What is a read receipt?
Two blue ticks on WhatsApp. "Seen" under a message on Instagram. Small signals, but customers read a lot into them. A message marked as read with no reply can feel like being ignored, even when the business simply has not got to it yet. Here is what read receipts are, how they differ between apps, and how to handle them sensibly when an AI agent is reading your messages.
In one sentence
A read receipt is the signal a messaging app shows the sender once their message has been opened, such as two blue ticks on WhatsApp or "Seen" on Instagram and Messenger. For a business it is a small promise: once a customer can see you have read their message, they expect a reply soon.
In more detail
Read receipts exist so the person writing knows their message has landed and been looked at. Between friends, that is reassuring. Between a customer and a business, it sets a clock running. The customer now knows you have seen the question, so silence afterwards reads as a choice.
Each app does it a little differently. On WhatsApp, one grey tick means sent, two grey ticks mean delivered to the phone, and two blue ticks mean read. Instagram and Messenger show "Seen" under the message. LinkedIn shows a small picture of the reader when read receipts are on. Email mostly has no reliable read receipt at all, and many mail apps ignore requests for one.
Most apps let people switch read receipts off in their privacy settings. On WhatsApp, for example, turning them off usually means you also stop seeing other people's blue ticks in one-to-one chats. So the absence of a read receipt does not prove a message was unread. It may just mean one side has switched them off.
A read receipt is triggered by opening the chat or the message, not by replying. That matters when several people, or an AI agent, look at the same inbox. Whoever opens the message first sends the signal, whether or not they are the one who will answer.
The healthiest habit is simple: try not to show "read" until someone is ready to answer, or answer quickly once it shows. The example below shows the difference a few minutes make. Names and details are examples.
An example
| Time | What the customer sees |
|---|---|
| 10:02 | Leah asks on Instagram whether a sofa comes in green. Her message shows "Seen" at 10:03. |
| 10:03 to 13:40 | Nothing. Leah assumes she has been ignored and messages another shop. |
| Better: 10:03 | Her message shows "Seen", and within a minute the reply arrives: "Hi Leah, yes, the Arlo sofa comes in sage green. Would you like the fabric sample sent out?" |
| Also fine: 10:03 | If the answer needs checking, the reply says so: "Hi Leah, good question. Let me check with the workshop and I will come back to you by 2pm today." |
Read receipts on each channel
| Channel | What the sender sees | Can people switch it off? |
|---|---|---|
| Two blue ticks when the message is read | Yes, in privacy settings, for one-to-one chats | |
| "Seen" under the message | Yes, in message settings | |
| Messenger | "Seen", or a small profile picture under the message | Settings vary; treat it as usually on |
| A small profile picture under the message | Yes, in LinkedIn's privacy settings | |
| Usually nothing reliable | Most people never see read receipts by email |
Apps change their menus from time to time, so check the current settings in each app if you rely on one of them.
What customers assume, and what to do about it
| What the customer sees | What they often assume | What helps |
|---|---|---|
| Read, then a quick reply | This business is on it | Keep doing it |
| Read, then silence for hours | I am being ignored, or they do not want my business | A short holding reply with a real time |
| Not read for hours | They are busy or closed | An away message or opening hours on your profile |
| Read, then a reply that does not answer the question | Nobody really read it | Answer the actual question first |
Holding replies: before and after
When you cannot answer properly straight away, a short holding reply keeps the customer from feeling ignored after "Seen". The trick is to be specific about when. Names and details are examples.
| Vague holding reply | Better holding reply |
|---|---|
| "Will get back to you." | "Thanks, Sam. I am on a job until 3pm and will reply with a price by 4." |
| "Let me check." | "Good question. I am checking with the supplier and will message you by tomorrow lunchtime." |
| "Busy right now!" | "We are in the middle of lunch service. I will reply properly by 3pm, or call 01234 000000 if it is urgent." |
A real time does two jobs. It tells the customer they have not been forgotten, and it gives you a deadline you can keep. If you are using an AI agent, put the times it may promise in its notes so it never offers one you cannot meet.
