CAN-SPAM Act Requirements
While the CAN-SPAM Act includes several rules for email senders, a few directly affect how unsubscribe requests should be handled.
- Emails must include a clear and easy way to unsubscribe from future marketing messages.
- Unsubscribe requests must be honored within 10 business days and remain valid for at least 30 days after the email is sent.
- Senders are not allowed to sell or transfer email addresses of users who have opted out — except for compliance purposes.
In practice, legitimate companies follow these rules. But spam senders often ignore them, which is why unsubscribing doesn’t always work as expected — and may even lead to more unwanted emails.
This gap between regulation and reality is one of the main reasons users continue to receive unwanted emails.

One reason you might see more emails after unsubscribing is that some senders treat the action differently. For legitimate companies, clicking “unsubscribe” simply removes you from their mailing list. But for less trustworthy senders, it can signal that your email address is active and monitored.
This is where the problem often starts — the same action that should remove you from a list can instead confirm that your inbox is active.
In those cases, your address may become more valuable and could be reused, shared, or even sold across multiple mailing lists, which can result in an increase in unwanted emails.
A super untrustworthy sender will not only violate compliance, but may also use unsafe opt-out websites to collect additional personal information or direct you to malicious links.
Additionally, spammers may participate in email address harvesting where they buy, sell, or trade email address lists with other spammers or use bots or even deceptive means to obtain email addresses.
Is It Better to Block or Unsubscribe?
In general, it’s best to unsubscribe from legitimate senders and block or report suspicious ones as spam.
Unsubscribe when:
- The sender is a known company or service you signed up for
- The email looks trustworthy and follows compliance rules
- You want to stop newsletters or promotions
Block or mark as spam when:
- The sender looks unfamiliar or suspicious
- The email contains poor formatting, odd links, or urgency tactics
- You suspect phishing or data harvesting

FAQ
How long does it take to stop emails after unsubscribing?
Under laws like the CAN-SPAM Act, companies have up to 10 business days to process your request. During this time, you may still receive messages from the sender.
Why do I keep getting emails from the same sender?
This can happen if the sender uses multiple mailing lists, delays processing your request, or ignores unsubscribe rules altogether. Some companies also send transactional emails that are not affected by unsubscribe requests.
Does unsubscribing remove me from all mailing lists?
No. Unsubscribing only removes you from a specific sender or list. If your email address has been shared or sold, you may continue receiving emails from other sources.
