InboxSeguro Platform

InboxSeguro gives companies visibility and control over every system that sends email using their domain. It builds an inventory of sending systems from DMARC reports (detected via PTR/ASN and DKIM), where you can assign an owner and a status (approved, inactive, review) to each one. It alerts when a new sender appears, when volume falls outside the expected monthly range, or when SPF/DKIM failures suggest a possible spoofing attempt. It also detects forwarding, monitors DNS status, and checks the domain hourly against 6 major spam blacklists (such as Spamcop and Barracuda), with guidance to request removal if listed. Guided DNS setup with an AI assistant helps move safely from p=none to quarantine or reject. Each month it generates a technical report and a governance PDF that supports internal reviews and audits. Built for B2B, e-commerce and SaaS companies in Latin America, with setup in Spanish.
