Feature set
MXtoolbox provides a broad suite of email deliverability tools, extending beyond just DMARC. When we've used it, we found its DMARC reporting to be a component of a larger system that includes SPF and DKIM monitoring, deliverability diagnostics, and domain impersonation protection. It offers a more managed approach, abstracting away some of the complexities of DMARC report analysis with its curated dashboards and alerts.
Beyond DMARC, MXtoolbox is well-known for its extensive blocklist (or blacklist) monitoring, giving us proactive alerts when our IPs or domains land on one. Features like SPF flattening in higher tiers demonstrate its commitment to resolving common email authentication challenges, making it a comprehensive solution for ensuring email reaches its destination.
Parseddmarc, by contrast, is a highly specialized open-source Python package and command-line utility. Its core strength lies in parsing DMARC reports, including aggregate (RUA) and forensic (RUF) reports, as well as SMTP TLS Reporting. For us, this means it's a foundational tool, not an all-in-one platform. It's about data processing, not a polished user interface for analysis.
As a self-hosted solution, Parseddmarc offers immense flexibility. It can pull reports via IMAP, Microsoft Graph, or the Gmail API, and output results in JSON or CSV. This allows us to integrate DMARC data into existing monitoring and analytics platforms like Elasticsearch, OpenSearch, Splunk, or Apache Kafka, which then provide the visual dashboards and alerting capabilities.
