Mission: clean data

Time to go public on a private passion.

Good work is being done to improve direct mail's image in the UK. Royal Mail have launched a 'green' version of postage for their wholesale clients. The Direct Marketing Assocation (DMA) has set up a Direct Marketing Commission to give the public better access to information and services. As part of both of these there is discussion about the correct use of suppression files, and even talk of how to ensure that data is processed correctly before it is used to create mailing campaigns.

However, there is one important part of this that is not yet being addressed. There is huge variation in the quality of data processing itself. It's just not enough to say 'the data has been deduplicated and suppressed'. I've seen the difference between some of the low-cost online deduplications, and the 'proper' kind, and it's huge - it's entirely possible to say you've processed your data, yet still mail thousands of duplicates, people who have opted out, or people who you know to have died.

There's a job to be done to raise the awareness of this, and to get some form of recognition of the importance of the quality of data processing for direct mail. I'm not the only one who believes this, and we're working on how to get it done. I'll write more as this (long-term!) project develops.
