Onboard Users Smarter

Automate your current vetting process and make informed onboarding decisions with a granular view into a user's email data. We provide an overall score for each list, as well as historical deliverability data for each email address on the list.

Our comprehensive email data goes beyond just identifying if an email address is valid. Emails are given a grade of A+ to F based on the historical deliverability and engagement of the address, and are then analyzed daily for new information.

Committed to empowering good senders

In 2012, we became aware of unaddressed needs in the email marketing industry. We didn't know what was wrong, but we knew something wasn't right. Email validation, list cleaning, and the email hygiene industry was broken. We founded with the belief that there should be a comprehensive and ongoing solution to deliverability and compliance issues that's self service, priced fairly, customer centric, and integrated with your current email tools.

In Fall of 2013, acquired and launched Email Assurance, the next generation of email deliverability and compliance. We will continue to push the envelope in terms of the value we deliver and set the industry standard for email marketing deliverability and compliance. Our team is the right mix of smart, creative, and crazy to continue innovating the email compliance industry.