Read receipts and AI agents
When an AI agent reads your messages, it can create read receipts too, depending on how it is connected. Two situations cause most problems.
- The agent opens a message, decides it needs a person, and the customer sees "Seen" with no reply. Fix this by having the agent send a short holding reply whenever it hands a chat over.
- The agent marks everything as read during a catch-up, and the owner can no longer tell what is new. Fix this by asking the agent to leave chats it has not answered marked as unread, so a person looks at them.
Here is a short note you can add to your agent's instructions. Names and details are examples.
Read receipts:
- Only mark a customer's message as read when you are replying to it, or
when you send a short holding reply.
- If you hand a chat to a person, send this first:
"Thanks, I have passed this to the team and someone will reply by
[time]." Then mark the chat as unread so the team sees it.
- Never leave a customer on "Seen" with no reply.Common mistakes
- Opening messages on your phone between jobs and planning to reply later. The customer sees "read" now and waits.
- Treating a missing read receipt as proof the customer has not read your message. They may have switched receipts off.
- Several people opening the same chat and each assuming someone else will reply.
- Using read receipts to chase customers, such as "I can see you read my message". It feels pushy and rarely helps.
- Relying on email read receipts to know whether a quote was opened. They are unreliable, and asking for one can feel intrusive.
Why it matters for your business
- A read receipt starts a clock in the customer's mind, so a quick reply or holding reply protects the sale.
- Customers who feel ignored after "Seen" often go elsewhere without saying so.
- Knowing that receipts can be switched off stops you drawing the wrong conclusions about a customer.
- When an AI agent shares the inbox, clear rules about read marks keep your team from missing chats.
- A short, honest holding reply turns "Seen" from a worry into a sign that you are on it.
How Spaces handles it
In Spaces, sending a read receipt is its own deliberate step. Your agent can mark a message from the other person as read, so they may see "Seen", where the account's connection allows it. Spaces also keeps its own read mark on each conversation, which works the same way on every channel, so the agent can mark a chat as read or unread for your own tracking. Marking a chat as unread is a handy way to make sure a person looks at it again.
An agent running on a server can also hear when a customer reads a message the business sent, through the message read event, where the platform reports it. That can be useful for knowing whether a reply has landed, as long as it is never used to pester anyone.
Email in Spaces is sent one message at a time to one person, with no open tracking. Whatever the agent sends, on any channel, is paced and counted against the account limits, and a chat handed to a person stays with that person until it is handed back.
In short
A read receipt tells the customer you have seen their message. From that moment, they expect a reply.
Answer soon after reading, or send a short holding reply with a real time. Teach your AI agent the same habit, and use the unread mark to make sure nothing slips through.
FAQ
Should a business turn off read receipts?
It depends on how quickly you reply. If you often read messages long before you can answer, switching them off can avoid customers feeling ignored, though on WhatsApp you then stop seeing theirs too. Many businesses keep them on and reply, or send a holding reply, soon after reading.
Does my AI agent create read receipts when it reads messages?
It can, depending on how it reads and what it is told to do. In Spaces, sending a read receipt is a separate step, so you can tell your agent to mark messages as read only when it replies.
What should I do if a customer has seen my reply but not answered?
Usually nothing for a day or two. People read messages and come back later. One gentle, useful follow-up is fine; repeated chasing is not.
Do read receipts work in email?
Not reliably. Many mail apps ignore read receipt requests or ask the reader first. Spaces sends emails with no open tracking.
Can I tell if a customer has switched off read receipts?
Not for certain. If you never see blue ticks or "Seen" from someone who clearly replies to you, they have probably switched them off. Treat a missing receipt as unknown rather than unread.
Is it rude to leave a customer on "Seen"?
Customers often feel it is, even when you do not mean it that way. A short "thanks, I will come back to you by 3pm" takes seconds and changes how the wait feels.
How do I stop my team missing chats that were opened but not answered?
Use the unread mark. In Spaces, your agent can mark a chat as unread when it hands it over, and you can give the chat an owner so one person is clearly responsible.
