Business Groups	Business Size
By business description	A limited breakdown into small medium and large companies but information on the number of employees is not available
By SIC codes

As well as using any of the above criteria to select companies the criteria may also
be used to exclude companies.

Previously Faxed Companies

A detailed record is maintained of all the companies faxed for a client and the date the faxing was carried out. Clients are therefore able to request that companies previously faxed may be excluded from a new fax run or specifically selected for a new fax run.

New companies are regularly being added to the Central Messaging databases and a client may wish to select companies which meet their criteria but which they have not previously faxed.
