5 years ago when I was applying to lots of agencies I sent out custom links to each one. So when they landed on the site, their company name was used in big letters at the top of the page ("Hi company X"). It also allows for tracking whether they actually look at your site. It's easy to do, shows that you're not just spamming people, and is not as involved as some of those more intense examples that target one specific company.
