Validity Everest

Validity Everest provides email senders with complete visibility and control over deliverability. The platform validates email addresses before sending using BriteVerify technology, identifying valid, invalid, and risky addresses to reduce bounce rates and protect sender reputation. Everest monitors sender reputation across mailbox providers, keeping teams aware of blocklist issues and spam trap risks. Features include authentication tracking (SPF, DKIM, DMARC), encryption status (TLS), reputation dashboards showing metrics beyond what ESPs display, and alert systems for deliverability issues. The platform was formed by merging Validity's Return Path and 250ok acquisitions into a single unified platform. Everest is now part of Litmus from Validity, allowing teams to build, optimize, monitor, and analyze email campaigns from one integrated system.
