First of all, BuzzFeed has awesome subject lines and preview text. They are always short and punchy -- which fits in perfectly with the rest of BuzzFeed's content. I especially love how the preview text will accompany the subject line. For example, if the subject line is a question, the preview text is the answer. Or if the subject line is a command (like the one below), the preview text seems like the next logical thought right after it:
InfusionSoft is the tool of choice for serious marketers. If you run a six figure online business or have a list larger 50,000 subscribers, this may be the tool for you. InfusionSoft combines your shopping cart with email marketing, so you can do complex things like segregate your buyers from your subscribers or mail specific sequences to specific people. You can also send physical postcards from InfusionSoft. InfusionSoft isn’t cheap. The monthly subscription is in the hundreds, and there’s a four figure setup fee. It’s geared towards companies that are already successful and need powerful solutions, rather than startups.
A lead magnet (a.k.a. an optin bribe) is something amazing that you give away for free in exchange for an email address. This doesn’t have to cost you anything to create; most lead magnets are digital materials like PDFs, MP3 audio files, or videos that you can create yourself at minimal or no cost. It can be absolutely anything you want, so long as it provides value to your visitors for free.
