Taking back your Mandrill click-tracking links

My company, like many, has recently switched away from using Mandrill for our transactional email.

We'd been using Mandrill's [click-tracking][mandrill-click-tracking] feature, and became worried about what would happen to all those old emailed links after we cancel our Mandrill account.

Why should we care about links in emails sent a month or more ago?
