FlowCrypt vs MailHippo

FlowCrypt is an email encryption service that lets users send encrypted messages to OpenPGP users and password-protected messages to other recipients. Recipients can reply securely without installing a plugin. It is offered as a Chrome extension, with other platforms and a mobile application also listed. Gmail and Outlook integration are listed, along with message expiry and password-based recipient verification. The free plan is for fewer than 100 users and lists a 5 MB attachment threshold, while product details say free users can add attachments up to 25 MB. Enterprise supports domains with more than 100 users, and administrators can set domain-wide controls and enforce rules for passphrases, keys, and signing. Enterprise also supports SSO through Google, OIDC providers, and delegated identity providers, and can connect with public key servers, HSMs, and internal systems. Enterprise commercial-use pricing requires contacting FlowCrypt. Its enterprise data processing agreement is described as GDPR-compliant, and enterprise support includes an SLA for availability and response times for fixes and patches.

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.
