One of the ways that we find newsletters and subscriptions in your email account is by scanning the emails for words and patterns that are commonly found within these types of email. Words like “unsubscribe” and “opt-out”.
If you provide other languages that can be found in your inbox then we’ll search for the equivalent words in your language too!
