Serif vs UnInbox

Serif places an AI employee in shared email addresses such as info@, support@ and billing@ to handle routine messages. It connects to Google Workspace or Microsoft 365, or can work with an address of its own. The assistant can qualify and route inquiries, answer common questions, collect paperwork, send quotes and follow up on unpaid invoices. Ambiguous or sensitive messages are escalated to the team, and users can approve replies before allowing independent operation. The shared inbox page offers $100 in free credits without a credit card, and each plan includes a 7-day free trial with full access. Listed plans include Lite at $30 a month, Standard at $50 a month, Pro at $200 a month, and Team at $50 a month per user; each is billed monthly. Serif says it is SOC 2 Type 2, GDPR and HIPAA compliant, and that emails are neither used to train general AI models nor stored on its servers. Apps are listed for web, macOS, Windows and iOS; Android is coming soon.

UnInbox is collaborative email software for teams and professionals. It provides shared inboxes, shared spaces, and workflow statuses so teammates can comment on conversations, reply from shared addresses, and see whether work is complete. Users can add unlimited addresses, including admin@, support@, sales@, and billing@ examples. The codebase is open source, with instructions for running it locally; self-hosting requires additional manual email configuration and production guidance through Discord. A free plan costs nothing @uninbox.me email address and includes personal spaces, three workflows per space, seven-day raw email retention, and community or email support. Pro costs $12 a month billed per user, adding teams, unlimited custom domains, shared and public spaces, SMTP and API access, assignees, and priority support. Enterprise has no listed price, requires 30 users, and adds dedicated infrastructure, SAML SSO, long retention, onboarding, and organization-wide video support.
