Why we started this blog

Email deliverability is complex. Between SPF, DKIM, DMARC, MX configuration, IP reputation, and evolving provider requirements, there is a lot to keep track of.

This blog will cover:

  • Email authentication — deep dives into SPF, DKIM, and DMARC configuration
  • DNS best practices — how to structure your email DNS for reliability
  • Deliverability engineering — practical advice for getting mail to the inbox
  • KumoMTA — guides for running and operating KumoMTA

What to expect

We will publish practical, actionable guides. No fluff, no marketing speak. Each post will give you something you can apply immediately to improve your email infrastructure.

Use our email analysis tool to check your domain's health, or dive into the individual tools for MX, SPF, DKIM, and DMARC records.

Stay tuned.
