We understand the issues you face

Campaign ROI

Communicating with your customer's through a different channel than they prefer can have a detrimental effect on your campaign ROI and effectiveness, as the chances are - they won't receive your communication.

Brand reputation

If your customers aren't receiving your communications, you risk damage to your customer satisfaction and your brand reputation.


If your contact data is out of date, you risk communicating with the wrong person, and not being able to accurately analyse your data - increasing your risk of a GDPR breach.

How contact appending can help

In an ideal world, you'd have the correct contact details to be able to communicate through your most effective channels, and importantly your customer’s preferred channel. But collecting information from customers and prospects is difficult, even if you have an existing relationship with the individual. Even if you were able to capture all this channel information, it won't be correct forever – meaning you lose communication through preferred channels.

We use a combination of datasets to append your existing contact data, so you can:

  • Quickly and cost effectively increase the information in your database
  • Contact more customers or prospects directly
  • Improve marketing response by using multi-channel campaigns (using three channels is proven to increase campaign return on investment)
  • Save money using the most cost effective and suitable channel for your business and the recipients
  • Gain insight and understanding by analysing your data with greater confidence
  • Target customers with relevant communications, building their trust with the potential to collect more information in the future
  • Improve customer service both on and offline by building a full picture of their interactions with you
  • Boost sales through increased brand awareness
  • Harness social media to improve search engine optimisation and organic search results
  • Increase engagement with your customers by maximising opportunities for customer contact
