By Mert Ozdemir, Head of Deliverability · Apr 30, 2026 · 6 min read · Last reviewed Apr 30, 2026

EmailGuard monitors cold email deliverability continuously. This review covers features, pricing, and whether it replaces GlockApps for placement monitoring.

EmailGuard Review: Continuous Deliverability Monitoring

EmailGuard (emailguard.com) takes a continuous monitoring approach to cold email deliverability instead of GlockApps test-based model. Automated inbox placement monitoring across multiple seed addresses, alerting on deliverability drops, and integration with cold email platforms. For cold email operations at scale, continuous monitoring catches deliverability issues faster than periodic testing.

What EmailGuard Offers

  • Continuous inbox placement monitoring
  • Automated alerts on deliverability drops
  • Integration with Instantly, Smartlead, and other platforms
  • Multi-domain monitoring
  • SPF/DKIM/DMARC drift detection

EmailGuard Pricing

  • Starter: $49/month
  • Growth: $149/month
  • Enterprise: Custom

Where EmailGuard Wins

  • Continuous vs test-based monitoring
  • Automated alerting reduces manual testing
  • Platform integrations for cold email workflows
  • Cheaper than Folderly for monitoring-only needs

Where EmailGuard Loses

  • Narrower scope than Folderly (monitoring, not full deliverability platform)
  • Less diagnostic depth than GlockApps for detailed issue analysis
  • Smaller track record than established alternatives

Who EmailGuard Is Good For

  • Cold email agencies wanting continuous monitoring
  • Operations at scale where manual testing does not scale
  • Teams using Instantly or Smartlead with integration needs

Who Should Look Elsewhere

  • Teams needing deep diagnostic tools (GlockApps or Folderly)
  • Small operations where periodic testing is enough
  • Budget teams (Google Postmaster Tools free)
The verdict on EmailGuard: Solid continuous monitoring tool for cold email at scale. For one-time testing, GlockApps. For comprehensive deliverability platform, Folderly. EmailGuard fits between them.
