Definition
Email link expiration management defines how long links within emails remain active before they stop working. Expiration is common for security-sensitive links such as password resets, magic links, one-time offers, account verification emails, and time-limited promotions. The expiration period must balance security — shorter windows reduce the window for unauthorised access — against subscriber convenience — longer windows accommodate subscribers who do not check email immediately.
Link Types and Typical Expiry
- Password reset links: 15-60 minutes
- Magic link authentication: 15-30 minutes
- Account verification links: 24-72 hours
- Time-limited promotional offers: 24 hours to 7 days
- Double opt-in confirmation links: 48 hours to 30 days
- Download links: 24 hours to 7 days
Best Practices
- Set expiration based on the sensitivity of the action and the typical user response time
- Communicate expiration clearly in the email so subscribers know the window
- Provide a mechanism to request a new link after expiration rather than leaving subscribers stranded
- Test expired link flows to ensure the error experience is helpful, not frustrating
- Log link expiration events to identify subscribers who regularly miss the window
