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.
While email is the most mature (that sounds better than “old,” right?) form of digital marketing, there’s no shortage of marketing technology innovation in this area. Both startups and established vendors continue to develop new capabilities for formatting, targeting, sending, and monitoring the impact of email messages, as well as functions like list building, inbox management, video email, deliverability, branding, custom email signatures and more.
