Deep Dive: Switching from Brevo to Plunk
Trade-offs, installation & data architecture
What you trade away
Plunk handles both transactional and campaign email, but self-hosting its multi-service stack and configuring SES is much less turnkey than Brevo's managed sending and compliance workflow.
How to deploy Plunk
Hosted signup or Docker Compose
What it takes to run
The self-host path needs Docker, several subdomains, DNS/TLS, and an AWS SES account with credentials and domain verification.
Where your data lives
Self-hosted data lives in PostgreSQL, queues in Redis, and uploads in bundled MinIO or another S3-compatible store.
Why fork Plunk instead of vibe-coding a Brevo clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Brevo, send a low-volume newsletter and transactional messages with clear consent records. The hard boundary is deliverability infrastructure, multichannel messaging, crm, automation, and support, plus deliverability, growth network, and integrations.
