Features and specs

What each product offers, as listed by its team.

PowerDMARC 5 features
ShellNewHandler 0 features
  • Email Authentication Suite
    PowerDMARC offers a wide range of email authentication protocols including DMARC, SPF, DKIM, MTA-STS, TLS-RPT, and BIMI, providing a holistic approach to email security and brand protection.
  • MCP Server Integration
    Connect Claude, Cursor, ChatGPT and other MCP-compatible AI assistants to your PowerDMARC account through a hosted MCP server. You can query DMARC reports, check domain health, look up DNS records, and manage domains and hosted records in plain English, all secured with your own API key permissions.
  • Email Deliverability
    Test where your emails land (inbox, spam, promotions or blocked) across Gmail, Outlook, Yahoo, iCloud, Zoho and AWS. Each test also validates SPF, DKIM and DMARC and gives a prioritized list of fixes. Reputation and blocklist monitoring alert you as soon as your sending reputation starts to drop.
  • AI Threat Intelligence
    PowerDMARC includes advanced threat intelligence features that help organizations detect and prevent phishing and spoofing attacks, enhancing the overall security posture of an organization.
  • DNS Security Compliance
    Daily automated checks score each domain from 0 to 100 (graded A to F). The checks cover DNSSEC, CAA records, dangling CNAMEs, nameserver health, SSL/TLS certificates and domain transfer locks, and come with step-by-step fixes. Checks are mapped to NIST SP 800-81r3, and the exportable results help with SOC 2, ISO 27001 and PCI DSS audits.

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

Questions & Answers

As answered by people managing PowerDMARC and ShellNewHandler.

What's the story behind your product?

PowerDMARC's answer

The idea for PowerDMARC came from noticing how businesses, both small and large, fall victim to very basic cyber attacks and fail to protect themselves from impersonation, email spoofing, and phishing, and are not able to afford basic cybersecurity protection due to the high cost and complexity of setup. The vulnerability we protect from is not allowing hackers to send emails from your exact domain name itself. Imagine if someone sends an email from your company’s domain name - how would anyone understand that this email is not real?

Many organizations across the globe lose billions of dollars every day due to hackers spoofing their own exact domains due to existing vulnerabilities in email protocols. The solutions that existed in the market were very expensive, inaccessible for many businesses, and very hard to set up and configure. The idea was to make domain and email protection very simple and provide it at a super affordable price for all organizations, with no technical knowledge requirement.

What makes your product unique?

PowerDMARC's answer

AI-Native Email Authentication

  • MCP Server: a hosted MCP server that connects Claude, Cursor, ChatGPT and other MCP-compatible assistants to your PowerDMARC account. You can query reports, check domain health and manage DNS records in plain English.
  • DMARC AI Agent: a built-in assistant that diagnoses SPF, DKIM and DMARC failures and spam placement issues in real time.
  • AI-driven threat intelligence: scores each sending IP by risk based on how it behaves, not just whether it’s on a blacklist.

MSP/MSSP-First Approach

  • A multi-tenant, white-label platform designed for MSPs and MSSPs.
  • Partners can fully rebrand the platform, manage multiple clients under one console, and scale domain security as a service.
  • Most competitors focus directly on end-users, while PowerDMARC empowers partners to build a business model around DMARC.

Complete Email Authentication Suite (Beyond DMARC)

  • Instead of just offering DMARC monitoring, PowerDMARC integrates all key email security protocols in one platform:
  • DMARC, SPF, DKIM
  • MTA-STS & TLS-RPT (to enforce encrypted mail transfer)
  • BIMI (visual trust with brand logos)
  • Hosted DKIM, Hosted BIMI, Hosted SPF, Hosted DMARC, and Hosted MTA-STS services

This makes it a one-stop solution instead of piecing together multiple tools.

DNS Security Compliance

  • Daily automated checks of DNSSEC, CAA records, dangling CNAMEs, nameserver health, SSL/TLS certificates and domain transfer locks.
  • Each domain gets a 0–100 score (graded A to F) with step-by-step fixes. Checks are mapped to NIST SP 800-81r3, and the exportable results support SOC 2, ISO 27001 and PCI DSS audits.

Email Deliverability

  • Inbox placement testing across Gmail, Outlook, Yahoo, iCloud, Zoho and AWS.
  • Reputation and blocklist monitoring, plus support for meeting Google, Yahoo and Microsoft bulk sender requirements

Advanced Reporting & Threat Intelligence

  • User-friendly dashboards that convert raw DMARC XML reports into clear visuals.
  • Forensic report redaction & encryption for GDPR compliance.
  • Spoofing & phishing source tracing with real-time intelligence.
  • AI-powered insights (e.g., spoofing patterns, misconfiguration alerts).

Automated Policy Enforcement

  • Guided path from monitoring → quarantine → reject to make DMARC adoption stress-free.
  • Click-to-publish DNS records.
  • Automated recommendations that simplify what’s usually a complex manual process.

Enterprise-Grade Security & Compliance

  • SOC 2, ISO 27001, and GDPR compliance built into the platform.
  • Role-based access controls, SSO, and MFA for organizations.
  • Privacy-conscious forensic report handling.

Human-Backed Managed Services

  • Unlike some self-service platforms, PowerDMARC provides expert support and managed DMARC services.
  • Dedicated teams help enterprises and partners through onboarding, DNS record publishing, and policy enforcement.
  • This hand-holding drastically reduces the risk of email outages during rollout.

Continuous Innovation & Niche Focus

  • Regularly introduces new features (analytics, reporting, integrations) ahead of competitors.
  • Strong focus on education, awareness, and training (DMARC training courses, MSP enablement campaigns).

Why should a person choose your product over its competitors?

PowerDMARC's answer

PowerDMARC offers more than just basic DMARC protections and analytics. Its host of unique and advanced features makes it stand out among competitors:

  • A complete email authentication hosted service suite, including DMARC, SPF, DKIM, MTA-STS, TLS-RPT and BIMI
  • Hosted MCP server for managing DMARC through AI assistants (Claude, Cursor, ChatGPT)
  • Built-in DMARC AI Agent for instant troubleshooting
  • DNS security compliance scoring and inbox placement testing
  • Zero-touch, one-click SPF optimization using Macros
  • Forensic reports with PGP encryption
  • Full-platform white labeling for MSSPs
  • Multi-language support for 11 global languages
  • Responsive human support
  • Advanced Threat Intelligence insights and analytics

How would you describe the primary audience of your product?

PowerDMARC's answer

PowerDMARC serves organizations of all sizes, from SMBs to enterprises and government agencies, as well as MSPs and MSSPs that offer email security as a service. Typical users are IT and security teams, email administrators, compliance and GRC teams preparing for audits, and marketing and email teams who need reliable deliverability.

Which are the primary technologies used for building your product?

PowerDMARC's answer

PowerDMARC is built on email authentication protocols (DMARC, SPF, DKIM, MTA-STS, TLS-RPT and BIMI), DNS security standards (DNSSEC and CAA), AI and machine learning for threat intelligence, the Model Context Protocol (MCP) for AI assistant integrations, and a REST API for automation.
