Find out about Inbox in Klaviyo, which allows you to answer customer questions and provide support. Inbox includes both SMS and web chat tickets. 

With Inbox, also called two-way messaging, it’s easy to provide support to customers, building trust and loyalty along the way. 

Use cases for Inbox

Use cases for Inbox

The main purpose of Inbox is to offer support to customers.This is good for businesses:

  • With a dedicated support team. 
  • Looking to offer support, either for the first time or during peak seasons. 
  • Wanting to support via either SMS or web chat. 
Key terms

Key terms

  • Inbox
    Where your chats with customers are displayed. The inbox shows all messages sent between you and the customer via either text or web chat. 
  • Ticket
    Also called a chat, conversation, or support message, a ticket is a 1-on-1 communication between your brand and a customer. 
  • Message thread
    List of messages exchanged between you and a customer. The message thread in Klaviyo displays messages from flows, campaigns, SMS keywords and their responses, as well as support messages. 
  • Inbound message
    Any message sent to your brand. For instance, if one of your SMS subscribers texts “HELP,” that is an inbound message. 
  • Outbound message
    Any message that your brand sends, including flows, campaigns, keyword responses, etc.
How Klaviyo Inbox works

How Klaviyo Inbox works

A new ticket appears in the Inbox tab when someone either:

  • Sends a message via web chat. 
  • Texts your phone number and does not include a keyword. 

You can reply back to anyone via web chat; however, for SMS, that person must be an SMS marketing or transactional subscriber. 

You cannot: 

  • Open a ticket with a customer: they must message you first.
  • SMS-only restrictions:
    • Text anyone who isn’t currently consented to SMS (either marketing or transactional). 
    • Use Inbox with a branded sender ID (also called alphanumeric sender ID), as this type of number cannot receive inbound text messages. 
Number of tickets per profile

Number of tickets per profile

In addition, messages come from different channels (1 SMS and 1 web chat), these will appear as separate tickets. 

With SMS, messages always appear in a single message thread, even if the ticket is closed and then reopened at a later date. 

Each web chat session creates a distinct ticket. Once closed, a web chat ticket cannot be reopened. When someone writes in again, a new ticket is created. This means that the same customer may have multiple tickets.

Navigating through the Inbox tab

Navigating through the Inbox tab

Before you start using Inbox for SMS, update your auto-responder for when no keyword is recognized so it only sends to non-subscribers.

To view your messages in the Inbox: 

  1. Select Inbox in the left-hand sidebar. 
  2. Review the inbox for any inbound chats.
    • A blue dot indicates a new message.
See messages and profile information

See messages and profile information

Once you click into a chat, you can:

  • View the last 50 messages between you and the profile, including any flow, campaign, and auto-responder messages that you sent
  • See information about the profile, including: 
    • Whether they’re a subscriber. 
    • Location, if available. 
    • Recent activity. 
    • Recent orders (Shopify only).

Inbound images and videos (i.e., media the subscriber sent to you) do not appear in the message thread; however, you can see any images you send to the customer. 

View recent activity

View recent activity

Within a chat, clicking the Activity button on the right shows a list of recent events. You can filter this activity based on the metric you want to see.

This can help you see what the subscriber has done recently. For instance, did they recently subscribe? Did they receive a flow or campaign message, or did it fail or bounce? This can help inform your conversation. 

If you need more information than what’s shown, you can also go to that subscriber’s profile. There, you can get more details about a specific event

Check recent orders (Shopify only)

If Shopify is your ecommerce platform, you can also see someone’s recent purchases. 

After you click Orders, you can view details about that customer’s purchases, including what products they ordered, how much it cost, and more. 

Chat statuses  

Chat statuses  

A chat can have 1 of 3 statuses:

  • Open
    Indicates that a chat is ongoing, such as when you haven’t responded or are waiting for the customer to reply. 
  • Snoozed
    Used to temporarily hide a chat and remind you of it later today, tomorrow, or in 1 week. 
  • Closed (also called archived)
    Indicates that a chat is complete and you no longer want to see it in your inbox. Closed  SMS chats can be reopened, either from within Klaviyo or by the profile sending another message. Closed web chats cannot be re-opened.

In addition, a chat shows as either read or unread. The unread indicator appears as a blue dot next to that conversation.

Blocking a profile

Blocking a profile

If you no longer want to receive messages from a profile, you can block them. 

