About BillionMail
BillionMail is an open source mail server, newsletter, and email marketing platform that runs entirely on infrastructure the operator controls. It is written in Go and released under the AGPL 3.0 license, and it lives in the self hosted email and marketing ecosystem alongside the mail transfer and delivery components it bundles, including Postfix, Dovecot, and Rspamd. The project ships as a complete stack rather than a single binary, combining a sending server, a campaign manager, and a webmail client so that one deployment covers transactional mail, promotional campaigns, and newsletters.
