Validity Engage
What Validity Engage is
Validity Engage helps teams identify email deliverability problems through placement testing, reputation monitoring, authentication checks, and pre-send risk reviews. Placement reports show where messages land by provider, IP, and domain, covering more than 90 email providers. The service tracks Sender Score across IPs and domains around the clock and can alert teams to reputation drops. It monitors authentication configuration and alignment and notifies users when IPs or domains appear on blocklists. Before sending, a deliverability check surfaces spam-trap, reputation, and authentication risks. Engage also combines email creation, testing, deliverability, and contact data quality. Listed integrations include MCP, Slack, Teams, and Salesforce contact-record deduplication and reconciliation. It is offered on the web and through an API for select qualified customers where supported. Validity presents it for enterprise-scale organizations. Pricing is custom by quote, with some capabilities requiring subscriptions or Engage Credits.
