Firstly, privacy laws are not applicable to non-personalised business data.  It is the ‘identifier’ such as a person’s name which is covered by Privacy and SPAM Acts.

It is, however, in your best interest to pacify any person who contacts you to complain!

Simply take their details – as it appeared on the marketing piece they received from you, and mark it in your database so you know not to contact them again.

If you delete the record from your database, when you receive updates or perhaps obtain their details through another channel, you may accidentally contact them again without knowing.

It is therefore important that you ‘suppress’ or flag / mark the details in a field in your database rather then delete them.
