Best for DMARC
DMARC services summary
Navigating the world of email security protocols can feel overwhelming. Beyond DMARC, SPF, and DKIM, advanced standards like MTA-STS and TLS-RPT are becoming essential to protect your email communications. These protocols ensure that your emails are transmitted securely and that reports are generated when secure transmission fails, providing crucial visibility. We have thoroughly evaluated various DMARC services that offer hosted support for these vital protocols, simplifying their implementation and management.
To identify the leading DMARC services with hosted MTA-STS and TLS-RPT support, we rigorously assessed platforms based on several key criteria. Our goal was to provide an independent, expert review, highlighting strengths and weaknesses from a user's perspective. Our evaluation process involved looking beyond basic DMARC reporting capabilities to focus on comprehensive email authentication and security features. We prioritized services that offered a clear path to implementing and managing these complex protocols.
Hosted MTA-STS and TLS-RPT support: This was our primary filter. We specifically looked for services that actively host and manage these records, rather than just providing monitoring or requiring manual setup.
Ease of use: We assessed how intuitive each platform's interface was for setup, configuration, and ongoing monitoring. A user-friendly experience was crucial for high ranking.
Feature set: Beyond the core DMARC, SPF, and DKIM, we considered additional features like advanced reporting, threat intelligence, API access, and user management capabilities.
Pricing clarity and value: We analyzed the transparency of pricing models, the cost-effectiveness of different tiers, and the features included at each price point.
Customer support: The availability and responsiveness of support channels, including email, chat, and phone, were important factors.
User reviews: We incorporated aggregated user feedback to understand real-world experiences and identify common strengths and weaknesses.
