Mimecast offers 3 pricing tiers: Critical, Advanced, Premium. The Advanced plan is enhanced security with dlp.

Compared to other email security software, Mimecast is positioned at the budget-friendly price point.

Mimecast is a comprehensive email security platform offering protection against phishing, ransomware, business email compromise, and data loss. Serving thousands of organizations globally, Mimecast provides tiered solutions from basic threat filtering to advanced AI-powered detection with archiving and compliance features.

As of August 2025, Mimecast introduced new email security plans with custom pricing based on organization size and selected features. Plans range from Critical (core anti-phishing and spam filtering) to Premium (full suite with archiving, DLP, and security training). Pricing estimates suggest $5-15 per user/month depending on tier and deployment scale.

Mimecast uses a subscription-based model requiring custom quotes. While the platform offers robust email security and unified management, customers should budget for potential renewal increases, data export fees if migrating, and bundled features in premium tiers that may exceed actual needs.

Frequently Asked Questions

01 How much does Mimecast cost per user?

Mimecast uses custom pricing based on organization size and features. Estimates suggest $5-15 per user/month depending on the tier (Critical, Advanced, or Premium). Small businesses typically pay toward the lower end, while enterprises with full archiving and DLP pay more. New plans introduced in August 2025 require contacting sales for quotes.

02 Does Mimecast offer a free trial?

Mimecast does not offer a free plan, but free trials are available upon request. Contact Mimecast sales to arrange a trial period. The trial typically includes access to email security features, threat detection, and reporting to evaluate the platform before committing to a subscription.

03 What are the hidden costs of Mimecast?

Major hidden costs include data export fees when migrating away from Mimecast (can double migration costs), premium phone support charges for SMBs, bundled features like security awareness training in premium tiers (charged even if unused), and significant renewal price increases (25%+ reported). Migration throttling of ~1TB/week can also delay projects and increase costs.

04 How does Mimecast compare to Proofpoint?

Both offer comprehensive email security with similar features (anti-phishing, archiving, DLP). Mimecast ($5-15/user/month) uses custom pricing with bundled tiers, while Proofpoint Essentials ($2-6/user/month) has transparent pricing for SMBs. Proofpoint is often more affordable with modular add-ons. Mimecast is known for steep renewal increases and data export fees, while Proofpoint offers more predictable costs.

05 Why are Mimecast customers switching away?

Common reasons include steep renewal price increases (25%+ annually), expensive data export fees when migrating, vendor lock-in with slow migration throttling (~1TB/week), and bundled features that force customers to pay for unused services like training. Some customers also report less transparent pricing since 2021 and challenges with support accessibility.

06 Is Mimecast good for small businesses?

Mimecast can work for small businesses needing comprehensive email security, but pricing may be less competitive than alternatives like Proofpoint Essentials or Barracuda. Mimecast now charges SMBs for phone support (previously free), and custom pricing makes cost comparison difficult. Consider simpler, more transparent solutions if you don't need all premium features.
