You can communicate with and manage customers in bulk across multiple channels. With bulk messaging, you can send messages to multiple channels simultaneously while tailoring your message for each channel. You can perform any combination of the following bulk operations with a single click:

  • Send a unique email
  • Send a unique SMS
  • Send a unique chat
  • Create a unique note

For example, you could send a bulk email message to your customers about shipping delays due to a storm and provide a note for users to read internal-only context about how to communicate with customers if they respond.

Compose your bulk message

Once you select the channel(s) to which you want to send a bulk message, you can start composing your message. If you plan on sending a bulk email message, we highly recommend looking at Postmark’s Bulk Messaging Best Practices article to ensure your messages reach your customers and prevent spam complaints. Too many spam complaints can cause your access to bulk messaging to be suspended, which is outside Kustomer's control.

The following fields and options are available. Please note that your options may change based on the selected channel.

  • Assigned User(s)
    Assign conversations to a specific user to ensure that they are routed to the correct user when a customer replies.

  • Assigned Team(s) 
    Assign the conversations to a specific user to ensure they are routed to the correct team when a customer replies.

  • Conversation Tags
    Add specific tag(s) to the conversation. This is helpful for search segmentation and reporting. For example, you can create a tag named "Order Replacement" and build a report on it.

  • From
    The email address or phone number from which the message is sent. This field is not available for Notes.

    Note: You cannot send a bulk email if you are using Gmail to send emails.

  • HTML Template
    Select an email template to send. The template can either be the email design or the actual canned message. This option is only available for email.

  • Message
    The area for you to compose your bulk message. You can format your message with basic formatting options using the text editor and personalize your messages using shortcuts and snippets. You can also attach images (.gif, .jpg, .png) and attachments to your bulk message if you are using Twilio (MMS) and Postmark (email). Individual files cannot exceed 5MB per file. The total attachment size cannot exceed 9.5MB total.

  • Queue
    Transfer the conversations to another queue.

    Note: Transferring a conversation to a different queue will unassign it from its current user.

  • To
    How many customers will receive your message.

  • Status
    Change the status of the conversation once it is created. This allows you to change a conversation status from Open to Closed and ensures that these messages don't appear in searches for users to work on.

  • Subject
    Subject line for your message.

If you have the outbound chat feature turned on, you will see the following additional options when sending a bulk chat message:

  • Message type
    Select between composing your custom chat message or using the conversational assistant. 

  • Brand
    Specify which brand the message is coming from.

  • Assistant
    Specify which conversational assistant to use. This option is only available if the outbound chat feature is turned on.

  • Starting dialog
    Specify what dialog from the conversational assistant to bulk send to customers.

Once you are done composing your messages, select Continue

Notes: 

  • You can not edit a bulk message once it is sent. 
  • Read receipts are not available on bulk messages.

Confirm there are no further edits, and select Send to send your messages.

Send a bulk message from a CSV

If you'd like to send out a bulk message to a list of users on a CSV, you can import your data with the CSV uploader

  1. Go to Settings > Administration > Data Import.
  2. Select Add Import > CSV and select Next.
  3. Review the preparation tips and then proceed to step 2.
  4. Name the import and then select Import new data and update existing data.
  5. Select Customers from the drop-down menu and then Save and Continue.
  6. Upload the CSV file and then proceed with the import.

The new import will open a newly created search. You can then send bulk messages to customers in that search.
