Are you willing to alienate people who disagree with your opinion? Sure, not everyone who disagrees with you will unsubscribe. But if you can’t take the risk of alienating a large portion of them, it’s better to avoid the topic. The only exception are friendly disagreements. For example, it can be a good idea to show your support for a specific sport team, even if you know many in your audience like another team. As long as they don’t take the sport very seriously, it can be just a fun thing to talk about. I could, for example, tell that I’m more of a dog person (we have two dogs) than a cat person. I have nothing against cats, but I like walking with dogs. I doubt almost any cat person will hold that against me.
The subject line should link seamlessly to your main headline and then to the lead copy and into the body of the email. Ensure that the subject line is relevant to the content and incites a relevant expectation – clickbait is bad, folks! Open rates are not the only metrics by which to measure success (I’ve heard it said that open rates are ‘vanity’ and clickthroughs are ‘sanity’).
The terms ‘aim' and ‘objective' are often used interchangeably. However, they are not the same. Aims are an overarching end goal (and are usually specific). Objectives are steps along the road to that goal (and can be a bit more flexible). Aims are long-term outcomes, while objectives are short-term targets. Different objectives work towards different purposes. For example:
Purchase (formerly the bottom): This phase should drive the sale, such as a free trial or discount offer. These messages can be much more direct and sales-oriented since these customers have indicated they are closer to a purchase than others. In this phase, it’s important to keep your emails focused on the primary call to action (CTA) and make sure the transaction is as easy as possible. Some companies opt to offer post-purchase set-up assistance or support to help customers move from engagement to purchase.
Everyone's busy and their inbox is already full. Why add to the problem with a longwinded email? People generally like short, concise emails better than long ones because concise emails have an obvious focus. Plus, when your users are scanning through all their emails in a short amount of time, they're more likely to find the overall message before deciding to take any action.
