Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Forward Email
- Self-hosting is complex and far less documented than the hosted service
- Newsletter/campaign tooling is thin compared to Mailchimp
- BUSL-1.1 license is source-available, not fully OSI-open
- Running production email requires significant infra and DNS expertise
Postal
- You are responsible for IP reputation, warmup, and deliverability
- Requires MariaDB, RabbitMQ, and DNS/DKIM configuration to run
- No marketing-campaign UI — it is a delivery engine, not a newsletter builder
- Less hand-holding than managed providers for spam/blocklist issues
Bottom line
Choose Postal if you want the lower-effort setup; choose Postal for the larger community and ecosystem. Postal has seen more recent development. Open each guide below for deploy steps and the full feature gap.
