Checked on arrival

Sender Safety Privacy Writing

Sender checks passed. No look-alike domain found.

Scored on arrival. You decide what to block.

How it works

## Running in three steps.

1. 01
   
   Mail arrives
   
   Checks run on arrival: sender authentication, links, attachments, wording and look-alike domains.
2. 02
   
   Read the verdict
   
   Four tiles sit on the message. Open one to read the reasons behind it.
3. 03
   
   Block the sender
   
   Block one address or a whole domain. The next message is refused with a report.
