Rebrandly links don't expire unless you explicitly set an expiration date or delete them. They will continue to redirect to their URL destinations as long as these conditions are met:
Your Rebrandly account is active. Even if you downgrade to a free account, all your links will continue to function. Deleting your account will delete your links.
You don't send abusive and prohibited content. Rebrandly will not tolerate prohibited content. We will suspend your account and deactivate your links if such content is detected. View our Terms of Use for content limits.
For branded links, your custom domain is active with the DNS pointing to Rebrandly. This means your custom domain registration must be current, and the DNS records must continue pointing to Rebrandly.
