Important restrictions
This is an email app/client, not a free hosted mailbox or SMTP delivery service. Self-hosting requires Node.js, PostgreSQL, Docker and appropriate configuration; Gmail/Outlook access, Google OAuth, AI models, Cloudflare storage/workers, Twilio, Autumn or other integrations may require credentials and incur separate charges. MIT copyright/license notices apply.
Independent community listing, not affiliated with the provider. Always check the latest billing policy and quotas before enabling paid usage.
