Octeth

What Octeth does

Octeth is a self-hosted email marketing platform operated by 50SAAS, LLC, founded in 1999 by Cem Hurturk and headquartered in Istanbul with offices in New York and London. The company targets digital marketing agencies that manage email campaigns on behalf of multiple clients, offering a perpetual software license starting at $5,000 that allows agencies to deploy the platform on their own cloud infrastructure (AWS, DigitalOcean, or similar) and rebrand it fully under their own domain. The product is positioned as an economic alternative to per-seat SaaS email platforms, where a 10-client agency would otherwise pay $60,000-$120,000 per year in subscription fees.

The platform is built on a Docker-containerized architecture with a horizontally scalable send engine, MySQL 8.0 for transactional storage, ClickHouse for analytics, Redis for caching, RabbitMQ for message queuing, and Caddy for automatic SSL/TLS. It exposes 315+ REST API endpoints, supports JSON and XML payloads, and integrates with major email gateways (Amazon SES, Mailgun, SendGrid, SparkPost) and SMTP servers (PowerMTA, KumoMTA, Halon, Postfix). Core features include a drag-and-drop email builder (Stripo and Unlayer), visual Journey Builder with 11 automation actions, A/B and multivariate testing, SMS marketing via Infobip, multi-tenant account management with user impersonation, Google Postmaster Tools OAuth integration, an extensible plugin system with 160+ action hooks and 30+ filter hooks, and full white-labeling of UI and email output. The company also operates a sub-brand ecosystem including Cleanify (email list validation), IPMonitor (IP reputation monitoring), and Sendloop (a SaaS email marketing product under the same parent).

Octeth's go-to-market is a hybrid enterprise field sales motion combined with a freemium self-serve tier: agencies can book 30-minute demos or evaluate the product through a free Community Edition supporting up to 10,000 subscribers, then convert to a perpetual license with optional annual service packages at $3,000-$5,000/year and an optional $1,275 premium installation service. Distribution is global with 138 countries served, 500+ active clients across diverse industries (financial services, telecommunications, government, travel, customer experience management), 20,000+ cumulative installations, 1B+ emails sent monthly, and 2M+ emails sent daily. The company is bootstrapped, founder-owned, and has not raised external funding.
