AtData has debuted an email list-monitoring tool to help
brands stay out of spam traps and maintain security. 
The new solution, List Guard, protects against toxic emails that can hurt an email marketing program and omnichannel
targeting. 
The goal is to help firms “take the next step in protecting both the integrity of their first-party data and the success of their email marketing program," says Tom
Burke, CEO of AtData.
Burke adds: "We typically see 6% of emails addresses that were originally marked as valid become problematic within the next year, which makes it critical to regularly
monitor your email database." 
AtData’s technology is based on roughly 2 billion monthly email activity signals across its network.

List Guard is an "always-on" solution, identifying email addresses that have become problematic over time, the company claims.
The
new tool also protects against honeypots and dangerous domains, it adds.
