Why Older Salesforce Marketing Cloud Email Links Are Suddenly Expiring
If your audience is suddenly seeing “Your link has expired” when clicking an older email, it is not a campaign mistake. A recent Salesforce Marketing Cloud security update has quietly changed how legacy email links behave, creating unexpected implications for compliance, customer trust, and long-tail marketing journeys.
What Salesforce Changed in SFMC and Which Emails Are Affected
Following a security-related update implemented this week, Salesforce Marketing Cloud (SFMC) has enforced expiry on wrapped links contained in emails sent prior to 21 January. As of now, those links no longer redirect to their original destinations when clicked.
Although Salesforce has notified customers, many teams are only becoming aware of the issue as recipients revisit older emails. In practice, this means links that were valid at the time of send may now return an error message.
The challenge extends beyond broken calls to action. In some cases, unsubscribe links may also be affected. In regions where regulations require unsubscribe mechanisms to remain functional for extended periods, this introduces potential compliance exposure. The update is security-driven and intentional, but it reveals a gap many organisations did not realise existed: the assumption that responsibility ends once an email is delivered.
How Expired Wrapped Links Impact Unsubscribes, Compliance, and Long-Tail Campaigns
At first glance, expired email links may seem like a minor technical inconvenience. In reality, this update has wider implications that affect compliance, customer trust, and how teams govern email over time.
1) Compliance risk may be introduced unintentionally
Many spam and privacy regulations require unsubscribe links to remain active for up to six months. If wrapped unsubscribe links in older Salesforce Marketing Cloud emails are no longer functional, organisations may unknowingly fall out of compliance. This is not the result of poor governance, but of platform behaviour changing after emails were already sent.
2) Customer experience can quietly deteriorate
Email is often designed for delayed action. Customers return to messages to access event details, redeem offers, manage preferences, or complete registrations days or weeks later. When a previously trusted email leads to an expired link, confidence in the brand is weakened, even if the cause is technical and unseen.
3) Long-tail email behaviour is often overlooked
Most teams focus optimisation efforts on the first hours or days after a send. Far fewer consider how emails behave weeks or months later. This incident highlights a critical reality: email is not a static artefact. It is a living customer touchpoint that requires ongoing governance.
4) Start with visibility across affected emails
Identify emails sent before 21 January that are still relevant today, especially those containing unsubscribe links, event registrations, offers, or evergreen content that recipients may revisit.
5) Strengthen unsubscribe resilience immediately
Salesforce allows organisations to configure a compliant unsubscribe page and set it as the default redirect within Salesforce Marketing Cloud. Doing so helps maintain regulatory alignment even if older wrapped links expire.
6) Review long-lived campaigns and journeys
If customers are expected to return to an email well after delivery, teams should assess whether alternative access paths or refreshed communications are needed to prevent broken experiences.
7) Reinforce shared ownership across teams
Security updates are becoming more frequent and more impactful. Marketing, technology, and compliance teams must share responsibility for understanding how platform changes affect live customer interactions.
What This Security Update Reveals About Ongoing Email Governance
This situation is not about a broken campaign. It is about a changing operating environment. As platforms like Salesforce continue to strengthen security, the downstream effects increasingly shape marketing execution, compliance posture, and customer trust. The organisations that lead will be those that treat email as an ongoing system, not a one-time output. Resilience, governance, and periodic review are now core capabilities of modern, responsible marketing teams.
