Self-hosted email marketing you pay for once, with unlimited subscribers
Email marketing software you install on your own Ubuntu server with one command, then use to send newsletters, automated sequences and transactional email through Amazon SES, Postmark, Mailgun, SendGrid or any SMTP service. A setup wizard verifies your sending domain and rechecks SPF, DKIM and DMARC every few hours, and an API, Node and Python SDKs, webhooks and a command-line tool let an AI agent such as Claude Code install and run it. It is sold as a licence you pay for once, with every feature and unlimited subscribers: Regular ($250) covers one server for your own business, Agency ($450) up to 5 servers for client work, and Extended ($1,000) up to 25, with a 30-day money-back guarantee. It is made by Furvur Inc in Canada.
