Why we built mailkube
Email is core infrastructure, and most platforms treat it as a marketing channel with an API attached. Here is what the other view forced us to build.
Email delivery, in practice
Guides, tutorials, and product news for developers who send email.
RSS feedSend email from a serverless function
Send email from a serverless function on Cloudflare Workers, AWS Lambda or Deno with an SDK that needs no polyfills and no nodejs_compat flag.
Send email from Express, Fastify, Next.js
Send email from a Node.js server: Express and Fastify routes, Next.js App Router handlers, NestJS providers, and webhook receivers that verify.
SPF, DKIM and DMARC: what each proves
How the three email authentication standards work together, what each record actually proves, and where each DNS entry belongs before your first send.
Send your first email from Node.js
Send email from Node.js with the mailkube SDK: install, key, first message, then scheduling, templates, tags, topics and webhook verification.
Message tags and topics are generally available
Email message tags label any send with your own metadata, topics decide who receives it, and both break down on your sending dashboard.
