If you require data lists ofbutchers there are approximately 5,800 across the UK. These are split by Managers and Proprietors to distinguish the independent butchers from the chains. So if you only wanted to market to the independents there is an easy way to filter your mailing list.
Other ways of filtering data lists are by geography or company size. For example the number of employees.
To ensure you source the right marketing data lists it is always best to speak with an industry professional, and at Responsiva you will always get free advice on these matters. Data lists are well priced and counts (such as independent butchers) are supplied without charge or obligation.
There are some two thousand distinct industries to select from and many have different traits as to the best way to identify the right prospect data from within them.
