Sublime Email Security Platform Pricing Overview

Sublime Email Security Platform does not offer a permanent free plan, but it does provide a free trial that lets users to test the product before committing to a paid plan. Trial availability and duration may vary, so users should review the seller's official pricing page for the most current details.

Sublime Email Security Platform's pricing structure suits a wide range of buyers. The free Core tier fits individual security practitioners, small businesses under 100 mailboxes, and teams evaluating the platform — G2 reviewers in small businesses confirm it feels complete at no cost. The Enterprise tier targets mid-market and large organizations; G2 reviewers from Oil & Energy, Legal Services, Financial Services, Education, Retail, and Computer Software all operate at enterprise scale and praise custom detection via MQL, API integrations, and automated remediation. Security-mature teams with dedicated analysts extract the most value, while organizations wanting a low-maintenance, deploy-and-forget solution also find Sublime Email Security Platform's Enterprise pricing justified by reduced SOC workload.

Sublime Email Security Platform's Core tier is free for the first 100 mailboxes, covering the detection engine, sender behavioral profiles, spam and graymail detection, and allowlisting/blocklisting — sufficient for individual practitioners or small teams. G2 reviewers confirm seamless onboarding and strong out-of-the-box coverage even at this tier. Sublime Email Security Platform's Enterprise tier, priced via custom quote, adds vendor impersonation and compromise detection, dynamic link analysis, email bombing protection, premium support, and advanced controls. Enterprise reviewers specifically highlight automated remediation, API-driven workflows, and custom MQL detection rules as capabilities that drive the upgrade decision, none of which are available in the Core tier.

G2 reviewers rate Sublime Email Security Platform 4.5–5.0/5 across segments, signaling strong value. Enterprise reviewers in Oil & Energy, Manufacturing, Education, and IT cite 60–62% drops in phishing incidents, 400 hours of annual effort saved, and investigations reduced by 62% in the first quarter — concrete ROI that justifies premium pricing. One reviewer flags that pricing ramps up quickly as mailboxes grow, and another notes the Enterprise tier lacks outbound features and some reporting depth. Reviewers who migrated from Mimecast and Avanan consistently rate Sublime Email Security Platform's pricing favorably relative to detection quality, low false positives, and minimal tuning overhead, positioning it as a high-value investment rather than a budget option.
