Frequently asked questions
What is an email AI agent?
An email AI agent is software that can automatically generate the first response to an inbound support ticket or apply the same deflection to the entire conversation. It pulls answers from your connected knowledge and replies, drafts or comments so your team does not have to handle every routine email by hand.
How does the email AI agent work?
The moment a ticket lands in a connected inbox, the Email AI Agent finds an answer in your knowledge base, articles or connected sources and delivers a response in the mode you choose. Tickets it cannot answer are left for your team.
What kinds of questions can it answer?
It is strongest on repeatable Tier 1 inquiries like hours, policies, account status and product questions. Complex or sensitive issues that need human judgment are best left to your agents.
Where does the Email AI Agent get its answers?
From the knowledge you already have. It draws on your knowledge base, published articles, indexed web content and connected systems, so answers stay consistent with every other channel.
Can I review responses before they send?
Yes. You can start in draft mode so a person approves every reply before it goes out, post answers as internal comments or enable automatic sending once you trust the output.
Does it work with my existing helpdesk?
It can sit in front of your existing helpdesk as a first-response layer, handling what it can and passing the rest into your current workflow. A Capacity specialist can walk you through your setup.
What if I don’t have a helpdesk tool?
Capacity includes a native Helpdesk, so if you don’t already have a ticketing tool, you get one out of the box.
How long does it take to get started?
Most teams configure a basic setup quickly and validate responses in draft mode before going live. Your implementation team will tailor the rollout to your inbox volume and knowledge.
How is it different from other support AI tools?
Most support automation tools have siloed channels with their own knowledge to maintain. The Capacity Email AI Agent uses the same Knowledge Base that power your Chat, Voice and SMS AI Agents.
