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:
Electronic mailing list servers may be set to forward messages to subscribers of a particular mailing list either individually as they are received by the list server, or in digest form in which all messages received on a particular day by the list server are combined into one email that is sent once per day to subscribers. Some mailing lists allow individual subscribers to decide how they prefer to receive messages from the list server (individual or digest).
Sample review: “See what happens to your emails after you press send…you’ll know exactly when they opened your email and whether or not they clicked on your link. BananaTag will even tell you whether they’re on their desktop or mobile device. And best of all, your email appears NO different to your contacts. All of the tracking is done seamlessly without any change in the user experience.” — BuzzBlogger
You can also voice opinions that repel people you don’t want to work with. For example, I’ve shared that I don’t like working with people who don’t take responsibility for their own life. If someone’s more likely to blame outside factors for their misfortunes than look for things they could do to change the situation, I won’t have a good time working with them.
A tracking pixel is a snippet of code that allows you to track your subscribers’ activity across various channels like your website, landing pages, and newsletters. Then, you also have the option to send emails triggered by certain behaviors. So for example, if a subscriber goes to your site and checks out your product page, a tracking pixel can send an email with a special offer for the specific product the viewed.
