Privacy Policy

Last updated: September 2026

This site (subjectlinetesting.com), operated by Xeio Ltd, is a static website. We keep data collection to a minimum.

Analytics

We use Umami, a privacy-friendly analytics tool, to understand how many people visit our pages and which content is popular. It collects aggregated, anonymised usage data and does not use tracking cookies or build advertising profiles of you.

Purchases

When you buy the Email Emoji Playbook, the transaction is handled by Gumroad. Gumroad collects the information needed to process your payment and deliver the product (such as your email address and payment details) as an independent data controller, under its own privacy policy. We receive limited order information, such as your email address, so we can provide the product and support.

Third-party services

Some pages load Google Fonts (for the site's typeface) and the Gumroad checkout script. These providers may receive your IP address as a normal part of serving those resources.

Your rights

Depending on where you live, you may have rights to access, correct or delete the limited personal data we hold about you. To make a request, email [email protected].
