Do people who share your view see you as more relatable or trustworthy because of your opinion? Not all opinions or even values make much of a (positive) difference. For example, I could point out that I think people should be treated as equals regardless of their gender or sexuality. Most people who agree with that don’t think much about it. It’s such an obvious thing to them. So, telling that doesn’t make much of a difference to people who agree with me. However, many people who disagree with that might think I’m crazy.
We also love how consistent the design of Uber's emails is with its brand. Like its app, website, social media photos, and other parts of the visual branding, the emails are represented by bright colors and geometric patterns. All of its communications and marketing assets tell the brand's story -- and brand consistency is one tactic Uber's nailed in order to gain brand loyalty.
The primary cost of poorly crafted or mis-targeted emails is lost business opportunities, though in extreme cases it can damage a firm’s reputation as well. But the potential payoff for effective email marketing is substantial; email messages are more likely to be seen and acted upon by decision makers than online content, social media, or advertising.
