Newmarket Holidays

Goal:

Grow their current CRM database with quality leads which convert to sales. In addition, we ran a dual channel campaign, targeting individuals by email and postal, encouraging them to book and save 15%.

Solution & Targeting:

We created a competition which encouraged people to sign up to win a £5k holiday. Taking their key audience demographics, we targeted wealthy retirees/empty nesters with the competition, these were the type of people who generally book via Newmarket. We targeted each recipient twice, with the second email being a nudge.

Insights

  • The audience who signed up to Newmarket via the competition, converted quicker than their average consumer to a sale.

  • Over 65s were the most lucrative audience.

  • For the dual postal and email campaign, we used two control segments, one receiving only postal and one receiving only email. The email only campaign produced the best ROI.
