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’).
Alternatively, at least, an eye-catching design. It’s worth letting a proper designer have a go at prettifying your emails. Customers are often opening emails on the go, so you need to work hard to grab their attention. Making your emails nice to look at is a brilliant way to hold their eye. Netflix put time and effort into making their emails stand out, personally and visually – and it pays off for them!
Calculators: A calculator offers customers a lot of value with minimal effort on their part and instant gratification. Even a simple price calculator (e.g., “How much does it cost to buy a house?”) can have impressive results: companies report lead conversion increases of more than 25%, plus a nice boost from social traffic. Offering a calculator as a call-to-action is a sign of your intent to solve a customer’s problem and add value, boosting your brand image for customers who aren’t ready to commit.
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.
Full-funnel campaigns also take into consideration how the marketing funnel has morphed over the years. The old school of thought had a top, middle, and bottom part of a funnel, where customers went in at the top and left it after making a purchase. The funnel has evolved into a customer lifecycle that includes those pre- and post-purchase phases mentioned earlier.
If you're inviting readers to download an ebook, for example, and you have a picture of the ebook included in the email, don't just hyperlink the text next to the image telling people to "download it here." Hyperlink the ebook's picture, too. People are drawn to images much more commonly than text, and you want to give your email subscribers as many options to get your ebook as you can.
