Why do I keep receiving emails after unsubscribing?

Key findings

• Processing delays: Legitimate senders often have a grace period of a few days to process unsubscribe requests across all their systems. Emails might still be in the queue during this time.
• Multiple lists: You might be subscribed to several different mailing lists or segments within the same company. Unsubscribing from one does not automatically remove you from all. Always check for a preferences page to manage all subscriptions.
• Unethical practices: Some less reputable senders, particularly those involved in spam, may ignore unsubscribe requests or sell your email address to other spammers. These practices are illegal under laws like the CAN-SPAM Act in the U.S.
• Segmentation issues: Even with ethical senders, poor segmentation or database management can lead to users being inadvertently kept on a list after unsubscribing from a related one.
• Transactional emails: Unsubscribing from marketing emails typically does not affect transactional emails related to purchases, account activity, or service updates, which are often legally required or essential.

Key considerations

• Wait period: Allow up to 10 business days for unsubscribe requests to fully propagate through a sender's system, as per compliance regulations.
• Review email addresses: Ensure you are unsubscribing the exact email address that is receiving the unwanted mail. Slight variations can lead to continued emails.
• Contact support: If emails persist after a reasonable period, consider contacting the sender's customer support directly to request manual removal from all lists. This can sometimes resolve issues that automated systems miss.
• Report as spam: If all else fails and you believe the sender is ignoring your request, mark the emails as spam. This action helps your email provider identify and blocklist malicious senders, impacting their sender reputation and potentially causing their domain or IP to be added to a blocklist.
• Monitor deliverability: From a sender's perspective, consistently monitoring deliverability and unengaged subscribers is essential to prevent user frustration and maintain a healthy email program.

Key opinions

• Shared frustration: Many marketers experience the same problem as consumers, receiving emails from senders who ignore unsubscribe requests or rely on outdated opt-in consent.
• Impact on perception: Persistent unwanted emails, especially after unsubscribing, reflect poorly on a brand and can be seen as unethical or spammy marketing behavior.
• Opt-out failures: Even minor failures in the opt-out process can lead to a large number of frustrated individuals, particularly for large mailing lists.
• Beyond email: The issue extends to other communication channels like SMS and phone calls, where opt-out mechanisms are often less robust.
• Consumer action: The common response to persistent unwanted emails is to mark them as spam, which has negative consequences for the sender's deliverability.

Key considerations

• Clear unsubscribe paths: Ensure that unsubscribe links are highly visible and functional in every email, making it easy for users to opt out when desired.
• Preference centers: Implement a robust preference center where subscribers can manage all their communication preferences and lists, rather than a simple unsubscribe link for a single list. This is also why Gmail launched its 'Manage Subscriptions' feature.
• Timely processing: Ensure unsubscribe requests are processed swiftly, ideally within 24-48 hours, to minimize recipient frustration and comply with legal requirements.
• Regular list hygiene: Periodically clean your email lists to remove inactive or unengaged subscribers. This reduces the chances of them reporting your emails as spam, which can harm your domain reputation.
• Compliance awareness: Marketers must be fully aware of and compliant with anti-spam laws in all regions they operate, such as CAN-SPAM and GDPR.

Key opinions

• Reputation damage: Experts agree that failing to process unsubscribes swiftly leads to increased spam complaints, harming a sender's reputation and leading to lower inbox placement or even being placed on a blacklist.
• Legal ramifications: Ignoring unsubscribe requests can result in legal action, fines, and serious compliance issues under various anti-spam laws globally.
• Technical complexity: Ensuring a complete unsubscribe requires sophisticated database management and integration across all sending platforms, which can be a technical challenge for some organizations.
• ISP response: Internet service providers (ISPs) typically do not block a major sender based on a single spam complaint, but repeated complaints indicate broader issues that can lead to deliverability problems.
• User experience: Prioritizing the user's desire to opt-out is paramount for maintaining trust and a positive brand image.

Key considerations

• Feedback loops (FBLs): Senders should leverage FBLs provided by ISPs to automatically detect and remove users who mark emails as spam, effectively honoring indirect unsubscribe requests and protecting sender reputation.
• List segmentation: Implement granular list segmentation and ensure that unsubscribing from one category doesn't inadvertently keep users on others, unless explicitly desired via a preference center.
• DMARC monitoring: Use DMARC monitoring to gain visibility into email authentication and delivery, which can indirectly highlight issues if user complaints are high.
• IP and domain reputation: Regularly check your IP and domain against public blocklists. A high volume of spam complaints from ignored unsubscribes can lead to blacklisting, severely impacting deliverability.
• Abuse desk contacts: While single complaints rarely trigger a shutdown, sustained issues should prompt direct communication with the sender's email service provider's abuse department.

Key findings

• Legal requirement: Laws like the CAN-SPAM Act mandate that commercial emails must include a clear and conspicuous way for recipients to opt out of receiving future messages. This right applies to primary advertising messages.
• Timely processing: Unsubscribe requests must be honored within a specific timeframe, typically 10 business days, by law.
• No additional charges: Senders cannot charge a fee, require personal information beyond an email address, or make recipients take steps other than sending a reply email or visiting a single page on an internet website to opt out.
• Distinguishing email types: Regulations often differentiate between commercial and transactional emails. Unsubscribing applies to commercial emails, while transactional messages (e.g., receipts, account updates) may still be sent.
• Penalties for non-compliance: Violations of anti-spam laws can result in significant financial penalties and legal action from regulatory bodies.

Key considerations

• Clear identification: All commercial emails must clearly identify the sender and provide a physical postal address.
• Honoring requests: Even if the email is not explicitly 'commercial,' best practices suggest honoring all unsubscribe requests for a positive user experience.
• No re-adding: Once a recipient has opted out, senders are prohibited from selling or transferring their email address to another entity for sending commercial messages, unless for compliance or audit purposes.
• Multiple unsubscribe options: While not always legally required, offering a preference center allows users to refine their subscriptions, reducing outright unsubscribes and complaints.
• Automated systems: Relying on automated systems to process unsubscribes quickly and accurately is critical for scalability and compliance, rather than manual processing.
