An example here is the rapidly growing trend of "inbox zero." It's actually known by a variety of names, but it refers to the practice of keeping your email inbox count at zero stored emails. Essentially, it's dealing with every email as it comes in and then deleting or archiving each one so that your inbox is always empty. This boils down to a fundamental shift in how users are utilizing their email inboxes.
As new marketing techniques and strategies pop up almost daily, email marketing has truly evolved to keep pace with flashy new technology and capture the attention of customers. A great email helps you engage your customer and deliver your message, which can make a difference between a click-through and a direct route to your website or losing a customer’s interest and being sent to the spam folder.  Modern marketers need a combination of eye-catching design, clever text, and attention-grabbing headlines to engage today’s consumers. That’s why we have compiled a collection of our favorite emails.

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:
Obviously, it takes more work to create and place guest posts, but it’s worth it if the publication is aligned and authoritative. We found a way to create additional value with this as well by working with internal HubSpot experts who wanted to get their thoughts out on a given subject. For example, here’s a guest post that Blake Toder wrote for the Usabilla blog:

One of the first questions new (and even experienced) marketers often ask is: “What’s the best autoresponder service or email marketing tool?”  Autoresponders and email marketing tools are some of the most important parts of your business. You use it to follow-up with customers. To keep people coming back to your site. To build loyalty. To make sales. Yet the answer is often not so clear cut. Do you want the highest deliverability possible? Do you want to import offline contacts? Do you want to integrate your list management with a shopping cart? Do you want to spend $20 a month or $500 a month? The answer to these questions all yield very different answers. Here are the top 10 autoresponder tools on the market, along with who they’re for and what they’re capable of.
Your goals and objectives need to be different for whether it's an eblast (promotional email) or regular enewsletter. Eblasts are great for getting quick leads/sales, while enewsletters are better for staying top of mind, educating customers on new offerings, or providing helpful industry updates. I have found them to be very successful, but what works and what doesn't requires testing (of both the subject line and creative) and varies per business. Best practices for both types include have...
Yahoo Mail takes extra steps to keep your account secure by automatically enabling spam filters and directing messages into the spam folder. It also recognizes some junk mail and will place these items in the trash bin rather than your primary inbox. Another positive feature our testers liked is the sender block, which lets you add an email address to a black list. Rather than redirecting emails from these senders into the spam or trash folders as other email services do, Yahoo Mail blocks these messages entirely.
It's important to choose an online marketing service that has a clean and intuitive interface so it's easy to find the tools you need. A well-designed platform means you won't waste time trying to find the solution or the support you need. You'll also want the service to have an easy-to-use email editor, contact management tools, and drag-and-drop automation tools. 
Things are probably more complicated than that, though. As a recent survey conducted by market research firm Statista clearly shows, email is one of the most popular apps for mobile devices across most organizations and even consumers. Given how many workflows, business processes, and just plain important communications take place over email, this is one area where you likely shouldn't skimp.
