Reply to customers

Write replies, use canned responses and quick commands, quote a message, recall one, and understand reply windows and delivery ticks.

On this page

You answer every channel from the same reply box at the bottom of a conversation. Ha Tang sends your reply back where the customer wrote: into the website chat or your app, as a Zalo, Messenger or WhatsApp message, or as an email in the same thread.

You need Work access to Customer Support to reply.

Send a reply

  1. Open the conversation in Customer Support → Inbox.
  2. Type in the reply box. Press Shift+Enter for a new line.
  3. Press Enter or click Send.

Your message shows at once with a clock while it is being sent. On the website chat the customer sees that you are typing while you write.

In chat messages you can write **bold**, _italic_ and `code`. Links become clickable.

Faster replies

  • Canned responses. Type / at the start of a line to pick a saved reply, for example /gio for your opening hours. On the phone and Mac apps, the lightning button opens Mine and Team, and saves the message you are writing as a new one.

  • Schedule send. Write now, send later: the clock button next to Send on the web, a long press on the send button on the phone. See Schedule a message. See Canned responses.

  • Quick commands. Type @ at the start of a line to act on the conversation instead of writing:

    Command Does
    @c Resolves the conversation
    @ok Marks it handled without a reply: it leaves Unanswered only and its unread count is cleared
    @ + a tag name Adds that tag, or creates it if it is new (for example @giá-sỉ)

    Use the arrow keys and Enter or Tab to pick from the list. In an internal note, @ also lists your colleagues to mention.

  • AI suggestion. When the AI assistant drafts a reply, it appears above the reply box. Click Insert to edit and send it, or Discard.

  • Products and orders. Product sends product cards and Order creates an order with a payment link. See Product cards in chat and Payment in chat.

Quote a message

Hover a message and click the reply arrow to answer that message specifically. "Replying to «…»" appears above the reply box; the customer sees your reply attached to their message. Quoting works on the website chat, TikTok, WhatsApp, Telegram, LINE (for messages LINE allows quoting) and personal Zalo.

Recall a message

Hover a message your team sent and click the recall arrow, then confirm Recall this message?. Recalling works on:

  • Website and app chat: the message disappears from the customer's chat.
  • Personal Zalo: the message is recalled on Zalo.
  • Telegram: for messages Telegram accepted.

The message is replaced by Recalled, and an internal note records who recalled it and what it said. Other channels do not let a business take a message back, so the arrow does not appear there.

Reply windows

Some platforms only accept replies for a while after the customer's last message. The conversation header shows a green chip such as window open · 23h while you can reply, and a red window closed chip after that.

Channel Window
Zalo OA 48 hours
Messenger and Instagram 24 hours; up to 7 days when the HUMAN_AGENT tag is on for that channel (shown as past 24h · HUMAN_AGENT replies)
WhatsApp 24 hours; after that only templates approved by Meta, with Send a template
Telegram Business 24 hours

When the window is closed the reply box switches to internal notes, and a banner explains what the customer has to do. Website chat, email and the other channels have no window.

Email replies

In an email conversation the reply box adds To, CC, Add BCC and Subject, buttons for bold, italic, links and lists, and Send email. The buttons write the same marks as chat (**bold**, _italic_), and the email shows them formatted. Your signature is added automatically. Attached files go out with the email. Under each reply you see what happened to it: Email sent, Delivered, Opened, Opened, link clicked, or Email bounced, Marked as spam and Email failed in red.

Did the customer get it?

Under your message Meaning
Clock Sending
One tick Delivered to the channel
Two ticks Seen by the customer (on channels that report it)
Not sent with Retry Your browser could not reach Ha Tang. Check the connection and click Retry
Not delivered: and a reason The channel refused it. See Message not delivered

If the conversation is Closed, the reply box says "This conversation is closed". Reopen it first, or wait for the customer to start a new one.
