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:
Do people who share your view see you as more relatable or trustworthy because of your opinion? Not all opinions or even values make much of a (positive) difference. For example, I could point out that I think people should be treated as equals regardless of their gender or sexuality. Most people who agree with that don’t think much about it. It’s such an obvious thing to them. So, telling that doesn’t make much of a difference to people who agree with me. However, many people who disagree with that might think I’m crazy.
The ideal type of opinion (unrelated to your expertise) is one that doesn’t offend anyone, but makes some people relate to you more. For example, I’m a vegetarian. I used to protest whenever there wasn’t a big piece of meat on my plate. But when I tried eating just veggies for a couple of months, I realized I felt a lot more energetic. Sure, it’s more ecological. And often animals are treated cruelly. But those aren’t the things I emphasize if someone asks why I’m a vegetarian. No one in their right mind has a strong negative reaction to someone eating food that makes them feel energetic, right? But for some vegetarians it’s a very meaningful choice, so it might have a positive impact on those people. That said, I highly doubt that my choice of diet have any direct impact on my sales.

Another type of electronic mailing list is a discussion list, in which any subscriber may post. On a discussion list, a subscriber uses the mailing list to send messages to all the other subscribers, who may answer in similar fashion. Thus, actual discussion and information exchanges can happen. Mailing lists of this type are usually topic-oriented (for example, politics, scientific discussion, health problems, joke contests), and the topic may range from extremely narrow to "whatever you think could interest us". In this they are similar to Usenet newsgroups, another form of discussion group that may have an aversion to off-topic messages.
Anthropologists, sociologists and historians have used mailing lists as fieldwork.[6] Topics include TV series fandom,[7] online culture,[8] or scientific practices[9] among many other academic studies. From the historian's point of view, the issue of the preservation of mailing lists heritage (and Internet fora heritage in general) is essential. Not only the text of the corpus of messages has yet to be perennially archived, but also their related metadata, timestamps, headers that define topics, etc. Mailing lists archives are a unique opportunity for historians to explore interactions, debates, even tensions that reveal a lot about communities.[10]

Don’t talk down to people. I think this should be obvious. But looking at the email offers I get, clearly it isn’t. Don’t tell people, “Not buying this product would be idiotic!” or “Only a fool doesn’t understand the value in this service.” This whole email marketing strategy relies on you making people understand the value they can get from you. And sometimes that means making people see the downsides of not buying. But you can do that in a friendly, respectful way.
Whether you already have a list of subscribers or are starting from scratch, email marketing services can help. All of the services we cover let you add contacts manually using copy and paste or by uploading CSV or Microsoft Excel files. Some integrate with third-party software enabling you to import Gmail and other webmail contacts, Salesforce and other CRM data, or other software where you might have contacts stored. Depending on the size and location of your list, third-party integration could be key. Verify whether you can export contacts as well (and how easy it is to do so) should you leave the service. Managing users who unsubscribe should also be easy so you're not accidentally contacting anyone who has opted out of your newsletters.
High reach: When people join your email list (subscribe or “opt in”), you can reach them. If they just like your Facebook page, for example, it’s unlikely that they’d see many of your updates. Sure, not everyone opens your emails, but the numbers are heavily in favor of email marketing compared to other similar marketing tactics. I’d rather get 1,000 new email subscribers than 10,000 Twitter followers.

Surprise: Customer loyalty is the key to success. And you can reward your loyal customers by giving them something for free every now and then. Create a “surprise” email that sends an automated email to your best customers that offers a free yearly license to your software for them to use, a gift card or even a coupon code to redeem a box of cupcakes. It’s a small cost for your business but, the reward is huge!
