Email Open Rate: What It Can and Can't Tell You

Understand email open rate, its limitations, and why clicks and business outcomes often deserve more attention.

The practical idea

Open rate estimates whether a message was opened, but privacy features and image-loading behavior can distort the signal. Use it as one directional metric rather than a complete measure of success.

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.
