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.
Ideally, email marketing should go hand in hand with social media. Adding social media "Like" or "Share" buttons to your marketing emails gives an additional way for customers to connect with your brand. Snippets of positive reviews from social media fans can be included in emails, and conversely, social media postings can be used to encourage fans to subscribe to your email newsletters.
