What is N-able Mail Assure
N-able Mail Assure is a cloud-based email security service that filters inbound and outbound mail to reduce spam, phishing, malware, and spoofing risks. It is commonly used by managed service providers (MSPs) and IT teams supporting small and mid-sized organizations that run Microsoft 365, Google Workspace, or on-premises mail servers. The service combines policy-based filtering with encryption options and continuity features designed to keep email flowing during mail server or cloud email outages. Administration is typically performed through a centralized console intended for multi-tenant management.
Multi-tenant MSP administration
Mail Assure is designed for service providers managing multiple customer environments from a single console. It supports customer-level separation and delegated administration workflows that fit common MSP operating models. This structure can reduce overhead compared with tools that are primarily single-tenant and require separate instances per customer.
Layered email threat filtering
The product focuses on gateway-level controls such as anti-spam, anti-phishing, and malware filtering before messages reach the mailbox. It also supports policy-driven handling (allow/block, quarantine, and routing decisions) to standardize enforcement across domains. Gateway filtering can complement native protections in cloud email platforms by adding an independent control point.
Continuity and message spooling
Mail Assure includes continuity-oriented capabilities intended to reduce disruption during email service outages. When the primary mail system is unavailable, the service can queue mail and provide access paths that help users send and receive messages. This can be useful for organizations that require basic email availability even when their mail host experiences downtime.
Archiving is not the core
Although it can retain and provide access to messages for continuity and recovery scenarios, the product is not primarily positioned as a full compliance-grade email archiving platform. Organizations with strict retention, supervision, legal hold, and eDiscovery requirements may need a dedicated archive with deeper governance controls. Fit depends on regulatory scope and the level of auditability required.
Limited advanced compliance workflows
Compared with products built specifically for regulated communications, Mail Assure may offer fewer native features for complex review workflows, supervision, and granular retention exceptions. Reporting and audit trails may be sufficient for operational needs but not for all compliance programs. Buyers should validate required certifications, retention controls, and export formats for their industry.
Feature depth varies by use case
The product’s strength is broad gateway protection and MSP operations rather than highly specialized security functions. Organizations seeking extensive data loss prevention, advanced user behavior controls, or deep integration into security operations workflows may find gaps. Evaluation typically requires mapping required controls (encryption, impersonation protection, policy granularity) to the specific plan and configuration.
Plan & Pricing
Pricing model: Per-mailbox subscription (monthly). Email protection (inbound/outbound filtering) is billed per protected mailbox; email archiving is charged separately and uses a fair-usage model (50 GB compressed storage included per archived mailbox). Minimum-commitment (volume/annual) options are supported and overages are billed per mailbox above the commitment. Official site does not publish standard per-mailbox list prices; customers are asked to contact sales or request a quote.
Free tier/trial: 30-day free trial (no credit card required).
Example costs (official site examples / illustrative only): The official Mail Assure Billing FAQ shows an illustrative example of an annual 12-month charge for 50 mailboxes at $1.00/month (used in the FAQ to explain invoice layout). This is presented as an example in the vendor FAQ, not as a published list price.
Other pricing notes from official documentation:
- Email archiving: 50 GB compressed storage allocation included per mailbox; over-usage is billed against agreed-upon rates and counted as additional archived mailboxes as described in the FAQ.
- Billing methods: automatic mailbox detection (billed for unique mailboxes filtered during the month) or manual mailbox provisioning (billed for mailboxes with filtering enabled on the last day of the month). The FAQ also documents how minimum-commitment invoices and overages appear.
- For published pricing or to receive a formal quote, the vendor directs customers to Contact Sales or Get a Quote.
