Declining email engagement in a crowded digital landscape

Despite having a healthy-sized email list, Napiers was seeing the usual suspects when it came to challenges:

  • Open rates were flatlining
  • Click-throughs were dropping
  • Audiences were disengaged and simply not responding to promotional content the way they used to

The team knew that to reignite engagement, they needed a channel that was more immediate, personal, and friction-free.

Meet customers where they already are

Rather than pushing harder on email, Napiers took a bold step: they introduced WhatsApp as a primary marketing and communication channel.

Here’s what the strategy looked like:

1.  WhatsApp Call-to-Action on Website‍

Visitors were invited to subscribe to exclusive offers via WhatsApp. The message was simple: “Get VIP deals, straight to your phone.”

2.  Value Exchange

In return for sharing basic data - like birthday and shopping preferences, users received exclusive discount vouchers and early access to promotions.

3.  Ongoing Campaigns via WhatsApp

Once subscribed, customers received timely, personalised messages through WhatsApp. These weren’t spammy blasts - they were curated updates, birthday offers, and tailored product promotions that felt useful, not intrusive.

Why it worked: The WhatsApp Advantage

The shift to WhatsApp as a primary marketing channel proved successful for several key reasons:

- High visibility: WhatsApp messages are nearly impossible to ignore - unlike emails that get lost in cluttered inboxes.
‍

- Direct and personal connection: The conversational nature of WhatsApp creates an intimate connection that feels more like a one-to-one interaction than a broadcast.
‍

- Frictionless UX: Signing up was easy, and the rewards were instant.
