How to Tell If an Unsubscribe Link Is Safe: 5 Signs
Before you click on any unsubscribe link, check these five red flags:
- Did you receive this email without signing up?
- Does the sender's address look suspicious?
- Is the email making you feel like you have to act fast?
- Does the unsubscribe link URL look suspicious?
- Does the email lack branding or look poorly made?
🚩 If you don't know who sent the email or didn't sign up for it, the unsubscribe link might just be there to make sure your email is still active.
🚩 Common signs of phishing are misspelled domains, random character strings, and addresses that don't match the brand name.
🚩 "Act now" and "your account will be closed" are examples of pressure tactics that make you click without thinking.
🚩 Before you click on the link, hover over it to see where it leads. Legitimate senders often route unsubscribe links through their email service provider, so the domain won’t always match. Be wary of URL shorteners, random strings, and domains that imitate a well-known brand.
🚩 Real companies use consistent branding. If an email claims to come from a big brand but lacks its usual logo, formatting, or footer details, treat it as suspicious.
⚠️ Don't click the unsubscribe link if you said "yes" to any of these. Instead, mark the email as spam or block the sender.
Confirm the sender’s email address
Before unsubscribing or blocking a sender, view the email address to be sure it’s not from a legitimate sender. It can be just as easy to confuse a valid sender with a spammy one and mistakenly unsubscribe or block them.
💡 This is where Clean Email’s Screener feature comes in handy by letting you review messages from unknown senders before they hit your inbox.
Use your email provider’s unsubscribe button
For newsletters you signed up for, the safest option is often your email provider’s built-in unsubscribe button instead of the link inside the email. In Gmail, open the message and click Unsubscribe next to the sender’s name; if the sender requires it, you’ll see Go to website instead. It may take a few days for the emails to stop. Learn more about unsubscribing through your email provider.
Report or block spam
Marking suspicious senders as spam helps your provider recognize future emails as junk and move them to the spam folder, and blocking senders keeps their emails from reaching your inbox. In the US, you can also report spam and scam emails to the FTC at ReportFraud.ftc.gov.
Risks of Unsafe Unsubscribe Practices
⚠️ What Not to Do:
- Do not click any links in the message.
- Do not open any attachments in the email.
- Do not reply to a spam or junk email.
These three “don’ts” are the most basic actions you should avoid, here’s why:
- Visiting links can lead to phishing attempts and activity tracking.
- Opening attachments that contain malware can affect your device security.
- Replying to junk mail can confirm to the sender that you have an active email account resulting in more spam.
Keep in mind that unsubscribing is only as good as the sender’s willingness to remove you from their mailing list. Check out more on this particular topic in our article "Does unsubscribing from emails work?"
