designed specifically for developers who want a clean Developer Experience (DX) and native data compliance. Let’s dive in. Prerequisites A Next.js project (App Router) Node.js installed Step 1: Set up your Hisend Account & Domain Before we write any code, we need to make sure your emails actually reach the inbox and don't end up in spam. Sign up: Go to hisend.app and create a free account. Create a Project: Set up your first workspace/project. Add your Domain: Enter the domain you want to send emails from (e.g., yourdomain.com ). Configure DNS: Hisend will generate specific DNS records (SPF, DKIM, and DMARC). Copy
