This is a generic and more formal introduction that you can use for jobs with less creative leeway. Of course, it's not as attention-grabbing, but it may work better with more traditional companies.
"I am currently a senior at Northwestern University's Medill School of Journalism seeking the position of an editorial assistant with POPSUGAR. I am looking for a creative work environment, one where I can indulge in my passion for celebrity news and utilize my new media background."
Start out with a compliment. Remember, you don't want to go overboard with this and sound like you're fawning. Make it fun and attention-grabbing.
"Before I say anything, I'd like to thank POPSUGAR for creating such insanely addictive and comprehensive content that has become my go-to daily reading material — my bookmarks folder is ever grateful for the breathing space."
Start by talking about your job experience. It's your chance to bring attention to the most impressive part of your résumé.
"Two years of serving as the editor in chief of the biggest fashion magazine on campus has made me even more passionate about covering and being the first to spot the latest trends."
Show how well you know the company. In the example below, I address the heart of what POPSUGAR is about and what really sets it apart from other media companies. It shows that I'm really paying attention to the brand.
"There aren't any media companies like POPSUGAR — I truly admire the way POPSUGAR has its finger on the pulse of the latest and greatest happenings yet always manages to cover them in a tasteful way."
Cite your skills to show why you're a good candidate.
"As someone who obsesses about the celebrity world, loves the rush of being the first to break news, and uses the virality of social media, I will make a great addition to the POPSUGAR team in San Francisco."
Start with an eye-catching intro that doesn't make it immediately obvious that you're writing a cover letter. This hooks a reader into the story, especially someone who has been reading cover letters all day. I added in specific examples toward the end that will definitely impress the hiring manager. It's always better to throw in examples rather than be vague, because it's more impressive and makes you look more legitimate. It's also always a good idea to tack in well-known names and brands if you have them.
