What Mailtrack.io does

Mailsuite S.L., operating as Mailsuite and formerly known as Mailtrack, is a Barcelona-headquartered, founder/management-owned software company founded around 2015 and rebranded from Mailtrack to Mailsuite in January 2024. The company builds a unified email productivity suite integrated natively with Gmail and Outlook via OAuth2, anchored by a pixel-based email tracker that delivers real-time open and link-click notifications, with patented Debeaconizer technology for tracking accuracy and self-open/bot protection. Around that tracker, Mailsuite has assembled a horizontal suite that includes Mail Merge and Mass Email campaigns (up to 10,000 sends per campaign), Follow-up Reminders, Email Analytics, Document Tracking with per-page engagement, Secure Document Sharing with access controls and watermarks, in-Gmail e-Signature, Video Messages, Email Templates, and a CRM for Gmail, with companion mobile apps on Android and iOS and a Microsoft Outlook add-in distributed via AppSource.

The business runs on a product-led, freemium GTM model: users self-onboard via the Chrome Web Store, Microsoft AppSource, Google Play, or the Apple App Store, use a free tier with limited tracking, and upgrade to PRO or ADVANCED paid subscriptions for unlimited tracking, advanced analytics, document and signature features, and team functionality. Pricing is not publicly disclosed but follows standard monthly/annual SaaS billing. The company reports 3M+ total users, 116,000+ paying subscribers/companies, 11,500+ Chrome Web Store reviews at a 4.5-star rating, and availability in 12+ languages. Customers are predominantly SMBs and individual professionals across sales, real estate, education, e-commerce, and professional services. Backed by AWS infrastructure in Ireland, ISO 27001 certification, full GDPR compliance, and Google Verified Partner status (passed annual audits with no vulnerabilities), Mailsuite is positioned as a low-friction, distribution-led productivity layer sitting on top of the two dominant consumer/business email platforms.
