BillionMail is a self-hosted, open-source mail server and email marketing platform built on Postfix, Dovecot, and Rspamd, with campaign management, analytics, and Roundcube WebMail integrated. It is deployed via an install script or Docker Compose and lets users send newsletters and transactional emails without monthly SaaS fees.

Use cases

• self-host a complete mail server with SMTP, IMAP, and spam filtering
• send newsletters and email marketing campaigns from my own domain
• replace expensive SaaS email tools like Mailchimp with a free alternative
• run cold outreach campaigns with unlimited sending
• track open rates, click-through rates, and deliverability for email campaigns
• manage mailing lists and customer segments with tags
• set up SPF, DKIM, and DMARC records with guided DNS configuration

When to choose

• you want full control over your email infrastructure and data without monthly fees
• you need both a mail server and a marketing/newsletter platform in one self-hosted package
• you want one-click deployment with guided DNS and SSL setup
• you're comfortable running Linux servers or Docker

When to avoid

• you need a managed service with guaranteed deliverability and IP reputation
• you only need transactional email via API without campaign features
• you cannot host on your own server or obtain a clean sending IP
• you require AGPL-incompatible licensing for commercial redistribution
