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.
