Email Deliverability: A Practical Guide

Understand the factors that affect whether legitimate email reaches subscribers and how sender practices fit together.

The practical idea

Deliverability is the ability of legitimate email to reach recipients rather than being filtered or rejected. Authentication, reputation, permission, content and engagement all contribute.

Build the simplest useful version

Define the audience and desired outcome first. Then choose the minimum process and tooling needed to deliver a good subscriber experience. Add complexity only when a real limitation appears.

Common mistakes

Avoid collecting addresses without clear permission, creating automation nobody maintains, measuring vanity metrics without business context, and buying software before defining the workflow it needs to support.
