Paubox Email Encryption vs Xeams

Paubox Email Encryption is a web service for sending protected email, presented through its healthcare solution. Delivery uses a link, and recipients verify access with a password. Outlook and Gmail integrations are included, along with administrator access controls. Messages do not expire, and attachments have a listed limit of 150. Paubox has no free plan, but offers a 14-day trial. Its three plans are billed annually and cover up to five senders: Standard costs $29 a month, Plus costs $59 a month, and Premium costs $69 a month. The pricing note gives a starting price of $29/mo on an annual term. Buyers can compare the plan levels while considering link-based delivery, password verification, supported mail integrations, and the administrative controls available for a small sender group.

Xeams is an email server and spam firewall that can run standalone, sit in front of another mail server, or operate in hybrid mode. It supports SMTP, POP3, and IMAP, alongside email technologies including DKIM, SPF, DMARC, and MTA-STS. Filtering uses sender reputation, authentication checks, attachment and content rules, Bayesian analysis, and virus checks. Administrators use a web interface for live monitoring, logs, reports, retention settings, and tiered administration. Quarantined messages are kept on the server for 15 days by default and can be reached through the web interface or an IMAP client. Integrations include Active Directory and OAuth 2.0 outbound relaying for services such as Microsoft Exchange Online or Google Workspace. Outbound tools include DKIM signing, REST APIs, webhooks, campaigns, read receipts, and header sanitization. A new installation has Enterprise features for 30 days before converting to Community Edition unless licensed. Community Edition is free for up to 5 personal hobby users when spam filtering is used; its spam filtering is otherwise limited to 5 users. Enterprise Edition with Support is $300 a year per deployed instance; Enterprise per-user prices vary by tier.
