Make it easy to subscribe. Post a signup form on your homepage, blog, Facebook page, and wherever else your customers and fans are already active. You might want to collect names and birthdays (for a special offer or gift) or invite readers to join groups, but don't go crazy with the required fields. A too-long subscribe form might scare people off.
Remember, data collection is a two-way street. People won't give you their data for anything. So, think about how you are managing your subscribers' expectations. How clear is it to new recipient what they are going to be receiving from you? Try and get a good a feel for the experience of the person receiving your data collection methods as you can at this point.
Email design matters in any successful email marketing campaign. If your emails look terrible, that reflects badly on you, and can make people stop reading. With more people than ever reading emails on mobile devices, it’s important to use a responsive email template so your email resizes automatically whether people are reading it on a phone, tablet, or desktop.
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!
