T-Mobile Email Marketing

All in an email

I designed data-based newsletters to encourage customer engagement and retention for T-Mobile customers.

Each headline and button is tested with T-Mobile's customer database.

Graphics and images are curated from T-Mobile's media library or created using Adobe Suite.

At launch, our team creates variations of our email campaigns to test CTA and headlines. 

These findings are presented to our client during our weekly meeting.

Samsung APP Card Designs

Digital Ads

Working with T-Mobile, I learned how to experiment with multiple constraints and guidelines.

I understood both T-Mobile's voice and their partners, including Apple, Samsung, and T-Mobile Sprint. 

Let's translate

To reach T-Mobile's Spanish-speaking audience, I crafted graphics that could easily be implemented in Spanish. 

Takeaways

Data-Driven Marketing

Working at Zeta Global, I gained knowledge in Big Data, Customer Relationship Management (CRM), and how companies collaborate for campaigns. I learned the importance of design for user engagement rather than aesthetics. Also, it is important to test your designs and have data to support your design choices.

Keep it Dynamic

Throughout the internship, I learned how to design graphics that are responsive to different edits including legal copies and translations. Because we work with large global brands, it is important to consider future changes to designs. This means establishing a strong library of assets that can easily be altered if need be.
