Considered. Precise. Ever-Improving.

Segmentation and testing are the quiet engines behind high-performing email.

At Westbury Studio, we take a thoughtful approach - building audiences that reflect your customer base, then refining the message through careful experimentation.

This isn’t guesswork. It’s strategy, backed by data and led by an understanding of who your customers really are.

Whether you’re a longstanding British brand or a rural startup with growing reach, this service ensures every email is sent with clarity, intention, and impact.

What’s Included

• Thoughtful Customer Segmentation
  We build dynamic audiences based on real behaviours - such as past purchases, lifetime value, location, and level of engagement.

• Strategic A/B Testing
  Every test has a purpose. From subject lines to creative layouts, we refine what works and quietly retire what doesn’t.

• Send Time Optimisation
  We analyse when your customers are most likely to engage - and schedule accordingly.

• Engagement Tiering
  We separate active, passive, and lapsed customers, tailoring your messages to suit each stage of the customer lifecycle.

• Subscriber Health & List Hygiene
  Your list is your asset. We monitor it closely - suppressing disengaged contacts and maintaining long-term deliverability.
