We’ve been using the Selectabase consumer list builder tool to profile and order highly targeted households for our direct mail campaigns, and it’s been a real asset to our business.
The list builder is easy to use, with a huge range of selection criteria that allows us to build accurate, relevant audiences for very specific client requirements. As a mailing house, having this level of control is essential to reducing wastage and maximising campaign performance.
Data accuracy has been excellent, and we’ve seen consistently strong results from the mailings we’ve run using Selectabase data. The team are also very knowledgeable and supportive, which makes the whole process straightforward from start to finish.
If you’re looking for a reliable data partner for targeted direct mail campaigns, we wouldn’t hesitate to recommend Selectabase.

Great company and excellent customer service. We’ve worked with similar businesses before, but with Selectabase we were up and running within just 24 hours of our enquiry. This even included a 1-2-1 session with Iona, who guided us through how to get started.
Iona has been knowledgeable, quick to respond to queries, and happy to jump on a call to share advice on how to get the best out of the data.
A big thank you to Iona and the whole Selectabase team!

As the owner of Redhouse Telemarketing since 2013 I'd never had to use a data broker service as most of my clients purchased their own data & believe you me I've worked with plenty of bad & out of date data!!
In Oct of 2023 one of my clients received a mailing from Selectabase offering a free sample of data to trial 25 prospects, we had nothing to lose, from the start of my dealings with Selectabase I was impressed with their professionalism & they clearly understood the reasons why it's imperative to get data correct when marketing particularly telemarketing.
After we'd selected our chosen criteria's in terms of turnover, number of employees, sectors to target & area the rest was plain sailing, I dealt with Iona who held my hand all the way through, even when I needed a "top up" & had forgotten the system (all typed out step by step now!!)
I found the data to be accurate, with correct contact numbers & names, all this is great but the reason we needed new data was to create more leads & meetings, thus more new clients, our first batch has resulted in 5 meetings, 3 of which turned into business, hence we've just re-ordered more data, we have definitely seen a return on our investment.
If you are still unsure I would recommend an informal chat with Iona at Selectabase, I wouldn't go anywhere else.
