No third parties are contacted when clicking a link.
Links in the eMail may initially point to third party services such as trackers, which will forward the user to the correct address later. This check detects this kind of tracking behavior. Warning: This check currently sometimes returns incorrect results, which will be resolved in the near future. More information.
Conditions for passing: This check passes if no connections to third parties are established when clicking links from the Mail.

A/B Testing unreliable
No indications of A/B testing were found.
Service providers may perform so-called A/B testing by sending different versions of Emails to different recipients to test which wording generates more clicks. While this is not a privacy problem in itself, it indicates that marketing analysis is taking place. More information.
Conditions for passing: This check fails if we observe indications that A/B testing is being performed.
Potential scan errors: This check works by finding and comparing related pairs of Emails sent to different identities. If Emails are matched incorrectly, this check may give incorrect results. As A/B testing is a random process, we may also miss instances of A/B testing if only a small number of identities is signed up for the service.Result wrong? report error
Third party spam reliable

Service providers may intentionally or unintentionally disclose your eMail address to third parties, including spammers. We try to detect this by tracking if identities associated with this service start receiving eMails from other senders. More information.
