How can I prevent Microsoft Defender from triggering unwanted one-click unsubscribes?

Email marketer from Reddit explains that closely monitoring your unsubscribe rates and comparing them to industry benchmarks can help identify unusual spikes. If you notice a significant increase, investigate potential causes such as Microsoft Defender's link scanning. This allows you to take proactive measures to address the issue.

Email marketer from ActiveCampaign Community suggests excluding Microsoft IPs from link tracking, as their click-throughs can trigger false positives. This involves identifying and filtering out Microsoft's IP ranges in your tracking settings.

Email marketer from Email Geeks shares experience with elevated unsubscribe click events due to Microsoft Defender, particularly affecting Office 365 accounts. Recommends escalating the issue to Office 365 for remediation and being cautious when adding new domains, advising testing and verification if Office 365 is crucial to their user base.

Email marketer from SendGrid shares maintaining a suppression list of known bot IPs and user agents. If you can identify traffic from Microsoft Defender's link scanning, add those IPs and user agents to your suppression list to prevent them from triggering unsubscribes. Suppressing their known signatures can reduce the false unsubscribes.

Email marketer from Neil Patel Blog shares that segmenting your email list to target only engaged subscribers can prevent this issue. Focus on subscribers who have actively opened and clicked on your emails. This reduces the chances of sending emails to inactive addresses that may be scanned by Microsoft Defender, leading to accidental unsubscribes.

Email marketer from MailPoet explains using a confirmed opt-in process can help. When a new subscriber signs up, they receive an email asking them to confirm their subscription. This ensures that only genuine subscribers are added to your list, which can reduce the likelihood of Microsoft Defender triggering unsubscribes due to bot activity.

Email marketer from Email Geeks echoes Steve's advice and advises against placing one-click unsubscribe links in the email body, as it's often link-checked by MPBs, artificially increasing unsubscribe rates. He also recommends following RFC8058 to implement the feature in email headers appropriately, using one link to a webpage and a POST action for MPBs.

Email marketer from Stack Overflow explains adding a confirmation page after a user clicks the unsubscribe link can help prevent unwanted unsubscribes. This page requires the user to confirm their decision before the unsubscription is processed, reducing the likelihood of accidental clicks or bot-triggered unsubscribes.

Email marketer from EmailToolTester suggests using a double opt-in process for subscribers. Requires users to confirm their subscription by clicking a link in a confirmation email. This ensures valid subscribers, reducing the likelihood of false unsubscribes triggered by bots like Microsoft Defender.

Email marketer from Litmus recommends A/B testing different placements and designs for your unsubscribe links. Test how Microsoft Defender interacts with these variations and identify which options are less likely to trigger unwanted unsubscribes. Track which version has the best user experience with the least amount of automatic clicks.

Email marketer from Gmass recommends throttling your sending speed to avoid triggering spam filters. Sending emails too quickly can cause Microsoft Defender to flag your emails as suspicious and potentially trigger automated link checks. Gradually increase your sending volume to establish a positive reputation.

Expert from Email Geeks explains link checkers should not unsubscribe users, and a click on a link in the email body unsubscribing a recipient indicates an incorrect setup.

Expert from Word to the Wise shares you can protect against crawler unsubscribes by not immediately unsubscribing users who click the unsubscribe link. Instead, direct them to a landing page where they must confirm their decision to unsubscribe. This prevents bots and crawlers from automatically unsubscribing users.

Expert from Email Geeks explains that clicking a link in the email body should open a webpage for unsubscription confirmation, requiring a button click (HTTP POST) to unsubscribe. He states this has been best practice for a long time, suggesting that immediate unsubscription via a single click should be avoided.

Expert from Spam Resource warns against using one-click unsubscribe links due to the risk of automated systems, including security scanners like Microsoft Defender, triggering them and causing unintended unsubscribes. She emphasizes that these systems don't read instructions and follow links indiscriminately.

Expert from Word to the Wise explains providing an easily accessible unsubscribe option will reduce the likelihood of users marking your messages as spam. Making the unsubscribe process straightforward encourages recipients to opt-out gracefully instead of reporting the email as unwanted.

Documentation from RFC Editor explains that using a 'mailto:' List-Unsubscribe header, rather than a one-click HTTP unsubscribe, may help. The 'mailto:' option requires a user to confirm their unsubscription by sending an email, reducing the risk of accidental unsubscribes triggered by automated link checks.

Documentation from Microsoft explains configuring Safe Links settings in Microsoft Defender for Office 365. By adjusting the settings, you can control how links are scanned and potentially reduce the frequency of automated clicks on unsubscribe links. Consider excluding specific URLs or domains from Safe Links scanning to prevent unwanted interactions.

Documentation from Microsoft shares how to implement email authentication protocols (SPF, DKIM, and DMARC) correctly. Proper authentication ensures that your emails are recognized as legitimate, reducing the likelihood of them being flagged by Microsoft Defender and preventing false unsubscribe triggers. It validates that the email truly came from the domain it claims to be from.

Documentation from SparkPost explains setting up Feedback Loops (FBLs) with Microsoft. FBLs provide you with data on spam complaints from Microsoft users, allowing you to identify and address potential issues that may be causing your emails to be flagged. It helps you understand and mitigate the reasons behind unsubscribes and spam complaints.
