One of the best ways to engage email subscribers is to connect with them emotionally, although this is often easier said than done. I have spoken and written many times about the importance of creating emotional resonance – either positive or negative – between your message and your audience. It's essential because without some sort of feeling connection to you, at least occasionally, subscribers will become bored by the purely practical often repetitive litany of subject lines cropping up in their inboxes (i.e. 20% savings this week!) and easily tune out.
