PowerDMARC

What is PowerDMARC?
PowerDMARC monitors and enforces DMARC, SPF, DKIM, MTA-STS, and BIMI records from a cloud dashboard. Teams publish authentication policies, review aggregate and forensic reports, and move domains from p=none toward quarantine or reject to block spoofing and phishing. The platform also ships free public checkers for DMARC, SPF, DKIM, and BIMI lookups.
Generic email security suites spread across many products. PowerDMARC centers on authentication enforcement with hosted SPF flattening, one-click DNS publishing, a live threat map, and an in-dashboard DMARC AI Agent for troubleshooting SPF permerrors and deliverability drops. MSP and MSSP partners get a white-label multi-tenant console to resell under their own brand.
IT admins, MSPs, and marketing teams at mid-size and enterprise organizations use PowerDMARC to meet Google and Yahoo sender requirements, protect domain reputation, and monitor blacklist and header health. Pricing starts with a free personal-domain tier and scales to custom enterprise quotes.
Opnbx.ai

What is Opnbx.ai?
Opnbx.ai is a B2B sales intelligence platform built around what the company calls Precision Prospecting. It gives sales and marketing teams a unified data layer to spot which accounts in their market are worth pursuing right now. The product focuses on ICP validation, intelligent segmentation, and account-level research rather than generic firmographic lists. Teams log in through app.opnbx.ai after booking a demo through the marketing site.
Most intent data vendors sell broad market signals that every competitor can buy. Opnbx.ai tries to correlate signals from your own closed-won deals with live account activity, then scores and prioritizes companies against that custom model. The homepage positions it as a replacement for stitching together a Franken-Stack of tools like 6sense, Clay, Bombora, and ZoomInfo. That trade-off is narrower fit modeling in one platform instead of buying the same commoditized feeds everyone else has.
It targets sales leaders, RevOps teams, and individual reps at B2B companies running outbound or pipeline development motions. Integrations listed on the site include Outreach, HubSpot, Salesforce, Salesloft, and Apollo.io. Customer testimonials on the homepage come from teams at Datavolo, Vial, Descope, and Pangia who cite faster account research and higher conversion rates after onboarding.
