Octeth is a self-hosted email marketing platform for agencies, SaaS companies and enterprises that is deployed on the customer's own server (via Docker) rather than used as a hosted SaaS product. It provides email campaign creation, marketing automation (journeys and autoresponders), transactional email sending, SMS marketing, deliverability tools, reporting, and a white-label multi-tenant ESP for agencies to resell under their own brand. It is sold as a one-time perpetual license rather than a recurring subscription, and offers a free self-hosted Community Edition for smaller subscriber lists.

Pricing

Pricing is a one-time perpetual license rather than a subscription; the license excludes server hosting costs and third-party email delivery fees (e.g., Amazon SES, billed per email by the provider). A 5-year cost comparison on the site cites an average SaaS ESP cost of ~$10,500/year (about $52,500 over 5 years for 100K subscribers) versus a one-time $5,500 Octeth license, for savings of $47,000+; a separate note cites 10-client agency setups costing $9K–$20K on Octeth versus $60K–$120K/year on typical SaaS platforms. All licenses carry a 30-day money-back guarantee.
