iPost and ZeroBounce Form Email Validation Partnership
iPost, an email sending platform for regulated and data-sensitive industries, announced a strategic partnership with ZeroBounce to embed native, real-time email list verification into the iPost platform. The integration aims to help enterprise customers protect sender reputation, reduce bounce rates, and improve inbox placement by validating addresses at collection and on an ongoing basis. The integration is available immediately as part of iPost’s 2026 product roadmap, which also includes investments in AI-powered content optimization and personalization. To promote adoption, ZeroBounce and iPost offered time-limited discounts on validation credits, subscriptions, implementation, and professional services, and co-hosted a webinar featuring iPost and ZeroBounce marketing leads discussing deliverability and email fundamentals.
