A scan reads your mailbox and builds a list of the senders that email you, with a way to unsubscribe from each one. Nothing is unsubscribed, moved or deleted by the scan itself. You choose what happens next. For each message, the scan looks in this order:
  1. The unsubscribe header. Most bulk senders add a hidden List-Unsubscribe header to their emails. It holds a web link, an email address, or both. If the sender also supports one-click unsubscribe, we can send the request without opening a web page.
  2. The message itself. If the header is missing, or is not a one-click link, the scan looks for an unsubscribe link in the body of the email. It recognises unsubscribe wording in English, German, French, Spanish, Italian, Dutch and Portuguese.
  3. An AI model, as a last resort. On paid plans, when neither step finds a link, the start of the email’s HTML may be sent to an AI model whose only job is to find the unsubscribe link. The privacy policy says exactly what is sent.
Each sender in your results shows which method was found: One-click, Body link, Mailto (an email address to write to) or Manual (a link you open yourself).

​
What is read and what is stored

To find a link in the body, we read the message’s HTML in memory. We never store message content. What we keep for each sender:
  • the sender’s name and email address;
  • one sample subject line;
  • how many emails they sent you, and the first and last dates;
  • the unsubscribe link and the method.
See Data and deletion for how to remove it.

Recommendations

The scan can score each sender from 0 to 100 for how likely it is to be unwanted marketing, with a one-line reason. To do this, an AI model is sent the sender’s name and address, one sample subject line and the number of emails. It is not sent the body of your emails. On the Free plan, a limited number of senders are scored each month, starting with the ones that email you most. Paid plans score every sender. See pricing.

How far back a scan goes

Every plan can scan the whole mailbox.
