The Backstory

Boston Globe Media saw a clear shift: Gen Z wasn’t consuming local news through newspapers, TV, or traditional websites. Rather than forcing old formats onto younger readers, the team pitched a new product—a creator-led, email-first news brand built specifically for how Gen Z consumes content.

The idea for The B-Side came out of a company-wide hack day and was greenlit as an internal startup.

Why a Newsletter

Email offered what social and web couldn’t:

• A direct, one-to-one connection with readers
• A consistent daily habit
• Ownership of the audience, independent of algorithms

The goal wasn’t just reach—it was daily engagement.

Why beehiiv

Before beehiiv, Boston Globe Media primarily used Mailchimp. For The B-Side, they needed something different.

beehiiv stood out because it allowed the team to:

• Launch a self-contained media business from zero
• Access deep analytics without an analytics team
• Build a distinct brand separate from Boston Globe Media
• Scale without pricing penalties

Andrew described beehiiv as differentiated enough to justify breaking from existing tooling.

Growth Strategy

The team avoided blasting the newsletter to existing Boston Globe lists (which skew older). Instead, they focused on high-intent, on-brand acquisition:

• Targeted placements on Boston.com (food, culture, events)
• University partnerships (BU, Northeastern)
• Giveaways and local brand collaborations
• Event-based signups with partners like Sofar Sounds
• Strong social presence via short-form video

Growth was intentional, slow, and audience-first.

Monetization

Current:

• Native newsletter ads written in The B-Side’s voice
• Premium placements amplified across Boston.com

Planned:

• beehiiv Ad Network
• Live events for 20–30-year-olds in Boston
• Membership (guides, events, exclusive access)

Results

After 5 months on beehiiv:

• 10,000 subscribers
• ~60% open rates (daily send)
• 8–10% click-through rates
• Strong deliverability and platform reliability

Andrew emphasized quality over vanity metrics, noting the audience was “hyper-engaged.”
