4SecureMail vs VibeMail

4SecureMail provides secure email accounts and managed email hosting for businesses and consumers. Accounts support POP, IMAP, and SMTP with SSL/TLS and work with standard clients such as Outlook and Thunderbird. SecureVault encrypts sensitive outgoing email for outside recipients, who read and reply through a secure web link. Spam protection includes SpamAssassin and a challenge/response whitelist; a server-based ICSA-certified virus scanner is also included. The FAQ says SSL/TLS sessions begin before login credentials are exchanged, and that TLS 1.2 and Perfect Forward Secrecy are supported. The company describes support for HIPAA, GLB, and SOX, can provide or review a Business Associate Agreement, and offers off-site legal archiving at additional cost. IMAP IDLE notifications and simultaneous connections from multiple devices are supported. Outgoing attachments can total up to 5 GB across all recipients. Plans range from one mailbox with 500 MB of storage and no custom domain to options with multiple mailboxes, more storage, and custom domains. The service has no free plan but offers a free trial; listed pricing starts at $8.24/mo. It is available worldwide to holders of major credit cards and supports U.S. currency.

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.
