Open and click-through rates (CTRs): Knowing who are engaged customers (those who open most emails and end up making purchases) versus inactive customers (who haven’t opened any emails in months) can be invaluable. Marketing campaigns announcing a new product should absolutely include those engaged customers, while re-engagement campaigns can be created to try and entice the inactive customers.
Building subscriber lists is a common need for email marketers. The important thing to remember with this objective is that your email marketing should be focused on quality and not quantity. Because you could gain an additional 1,000 subscribers but they aren’t really interested in your brand and are therefore not going to add much value to your email database or your business.
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’).
A significant element of email marketing is relationship. Does a recipient trust you? Does a recipient even know who you are? When an email jumps the gun by forcing familiarity too soon, the personalization comes across as skeevy. Intimacy is earned in real life, and it would appear to be the same way with email. Take this example from my inbox; no one has called me lowercase kevan l lee in years.
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.
