Well done to Simon and the Team.
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.
