Keeping an in-house database “clean” is such a dull job that it can hang around at the bottom of the to-do list permanently. In 10 signs your in-house database needs help BEFORE you launch another program, the B2B Lead Blog lists the sort of problems lurking in most databases. I’m sure many of you will recognise more than one of them.
In the comments, there’s a reference to a claim made last year that clean data can scale up to huge gains in revenue. I’m sure it’s true. And one more thing: if you’re sitting on a database of addresses and telephone numbers with lots of missing emails, isn’t it time you created something great (and emailable) so you can contact these people and get their email addresses in return for it?
