We collaborated with Blenheim Palace to create a premium B2B database. We identified and secured 48,109 personal contacts for Blenheim to use in marketing their space hire services. All 48,109 contacts were Senior decision-makers in PA, Event Planning, and Corporate Events. All were located within a two-hour drive of Blenheim, including London. Each contact record included the contact’s name, company name, complete address details, telephone number, contact details, and personal B2B email addresses directly to the individual. With no generic details such as info@ or hello@.

Blenheim’s Objectives
The main goal for Blenheim Palace was to find senior decision-makers who were in charge of their companies’ planning of corporate events, conferences and other professional gatherings and market their renting location space to them. They set out to find the top names in the event planning industry and reach out to them by leveraging our B2B data for a targeted email campaign that would showcase Blenheim Palace as an excellent option for a corporate events venue. Their goal was to pull in contacts within a two-hour drive of their address; they also wanted to include London in their targeted reach. Their ultimate goal was to produce quality leads that could drive more bookings and inquiries for their event spaces.
How Blenheim Palace Experienced True Success
Here at Business Data Prospects, we used the following key solutions to help Blenheim Palace achieve their objectives:
- Advanced Data Preparation: We prepared a targeted data selection from our continuously maintained business database, refining the records to match Blenheim Palace’s campaign requirements.
- Targeted Data Selection: We selected senior decision-makers responsible for PA, event planning and corporate events, applying geographic filters to cover the required radius and key London locations.
- Quality Checks: Every record underwent our quality assurance process to improve accuracy and remove outdated or irrelevant information before the completed data order was delivered.
- Personalised Contact Information: Wherever available, the data included named decision-makers and direct business email addresses, helping Blenheim Palace communicate with the right people rather than generic departmental inboxes.
- Ongoing Account Management: Our team remained available throughout the project to answer questions and provide support, helping the campaign run smoothly from planning through to delivery.
The True Value of Good Quality Data
In return for this, the creation of a specific and high-value dataset saw Blenheim Palace benefit in a number of ways:
More effective targeting: Business Data Prospects supplied a targeted selection of senior decision-makers from its in-house business database. Every selected record was individually reviewed, updated and verified before supply, helping Blenheim Palace focus its marketing spend on businesses with a genuine interest in event planning.
More Engagement: With detailed contact information, Blenheim Palace created more relevant and engaging email campaigns. This level of personalisation increased their email open rates and response rates by making the content more relevant to each recipient, which sparked more interest from potential clients.
Increased Scale: The dataset covering local & London geographical areas resulted in Blenheim Palace seeing broadened outreach and clientele. Which in turn led to more eyes and therefore potential bookings.

About Blenheim Palace
Blenheim Palace (which is world heritage listed) – one of the most beautiful historic estates there is. This Baroque palace is a crowd favourite and attracts thousands of visitors each year to walk through its stunning gardens and historic halls. Blenheim Palace also stands as a noteworthy event space outside of its cultural significance. Corporate functions, private events, and public shows.
Blenheim Palace has been looking to boost the venue’s event-hosting capacity in recent years, aiming to bring in more corporate customers as well as increasing its profile within the event-planning sector.
How they did it: They needed to get in front of the people who would be interested in hosting events at such a prestigious venue. Consequently, they reached out for specific data we provided them to carry out a successful email marketing campaign targeting the right professionals in the right sectors.
About Business Data Prospects
Our goal at Business Data Prospects is to provide customised B2B datasets that suit the unique goals of our clients. For examples of how we’ve helped other organisations, including Blenheim Palace, see Business Data Prospects clients page. To fulfil their specific requirements, we did the following:
Getting to know the requirements: We held multiple conversations with Blenheim Palace to understand their audience and data needs. That included identifying key industries, relevant decision-makers and geographical parameters.
Data Curation and Compilation: We collected contacts that suited the specific criteria for Blenheim Palace, targeting senior decision-makers in the corporate events industry. We made the data comprehensive, credible, and current.
Tactical Local and Role-Based Filtering: The list was strategically refined to identify contacts located within a two-hour drive of Blenheim Palace. We also added London to reach a primary metropolitan area with great corporate event potential.
Adding Data Quality Assurance: In order to be able to get the most out of Blenheim Palace’s email campaigns, we provided as much detailed contact information as possible – personal names, company names, full addresses, phone numbers and direct email addresses. This meant not including generic emails avoiding those contacts and as such we made sure our database is not filled with the usual stuff everyone lost interest long ago, those that wont actually do the job.
Delivery & Support: Upon completing the dataset, we delivered in a user-friendly format and provided post-delivery support to help Blenheim Palace incorporate the data into their email marketing platform. We were available to answer any questions, and we guided a seamless implementation.
