Ordinarily, when we receive commercial advertisements or spam emails, it becomes second nature to click the “unsubscribe” link typically found at the bottom. Applications such as Apple’s native Mail app even enhance user convenience by detecting these options and displaying an unsubscribe prompt at the top of the message.
However, TK Keanini, Chief Technology Officer at DNSFilter, advises against indiscriminately clicking these unsubscribe links. Doing so may sometimes expose users to significant risks. According to data, approximately one in every 644 clicks leads users to potentially malicious websites.
This perspective mirrors concerns associated with unsubscribing from spam text messages. Since such emails and messages are often broadcast in bulk, any response—including a request to unsubscribe—can inadvertently confirm to the sender that the recipient’s email address is both active and valid.
Armed with this information, spammers may then escalate their targeting efforts, populating new databases with verified addresses to bombard with fresh waves of spam. From this standpoint, blindly clicking unsubscribe links may indeed be counterproductive, though nuance is required depending on the context.
For example, if the sender is a legitimate service the user subscribed to, unsubscribing from promotional emails is generally safe. Some websites allow users to manage subscription preferences via account settings. However, it’s essential to verify that the unsubscribe link is not part of a phishing scheme.
In cases where malicious actors impersonate reputable companies—such as Google—and embed a counterfeit unsubscribe button, clicking that link could redirect users to phishing sites. If such a site prompts for login credentials, entering them could lead to a severe breach of personal data.
Keanini recommends staying within the safety of your email client. For instance, when using Apple Mail, tapping the unsubscribe option sends an automated email to process the request—without redirecting the user to external websites—thus mitigating the risk of exposure to phishing attacks.
Cybersecurity firm Zenity further warns that unchecked unsubscribe links can redirect users to fraudulent sites, where login credentials may be stolen under false pretenses or where malicious software might be deployed on the user’s device.
Therefore, experts agree: the safest method for unsubscribing involves using email client-supported unsubscribe headers—such as those used in Apple Mail—which operate independently of the message body and do not require users to follow external links.
Ultimately, regardless of the method, users should always scrutinize the sender and the link address. For unfamiliar services, it is safer to block the sender rather than engage. For known services, users should verify the link before confirming the unsubscribe action. Under no circumstance should one input credentials or download software from such prompts.
