Outsourced email management services
Reply targets you choose
From 1 hour to 24 hours, depending on what your customers expect.
Our helpdesk or yours
We run your inbox in our own helpdesk, or work in yours. We have worked in Zendesk, Shopify and Zoho CRM.
Quality measured
We track customer satisfaction, reply times and missed targets, and review them with you.
Shared or dedicated
Shared agents for low volume, a dedicated team for busy inboxes.
Email stays with people. Want AI on calls and chat?
Trained agents handle your inbox. On your phone and website chat, AI can answer first and take routine questions, with our agents right behind it. A trained person is always one step away.
How AI and our agents work together →- On calls and chats, customers can ask for a person anytime
- Handovers happen in the same call or chat, with everything already collected
- AI uses only your approved knowledge base, so prices and policies stay accurate
- Every email, call and chat is logged in one inbox, with AI replies clearly marked
