VibeMail provides encrypted private email with multiple addresses, custom domains, and a transactional email API. It runs on Android, iOS, web, and through an API. Message bodies are encrypted at rest and in transit; the maker says it cannot read mail sealed with a password-derived key. Each alias has its own encryption identity. VibeMail says it shows no ads, does not profile users, and does not train models on customer mail. Incoming mail is scanned for spam and malware before encryption. The API supports templates, webhooks, delivery tracking, and suppression handling, with SDKs for TypeScript, Python, Go, and Rust, plus MCP and REST access. IMAPS, submission, and POP3S are supported, and the maker says Apple Mail, Gmail, and Outlook on mobile can connect through IMAP and SMTP. The free plan costs nothing forever with one encrypted address, 500 MB storage, and web access. Paid plans start at $2.99 a month; overage sends cost $0.60 per 1,000.
