MailHippo vs Secure Message

MailHippo is a secure email messaging platform designed to protect patient data with HIPAA-compliant email. It works with a user's existing email address and provider, and MailHippo says users can begin sending and receiving encrypted messages without setup or configuration. SendSafe provides a personalized URL through which anyone can send an encrypted message to a MailHippo inbox, including people without a subscription. Messages use SSL/TLS 1.2 or higher in transit, while message bodies and attachments are protected with AES-256 encryption at rest; the key ring is also encrypted. Every plan includes a HIPAA Business Associate Agreement, and message-access records include the authorized user, date, time, and records accessed. The API supports attachments, CC/BCC, HTML content, and inbound messages through a webhook. Basic costs $4.95 a month per user and Pro costs $7.95 a month per user; both are month-to-month. A 30-day trial is available, and there is no free plan. MailHippo was founded in 2019 and is headquartered in Pompano Beach, Florida.

Secure Message is a self-hosted inbound email gateway that filters mail before it reaches an existing mail server. Its Community features include Postfix content filtering, spam scoring, DNSBL, SPF, DKIM and DMARC checks, quarantine, mail logs and administrator MFA. Professional adds a recipient web portal: recipients open protected messages with a one-time code, without an account or app. Its rules can encrypt, redirect or block sensitive outbound messages, and recipient checks can use SMTP callout, LDAP or directory lookups. Stored messages, attachments and quarantine use Fernet encryption with AES-128-CBC and HMAC-SHA256; the key remains on the customer host. Access controls include TOTP administrator MFA, role-based access and audit logging, with logs exportable to CSV. Enterprise adds AI Autopilot tuning, eDiscovery and archive search, DLP and disclaimers; Autopilot and the classifier are off by default. The gateway can sit in front of Microsoft 365 or an existing mail server without mailbox migration. The single-node appliance runs on Debian 13, with 2 vCPU and 4 GB RAM recommended as a starting point.
