In their own words
Serif
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.
