TitanHQ SpamTitan is the flagship email security product from TitanHQ, an Irish cybersecurity vendor that has built a strong SMB and MSP-channel reputation since 1999. SpamTitan, alongside sister products WebTitan (DNS filter) and ArcTitan (email archiving), serves more than 12,000 businesses and 3,000+ MSP partners as of 2026 according to vendor data.
The product's defining proposition is enterprise-grade email security at SMB-affordable pricing. Where Mimecast and Proofpoint typically target organizations with 500+ employees and price accordingly, SpamTitan targets the underserved 10-500 employee tier with a simpler product, MSP-friendly multi-tenant management, and pricing that scales linearly with mailbox count rather than locking customers into enterprise commitment tiers.
**Pricing (as of 2026):** TitanHQ does not publish a standard rate card — pricing is custom and negotiated per organization. As a general benchmark, SpamTitan typically prices in the $1.50-$3.00 per mailbox per month range for SMBs, with volume discounts at 100+ mailboxes. MSP partners receive margin-protected pricing for white-label deployments. Pricing also scales with selected modules (anti-spam, link protection, attachment sandboxing).
SpamTitan deploys as a cloud gateway in front of Microsoft 365, Google Workspace, or on-premise Exchange — inspecting inbound and outbound mail before delivery. The platform includes link protection (URL rewriting with sandbox analysis at click-time), attachment sandboxing for unknown file analysis, anti-impersonation controls, and zero-day phishing detection.
According to G2 and Capterra (combined 600+ reviews as of Q1 2026), TitanHQ SpamTitan reviewers most frequently cite the spam catch rate, the responsive customer support, and the MSP-friendly architecture as standout strengths.

Important details to help you make the right choice
SMBs and MSPs that need cost-effective anti-spam, anti-phishing, and link protection for Microsoft 365 or Google Workspace — without enterprise-platform pricing.
Not the right fit for very large enterprises (5,000+ mailboxes) where Mimecast / Proofpoint enterprise platforms offer deeper threat hunting and DMARC management at scale. Also less suited to organizations needing native Microsoft Defender for Office 365 integration over a third-party gateway.

Microsoft Defender for Office 365 (included with Microsoft 365 E5 and sold separately) is a strong native option for Microsoft 365 environments. TitanHQ SpamTitan is generally chosen as a complementary layer (defense in depth) or as a primary option for organizations that prefer a third-party gateway. SpamTitan's link click-time sandboxing is differentiated; Microsoft Defender's native integration is differentiated. Many SMBs run both — Microsoft Defender as the native layer, SpamTitan as the gateway in front of it.

Yes — both. SpamTitan deploys as a cloud gateway by changing your domain's MX records to point at SpamTitan, which then inspects inbound mail and delivers clean messages to Microsoft 365 or Google Workspace as the final mailbox. Outbound mail can also be routed through SpamTitan for outbound spam control and DLP. Setup is typically a 30-minute task involving DNS changes.
Link click-time sandboxing rewrites URLs in inbound emails so that when a user clicks a link, SpamTitan first analyzes the destination in a sandbox at that moment — catching phishing pages and malware that may have been activated after delivery. This is more effective than delivery-time-only URL inspection because attackers commonly weaponize URLs after the email lands in inboxes (to bypass delivery-time scanning).
Yes — MSP channel is one of TitanHQ's primary go-to-market motions. The MSP edition includes multi-tenant management, white-label options, monthly billing, and integrations with major PSA / RMM platforms (ConnectWise, Datto, Kaseya). Margin-protected pricing supports MSP profitability on the resold service. Many MSPs bundle SpamTitan with WebTitan (DNS filter) and ArcTitan (email archiving) as a unified TitanHQ stack.
TitanHQ does not publish a standard rate card — pricing is custom and negotiated per organization based on mailbox count, selected modules, and contract term. As a general benchmark, SpamTitan typically prices in the $1.50-$3.00 per mailbox per month range for SMBs with volume discounts at 100+ mailboxes. Get a custom quote at titanhq.com/contact.
