The record

Purpose: MailFlow classifies incoming email into IMAP folders and generates draft replies in the user's writing style.
Classification: It classifies mail using internal or client domains, threads, and keywords, with an LLM fallback.
Drafts: Generated replies are saved to the IMAP Drafts folder and MailFlow never sends email automatically.
LLM integrations: The project lists Ollama, OpenAI, Anthropic, Gemini, vLLM, LM Studio, and OpenAI-compatible endpoints as supported LLM options.
Email integrations: Mailboxes can connect through generic IMAP or OAuth2 for Gmail and Microsoft 365.
Self-hosting: MailFlow can be run as a full web, API, and worker stack using Docker Compose.
Privacy: The project recommends local Ollama for privacy and supports self-hosting.
Credential security: The SECURITY file says a Fernet SECRET_KEY encrypts stored IMAP passwords and LLM API keys.
Security notice: The security file warns that an early development SECRET_KEY appeared in Git history and should not be reused for deployments.
Language: The README lists English and Spanish bilingual support.
Limits: In managed multi-tenant mode, the listed Free plan limit is 1 mailbox and 100 emails per day; self-hosted instances have no plan limits.
Roadmap: Template library, correction-based learning, writing-style capture, and semantic search are listed as not yet implemented roadmap items.
Headquarters: Coves de Vinromà, Castellón, Spain
Price from: $12/mo
