Summary
Email marketing opt-out requests, also known as unsubscribe requests, are generally considered permanent. Under significant anti-spam regulations such as the CAN-SPAM Act in the United States, these requests do not expire and must be honored indefinitely unless the individual explicitly opts back in. Attempting to re-engage or re-add a subscriber after they have opted out, without obtaining new, affirmative consent, is a violation of legal statutes and ethical marketing practices. This approach is critical not only for legal compliance but also for maintaining a positive sender reputation and ensuring good inbox placement.
Key findings
- Permanence: Opt-out requests are permanent and do not expire under major anti-spam laws like CAN-SPAM.
- Legal obligation: Marketers are legally obligated to honor unsubscribe requests indefinitely unless the recipient provides new, explicit consent.
- Re-engagement: Re-engaging unsubscribed contacts requires a fresh, affirmative opt-in, typically obtained through separate channels.
- Compliance risk: Failing to honor opt-outs promptly and permanently can lead to significant legal penalties and severe damage to sender reputation.
Key considerations
- Data hygiene: Implement robust systems to manage and suppress unsubscribed email addresses, ensuring list quality and compliance.
- Legal adherence: Stay informed about and comply with all applicable regional email marketing laws, including CAN-SPAM, GDPR, and CASL. You can find more details on legal timeframes for unsubscribing.
- Ethical practice: Prioritizing the user's choice and respecting their decision to opt out fosters trust and positively impacts your overall deliverability, as discussed in why companies ignore opt-out requests.
- Reputation impact: Sending emails to opted-out users significantly increases the risk of spam complaints and being placed on a blocklist, severely harming your sender reputation. For more information, refer to the FTC's CAN-SPAM Act compliance guide.
What email marketers say
Many email marketers unequivocally agree that opt-out requests must be treated as permanent. They stress that respecting a subscriber's decision to unsubscribe is paramount for both ethical marketing practices and maintaining a strong sender reputation. Attempting to re-add or re-engage opted-out contacts without explicit, new consent is largely seen as counterproductive, disrespectful to the individual, and potentially detrimental to email deliverability and overall brand trust. Marketers often warn that such actions can lead to compliance issues and negative impacts on campaign performance.
Key opinions
- Opt-outs are permanent: There is a widespread consensus that unsubscribe requests do not expire and must be honored indefinitely.
- Ethical imperative: Respecting user preferences is viewed as a fundamental ethical principle in email marketing, fostering trust and a positive brand image.
- Violation risk: Re-sending to opted-out users risks violating both legal regulations and the terms of service set by Email Service Providers (ESPs).
- Reputation damage: Sending to unsubscribed contacts severely harms sender reputation, leading to increased spam complaints and reduced inbox placement rates.
Key considerations
- Alternative channels: While email re-engagement for unsubscribed users is generally forbidden, marketers can utilize other marketing channels to encourage a fresh opt-in.
- Consent management: Implement robust systems to manage consent and ensure all unsubscribe requests are honored promptly, typically within 10 business days. Learn more about best practices for unengaged subscribers.
- User experience: Prioritizing the user's experience and choice, even when they opt out, contributes to a healthier email ecosystem.
- List health: Regularly cleaning your email list of unsubscribed users is crucial for overall list health and deliverability. Consider when to remove unengaged subscribers. For more best practices on handling unsubscribes, refer to Campaign Monitor's unsubscribe best practices.
Marketer view
Marketer from Email Geeks explains: "Opt-out requests are permanent. You don't even have to consider CAN-SPAM or GDPR if you simply respect spam complaints and unsubscriptions. This shows respect for your customers."
Marketer view
Marketer from Email Geeks advises: "STOP means STOP. Trying to retarget someone who has opted out through another channel is disrespectful. Remember, this is a person, not just an email address or a phone number."
What the experts say
Email deliverability experts are in strong agreement that email marketing opt-outs are permanent and do not expire. They underscore the severe legal ramifications under laws like the CAN-SPAM Act and the significant negative impact on sender reputation and inbox placement if these requests are not strictly honored. Experts emphatically advise against any practice that attempts to re-add or re-engage users who have explicitly opted out, citing it as detrimental to email program health and ethical standards.
Key opinions
- Legal non-expiration: Experts confirm that opt-out requests have no expiration date legally and must be honored permanently.
- Reputation risk: Ignoring unsubscribes is widely regarded as extremely detrimental to sender reputation, leading to higher spam complaint rates and blocklist placements.
- Compliance paramount: Strict adherence to unsubscribe laws is considered non-negotiable for maintaining a healthy and effective email program.
- Ethical imperative: Beyond legalities, it is deemed unethical to disregard a subscriber's explicit request to stop receiving emails, emphasizing respect for the individual.
Key considerations

- ESPs and terms: Email Service Providers (ESPs) typically have stringent terms of service that prohibit re-mailing unsubscribed users, leading to potential account termination.
- Proactive suppression: It is essential to maintain robust suppression lists to prevent any accidental re-mailing. This is a critical part of sender reputation management.
- Clear communication: Ensure your unsubscribe process and policy are transparent and unambiguous to avoid any confusion. For details on whether it is legal to opt users back in, see our related content. More information on CAN-SPAM is available from the Optizmo blog on CAN-SPAM.
Expert view
Deliverability expert from Email Geeks confirms: "Opt-outs are absolutely permanent. The company violating this was also violating CAN-SPAM and likely their ESP's terms of service. It's fundamentally disrespectful to re-engage them."
Expert view
Email deliverability consultant from Email Geeks clarifies: "You may retarget contacts on other channels to encourage them to opt back in, which creates a valid new opt-in. However, opt-outs themselves do not expire."
What the documentation says
Official documentation from regulatory bodies, particularly the Federal Trade Commission (FTC) regarding the CAN-SPAM Act, explicitly states that email marketing opt-out requests do not have an expiration date. This means that once a consumer opts out, their preference must be honored indefinitely unless they proactively choose to opt back in. Legislative history indicates that Congress deliberately chose not to include a time limit on these requests, emphasizing the permanent nature of an unsubscribe.
Key findings
- No expiration limit: The CAN-SPAM Act, as clarified by the FTC, does not impose any time limit on the duration of opt-out requests.
- Perpetual honor: Opt-out requests must be honored in perpetuity, or until explicitly revoked by the consumer through a new opt-in.
- Legislative intent: Congress deliberately chose not to include an expiration clause for opt-outs in the original legislation, reinforcing their permanent status.
- Prohibition on fees: Documentation also prohibits charging any fee for a user to opt out of commercial email messages.
Key considerations
- Strict adherence: Businesses must strictly adhere to the legal requirements for processing and permanently maintaining opt-out requests.
- Timely processing: Opt-out requests must be honored promptly, typically within 10 business days of receipt. More details on how long email consent lasts.
- Clear instructions: Provide a clear and conspicuous mechanism for opting out in every commercial email sent, ensuring ease of use for subscribers.
- Record-keeping: Maintain accurate and indefinite records of all opt-out requests to demonstrate compliance. Refer to CAN-SPAM record-keeping requirements. Official regulations regarding the scope and duration of opt out are available.
