Customer Loyalty and Value Discussion

I need support with this Marketing question so I can learn better. Are you familiar with Dutch Bros Coffee? I would like the post about that. After reviewing the resources on Dunkin Donuts and its marketing across digital channels (social media, websites, email, apps, etc.), choose a brand that you are loyal to and analyze its use of digital platforms, including email marketing, mobile apps, and social media. What platform(s) do you find most effective in reaching you as a consumer? What is least effective? Why do you think this is the case? What impact did that have on your relationship with that business?
