Unsubscribe, report or ignore? Handling mail you never wanted
October 12, 2026 · 2 min read
Unwanted mail comes in two flavours, and they deserve different treatment.
Legitimate senders you no longer want
A shop you bought from once, a newsletter you signed up for and forgot. These senders generally honour the unsubscribe link. In the United States, for example, the CAN-SPAM Act requires commercial senders to offer a way to opt out and to act on it within ten business days. Many large mailbox providers also show their own "Unsubscribe" button next to the sender name, based on information in the message header.
For these, unsubscribing is safe and effective.
Senders you never heard of
Here clicking anything is a bad idea. An unsubscribe link in genuine spam can work as a "yes, this address is read" signal, and the link itself may lead somewhere you do not want to go. In your real inbox, use the provider's Report spam button instead. It trains the filter and does not touch the sender's links.
On a temporary address
You get a third option that your real inbox does not have: leave. Messages here are removed after seven days, and an address you stop visiting simply fades out. No unsubscribing, no reporting, no filter rules.
That is also a good argument for using a temporary address first when you are unsure about a newsletter. Read a couple of issues here. If you like it, sign up with your real address and unsubscribe nothing.
