What Works Really Well in Starbucks’ Email

  • Bold, Clear Offer Front and Center
    The headline says it all: “GET 50% OFF YOUR DRINK”. It’s impossible to miss and immediately communicates the value. Discounts are magnetic—start with value, and you hook your reader.
  • App-Exclusive Focus
    Starbucks cleverly reminds readers that this deal is available in their app with phrases like “GET THE BEST OF EVERYTHING IN THE APP” and “APP-Y DAYS.” This not only drives app downloads but also builds long-term loyalty.
  • Creates Urgency with Timing
    The offer is only valid Fridays, all May, 12-6 PM. This limited window motivates readers to act fast—fear of missing out is a powerful driver.
  • Eye-Catching Design
    The bright, summery colors and refreshing drink images evoke positive emotions, making readers want to treat themselves.
  • Friendly, Clear Call-to-Action (CTA)
    The button reads “See you Friday!” which feels warm and inviting, lowering barriers to click-through.
  • Simple Instructions
    Starbucks clearly explains how to redeem the offer—“Your coupon will be in the app. Apply it at checkout or ask your barista.” No confusion, no excuses.
  • Brand Consistency and Trust
    The email uses familiar Starbucks colors, fonts, and logos, along with visible contact info and legal disclaimers. This builds trust and professionalism.

Why This Email Works

  • Value First: Readers instantly see what’s in it for them—a big discount on a product they love.
  • Emotional Connection: Phrases like “Kick off the long weekend” and “try something summery” create a positive mood and associate the brand with good feelings.
  • Easy to Scan: The layout is clean and uses a clear visual hierarchy that guides the reader effortlessly.
  • Exclusivity: Linking the offer to the Starbucks Rewards app makes customers feel like insiders, encouraging loyalty.

How Starbucks Crafted This Email

  • Typography and Emphasis: Bold fonts highlight key words and phrases, focusing attention exactly where it matters.
  • Urgency Is Upfront: The limited-time offer details are near the top, encouraging immediate action.
  • Balanced Visuals: The use of bright colors and appealing images balances sales messaging with warmth.
  • Transparent Footer: Terms and conditions are clear but unobtrusive, building credibility.

What Could Be Even Better

  • Stronger CTA: “See you Friday!” is friendly but not very action-oriented. Something like “Claim Your 50% Off Now” might drive more clicks.
  • Highlight Exclusivity More: Adding a line such as “Exclusive offer for Starbucks Rewards members” would increase perceived value and push sign-ups.
  • Promote App Downloads: Including a clear download link or icon for the app could boost participation from new users.
  • Add Social Proof: A quick testimonial or star rating on the featured drinks could build curiosity and trust.
  • Add a Secondary CTA: A button like “Order Now” or “See More Deals” could capture readers ready to act immediately or explore other offers.

And that’s a wrap for this edition!
