Your inbox, answered within the time you promise
Customers who wait days for a reply go elsewhere. Our agents work your inbox or helpdesk every day of the year and reply within the target you set.

What our agents do for you
- Customer questions, complaints and requests by email or ticket
- Order, booking and account changes within your rules
- Escalation to your team for anything outside your policy
- Tagging and reporting on the reasons customers contact you
How we run it
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.
Want AI on the first line? We do that too.
AI can answer first and handle the routine questions, with our agents right behind it for everything else. Or keep it people only. Your choice, and a person is always one step away.
How AI and our agents work together →- Callers and chatters can ask for a person at any point
- The AI hands over in the same call or chat thread, with everything it collected
- It answers only from your approved knowledge base, never guesses prices or policies
- AI replies are clearly marked, and every conversation is recorded and logged
