MX Layer Outbound Email Filtering vs Red Sift OnDMARC: Side-by-Side Comparison (2026)

MX Layer Outbound Email Filtering

Startup and SMB security teams drowning in outbound spam and phishing will see immediate ROI from MX Layer Outbound Email Filtering because it stops compromised employee accounts from becoming distribution channels before they tank your IP reputation. The platform covers the full PR.DS and PR.PS attack surface,data scanning, authentication record management, and rate limiting,without forcing you to rip out existing inbound tools. Skip this if you need unified inbound and outbound filtering from a single vendor or plan to scale aggressively past mid-market; the four-person team behind MX Layer means you're betting on tight product focus over feature expansion.

Red Sift OnDMARC

SMB and mid-market teams without dedicated email security staff should pick Red Sift OnDMARC because it automates DMARC, SPF, and DKIM enforcement without requiring DNS expertise to implement. The platform handles policy tuning and enforcement across multi-domain environments, which means your team can protect brand-spoofing attacks without learning authentication protocols inside out. Skip this if you're an enterprise with 500+ domains and existing Proofpoint or Mimecast infrastructure; OnDMARC's strength is simplicity for smaller deployments, not replacing mature email gateways.
