What you give up either way
- Built-in sending infrastructure and deliverability expertise (reputation maintenance, dedicated IP)
- Production-hardened reply-classification guardrails and legal/complaint protections
- Polish of integrations (one-click Clerk/Stripe/Supabase connections) and ML-backed playbook
- Operational monitoring, weekly plain-language reporting, and ongoing model tuning
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Mara, and it does not prove anyone has run it for a month. How we decide.
