Open Rate

TL;DR

Open rate is the percentage of delivered emails that recipients open. Apple's Mail Privacy Protection has made it much less reliable since 2021.

How SaaStorm approaches it

Because privacy features inflate opens, we treat open rate as a rough directional signal at best.

Clicks, replies and downstream conversions are better measures of whether email content is working.

Turn search visibility into pipeline

We help European SaaS teams build an organic engine across SEO, AEO and content, measured in qualified pipeline.
