I echo the concerns of some other customers above. We have some emails where this won't affect much, but we have some other emails whereby we'd like the links to stay active for longer than 90 days.
Question for an employee: If we go back into a current email (say in our engagement/nurturing program), can I update all links, save the draft, and it'll now have the short URL? I'd hate to see this mess up the 9 emails already in our nurture/engagement stream. Thanks!
