97. Stop Spam: Review Unknown Senders
Published on: Jan 9, 2026
Episode summary
There is a simple feature that can help you greatly in the fight against phishing. Yet all the email providers I've checked, aside from Fastmail, lack this feature.
What is the feature? The ability to route emails you receive based on whether the sender is a known contact.
Here s how you use it:
1 - Set up a rule to route all email from unknown senders to an Unknown Sender folder.
2 - Go carefully through each email in that folder, and for any email you trust, add that sender to your contacts.
3 - For any email you don t trust, mark it as spam or block the sender.
Then, when a phishing email comes in trying to impersonate a sender you trust, it will end up in the "Unknown Sender" folder. This is the folder where you carefully review every email, and if it is pretending to come from a known sender, you will know it s a phishing attack.