Once you block a profile: 

  • Klaviyo closes the chat from this profile.
  • You will no longer be notified about new messages from this profile. 
Key settings for Inbox

There are a few key settings for Inbox, but their availability depends on the channel. 

 SMSWeb chat
Notifications about new messages via email
Auto-responder
Automatically shorten links
Welcome message
Office hours

Notifications about new messages (SMS only)

Notifications about new messages (SMS only)

There are 2 options for new ticket notifications

  • Email notifications (off by default). 
    • Sends an email to any number of email addresses when you receive a new message in the inbox. 
    • Recommendation: turn on this setting if you plan to use Inbox to provide customer support; otherwise, leave this setting off. 
  • Unread message indicator (on by default) 
    • Shows how many unread Inbox you have (i.e., this is by the number of profiles who have texted, not by the number of unique messages). 
    • Recommendation: leave this setting turned on so you can monitor the number of messages coming in.
Auto-responder (SMS only)

Auto-responder (SMS only)

Your auto-responder is an automatic reply when someone texts your number and doesn’t use a recognized subscribe or compliance keyword (such as STOP, JOIN, or HELP). 

Recommendations: 

  • For those who want to use Inbox for support:
    • Change the auto-responder to send only to non-consented profiles. 
    • Update the message to be something like: “{{Organization prefix}}: We are unable to respond as you have not consented to receive SMS. For help, reach us at {{email}}.” 
  • For those who don’t want to use Inbox for support: 
    • No change is needed, as the default is to send the message to all profiles. 

Automatically shorten links (SMS only)

Automatically shorten links (SMS only)

This setting, which is on by default, automatically shortens any link in your outbound messages. Shortening links is beneficial because it: 

  • Uses fewer characters in any outbound SMS messages. 
  • Allows revenue to be attributed within Klaviyo. 

Recommendation: keep this setting turned on.

Learn about the different types of shortened link that are available. 

Office hours and welcome message (web chat only)

Office hours and welcome message (web chat only)

In Customer Hub, you can set both your: 

  • Welcome message (i.e., what sends once someone initiates a web chat)
  • Office hours, so you can set different responses depending on the time of day or day of the week.

Filters for Inbox

Filters for Inbox

You can filter your tickets by: 

  • Status (open, closed, or snoozed)
  • Unread vs. read 
  • Responses attributed to certain campaigns or flows (SMS only)
How are SMS tickets attributed? 

An SMS message in a ticket can be attributed to a specific campaign or flow. It works like this: 

  1. You send out an SMS campaign (or flow). 
  2. A customer texts back within seconds.

In this case, the customer’s message is attributed to the message you sent. 

Note that: 

  • The customer must text within your attribution window (the default for SMS is 24 hours). 
    • If a customer replies outside of this window (e.g., more than 24 hours later), their reply is not attributed to any message in Klaviyo. 
  • Only the first message is attributed. 
    • Example: if a customer replies with several texts in quick succession, only the first is attributed. The other replies are not attributed to any message in Klaviyo. 
  • Attribution is based on the last message the customer received. 
    • Example: say a subscriber receives a campaign and then a flow. In this case, the customer’s message is always attributed to the flow message. 

Replying to subscribers

  1. Click into the ticket that you want to respond to.
  2. Click into the text box below the message history and create your response. 
    • If it’s an SMS message, please note that you can only reply to SMS subscribers. Otherwise, the response field is grayed out. 

In your message, you can include images, GIFs, emojis, and coupons just like you can in any other SMS. You can also send multiple messages in a row

Best practices for two-way messaging

2 important things to remember when using two-way messaging are:

  • Respond quickly
  • Check recipient’s local time (if not responding immediately)

Respond to messages quickly

People expect a quick response when they text, much faster than when they send you an email or fill out a customer support form. Thus, ensure that you have the resources to reply quickly and meet demand.

When it comes to SMS support, quicker response times are key. Aim to text back within the hour, and make sure that you are responding to all incoming messages. 

Check recipient’s local time (if not responding immediately)

If someone texts you outside of your regular support hours, make sure you check their timezone before texting back. 

If a profile’s location is available, you can see this by clicking the name or number within the ticket. Then, look up the timezone for that location. 

Avoid sending during the following hours in the recipient’s local time:

  • Before 8 a.m.  
  • After 8 p.m.
