Order #48627 arrived damaged
Marcus BellTo: Northwind Support <[email protected]>

Hi there,

My standing desk arrived yesterday and one of the hinges is cracked, so the top won't lock level. Photo attached. Can you send a replacement part?

Hi Marcus, sorry the desk arrived like that. I can see the cracked hinge in your photo, so a replacement hinge kit ships today at no cost and arrives Thursday. No need to send anything back.

The queue stops being the job

01

Replies in minutes, not days

Order questions, returns and how-tos get a complete answer while the customer is still at their desk, not after the weekend.

02

No Monday morning backlog

Emails that land overnight or on Sunday are already answered and closed when your team logs in.

03

Your team reads what matters

Routine emails are handled and closed. What reaches a person is the smaller set that truly needs judgement.

Email that reads like your team wrote it

Every reply is a real email: your sender name, the full thread behind it, proper formatting and the customer's own language.

Frequently asked questions

You decide. Turn on the AI note in the email settings and every reply ends with a short line such as "This reply was written by our AI assistant." The display name and signature are yours, so the email still reads as coming from your support team.

Replies go back into the same thread, so the customer's mail app shows one conversation. When the customer answers again, the agent reads the earlier messages in that thread before it writes, instead of starting from the latest line.

The agent reads PDFs, images, CSV and plain-text files that arrive with an email, up to 10 files per message, and can quote what it finds, such as an order number on an invoice or the damage in a photo.

Yes. Keep your existing support mailbox in Microsoft 365, Outlook or Gmail and forward it to your agent's address. The setup screen links the forwarding steps for Gmail and Outlook.

Automatic mail such as out-of-office replies, delivery notices and auto-acknowledgements is turned away before the agent reads it. Newsletters and bulk mail are recognised and skipped without a reply, so credits go to emails a person actually wrote.

Three steps in the dashboard: choose the address customers write to, send yourself a test email, then turn email on. Forwarding an existing inbox takes a couple of minutes.

Email replies use the message credits that come with your plan; there is no separate email fee. Compare credit allowances on the pricing page at /pricing/.
