Data Cleansing

According to Ken, Outward Media has productized a database of 300,000,000 email addresses that should never be mailed.

OMI’s Clean-Send Suppression Database can help to protect your email sender reputation and save you valuable marketing dollars.
In a nutshell, OMI Clean-Send is a database consisting of approximately 300 million negative email records (spam traps, foreign IP’s, hard bounces, and other negative email data). Due to the erosive nature of consumer email, we have joined with a consortium of email partners who share the OMI philosophy that data quality is far more important than data quantity.

It’s an interesting idea. I certainly have a lot of clients who have come to me looking for ways to clean old lists and data of unknown provenance. This might be worth looking at.

    Isn’t this contrary to the good habits we are always preaching? If we send *email people want* to an engaged, opted-in group of people who want our mail, why would there ever be a need to clean our lists?
    What am I missing? Am I just being naïve?

    […] all that being said, Justin had a great question in the comments of yesterday’s post about data cleansing. Isn’t this contrary to the good […]
