Protect your data with 24/7 monitoring

Up to 6% of good email addresses turn toxic each year, it only takes one to sink your entire email program. We can help you stay vigilant by constantly scanning your list and alerting you when deliverability threats arise.

Email addresses “flip” from good to bad when:

remove toxic emails

They get recycled as a spamtrap

Improve single view

A recipient registers on the “Do Not Email” list

Questions

A recipient becomes a frequent complainer

social media reach

A mail exchange domain is retired

AtData’s List Guard™ provides “always on” protection to keep your list clean.
