Every marketing email has an unsubscribe link, and most people have heard two opposite pieces of advice about it: "always unsubscribe" and "never click unsubscribe, it only confirms your address." Both are right, for different kinds of email. This guide shows you how to tell which kind you are looking at and the safest way to opt out of each.
The short answer
- You signed up, or it is a company you know: unsubscribe. It works, and it is the fastest fix.
- You have never heard of the sender, or it looks like a scam: do not click anything. Mark it as spam instead.
Why unsubscribing from real senders works
Legitimate companies have strong reasons to honour your request. In the United States the CAN-SPAM Act gives senders 10 business days to stop. Canada's anti-spam law (CASL) sets the same 10 business day limit, and in the EU and UK you can withdraw consent to marketing at any time. On top of the law, Gmail and Yahoo have required bulk senders since February 2024 to offer one-click unsubscribe and to process requests within two days. A sender that ignores this risks having all of its email sent to spam.
The safest way to unsubscribe: use your mail app's button
You often do not need the link inside the email at all. When a message includes the right technical header, your mail app shows its own unsubscribe control:
- Gmail: an "Unsubscribe" link next to the sender's name at the top of the message. Gmail also has a Manage subscriptions view in the side menu that lists the senders who email you most.
- Outlook: an "Unsubscribe" link above the message.
- Apple Mail: a banner at the top saying the message is from a mailing list, with an Unsubscribe button.
This is safer than the link in the footer because the request is sent by your mail provider. You never load a page controlled by the sender.
When you should not click unsubscribe
Spammers and scammers do not follow the law, so their unsubscribe link has no reason to work. It can do two things instead: tell them your address is real and read by a person, which makes it more valuable to sell, or send you to a page that asks for personal details. Treat the email as junk and leave the link alone if:
- You do not recognise the sender and never gave them your address.
- The sender's address does not match the company it claims to be. See how to check where an email really came from.
- The message shows other scam signs such as urgency, prizes or a request to "verify your account". Our list of phishing warning signs covers them.
- The unsubscribe page asks for a password, payment or more than your email address.
For these, use Report spam (Gmail) or Junk > Block sender (Outlook). Reporting also trains the filter, so similar messages are caught before you see them.
What a normal unsubscribe page looks like
A legitimate opt-out takes one or two clicks. It may show a list of email types to choose from, or ask why you are leaving, and you can skip the question. It should never ask you to log in with a password you do not have, to pay, or to fill in your name, address or phone number.
If the emails keep coming
- Wait a few days. Campaigns that were already scheduled may still arrive.
- Check which address they are sending to. You may be subscribed twice, for example with an old address that forwards to your current one.
- Look for account settings. Shops and apps often keep marketing preferences inside your account, separate from the email link.
- Block or filter the sender. A filter that sends everything from that domain to trash ends the problem on your side.
- Report it as spam. A company that ignores opt-outs has earned it.
How to get fewer of these emails in the first place
- One-time sign-ups: use a temporary email address for downloads, trials and anything you will not return to. The newsletter that follows goes to an inbox that expires.
- Accounts you keep: use an alias, so you can switch off one address without touching the rest. See how to set up an email alias.
- At checkout: untick the "send me offers" box. It is often ticked for you.

Frequently asked questions
Does unsubscribing confirm my email address to spammers?
Only if the sender is a spammer. A real company already knows your address is valid, because you gave it to them. With unknown senders, clicking can confirm the address is active, which is why reporting as spam is the better choice.
Is it better to unsubscribe or mark as spam?
Unsubscribe from senders you signed up with, and mark as spam anything you never asked for. Marking a newsletter you did subscribe to as spam works too, but it is less reliable than opting out.
Are bulk unsubscribe services safe?
They need access to read your whole inbox to work, and some have funded themselves by selling anonymised data about what their users buy. Read the privacy policy first, or use the tools already built into your mail app.
