Learn how to create and send an SMS campaign in Klaviyo. Note that the process is almost exactly the same for MMS campaigns. The only difference is that you add an image or GIF during the content creation stage.  

What is an SMS campaign?

An SMS campaign is a one-time text message to a list or segment of subscribers, notifying them of events such as product launches, flash sales, or other promotions. You can set an SMS campaign to send either immediately or at some point in the future.

Before you begin

Before sending an SMS campaign, you must have:

  • Turned on SMS
  • Collected SMS consent
    • Note: having someone's phone number does not count as consent; someone must have explicitly agreed to receive SMS marketing messages

You should also have a list or segment of those who you want to send to, such as everyone who is subscribed to SMS.

Campaigns vs. flows
Campaigns Flows
1-time sends that are manually scheduled Automated and ongoing sends
Sent to a specific list or segment Triggered by customer actions or profile properties
Content is more broad with limited personalization Content is more specific and can be highly personalized

SMS vs. email send options

Note that unlike with email, you cannot use the following send options for SMS or MMS campaigns:

  • Determine recipients at send time
  • Smart Send Time
