Deep Dive: Switching from EmailOctopus to listmonk
Trade-offs, installation & data architecture
What you trade away

Docker Compose or a single release binary plus PostgreSQL
What it takes to run
You still need a PostgreSQL database and a trustworthy SMTP/API sender with authenticated DNS.
Where your data lives

Why fork listmonk instead of vibe-coding a EmailOctopus clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For EmailOctopus, manage a small subscriber list and send compliant campaigns through a hosted provider. The hard boundary is deliverability, templates, automations, landing pages, and customer support, plus deliverability, growth network, and integrations.
